Bug Empty error in console

Hi guys,

I recently installed Unity Linux 2017.3.0f1 and when I added a new C# script I get an empty error in the console. I won't be able to run it in Unity as it will show an error (refer to attached image). Non of the solution offered in the forum work, .e.g., changing the locale to english US.

I'm able to use both MonoDevelop and VS code with all updates from the best I can get from the internet.

I'm running Debian 9. When people say fresh install, what does that entail? rm -r <folder> ?

 

While you wait for the bug to be fixed, try double clicking on the empty error message in the console. Doing this should open MonoDevelop or VS on the line that contains the error. Once you've spotted the error, you should be able to fix it and use the script.

 

I tried double clicking on it. Nothing happens. If I remove all scripts, the empty console error goes away.

The error exist by simply:
1. Start a new project (either 3D or 2D, tried both)
2. Create a new C# script with any legit name
3. Empty console error appears
4. Been troubleshooting for days now
5. Guess I have to fork out for a Windows laptop. Current system is >5 years old (hence running linux).

 

I have the same issue. Create new project. Create a script. Empty Error message in console that can't be cleared.
Linux Mint 18.3 with Unity 2017.3

 

Hi, I have this as well.

I am using Linux Mint 18.3 and latest unity3d release.
Unity works fine until I start using scripts.
There is always empty error that can't be removed. I tried checking for mistakes in script, then just create a new script.
Also I've tried downloaded monodevelop, sublime text 3 as script editor.
Every time it is the same: the script does not compile with empty error.
Example project does not work as well.

It also says "No MonoBehaviour scripts in the file..." etc, despite the file being just created.

 

It may sound very stupid, but the problem disappeared when I installed mono-complete package.
Probably unity's internal compiler doesn't work or smth.

 

Greetings everybody. I have to say that i experience exactly the same problem as the user @danz_the_deadly (and all other above him). I get empty compiler errors already when creating a default script file with unity. I am currently working on a unity course where also all the projects coming from the previous version do not compile and run.
Could this be related to a missing MonoDevelop install? I am currently using vim as a simple code editor. Do i need to point unity to a C# compiler or is it usually bundled with it?

 

Hello there! I had the same issue. To solve this you have to install all system dependencies listed in first post in this topic https://forum.unity.com/threads/unity-on-linux-release-notes-and-known-issues.350256/ under "Dependencies and Recommended Packages" part.

Enjoy!

 

Hello friends...!!
We could solve the problem by running the following command in the terminal:
$ sudo apt-get install monodevelop mono-reference-assemblies-*
which will install all the required dependencies to run Unity3d properly...in Linux Mint 18.3 KDE
I did it last night...!! and it works for my system...

Hi everyone!

I've had the same issues. However I'm running it under Fedora 27. Installing mono-complete and referenceassemblies-pcl did not work as well. Have anyone here ever properly run Unity 2017 on Fedora 27? It would be great to share the workaround for this issue.

Here is my full log :

 

for some reason I had missing dependencies too, like some 5 libraries was missing!

 

I was wrestling with the same issue half day. If you installed your build from the new Download Assistant definitely make sure you have necessary dependencies.

 

Thanks man, this helped me.

 

have the same problem but am running windows... if it was linux i could have just installed the dependencies any help?

 

Same problem But On Windows Please Solve This One

 

I have the same error in Windows too :-(

 

Hey guys. I have the same problem in Windows.
And i figured out - this have some kind of connection with chosen C# version.
I have this problem with 4.x version, while 3,5.x - ok
Go to BuildSettings/ProjectSettings/OtherSettings/ScriptingRuntimeVersion and change it
Hope this'll help

 

Could you specify where these folders are?I searched whole hdd with mask ScriptingRuntimeVersion - no luck

 

Build Settings, in editor, the build settings you choose when you want to... build your game; it's not a folder.

 

Thanks found it.Indeed the problem goes away with 3.5.But what if my project relies on 4.x features?

 

Hi, I found a solution to this bug on windows that does not require downgrading to .Net 3.5 (which appears to be deprecated now).
I don't know the exact component, but installing the entire Microsfot .NET desktop development suite seems to have fixed the issue. If someone wants to narrow down the component that would be nice, but what I can vouch for is installing the entire package, and then you can safely use .NET 4.x without the empty errors.

 

fixed this by upgrading to win10 from win7.
Installing latest windows updates also may fix the issue.

 

same problem on window 7

 

Sorry, but that is not a solution. Windows 7 is officially still supported by Unity, so there should be no errors.

Any other way to solve this issue?

 

Thank you! This working!

 

Thank its work

 

Yes I know.For some reason my Win7 was unable to update and the were about 200+ windows updates to be installed.Some of these updates I believe were .Net-related.
So the solution may be "check you have all OS updates installed"

 

see https://forum.unity.com/threads/unity-on-linux-release-notes-and-known-issues.350256/
I fix this bug with above link > "Dependencies and Recommended Packages", install all dependencies
this is my ruby script:
```
deps = %w(gconf-service lib32gcc1 lib32stdc++6 libasound2 libc6 libc6-i386 libcairo2 libcap2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libfreetype6 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libgl1-mesa-glx libgl1 libglib2.0-0 libglu1-mesa libglu1 libgtk2.0-0 libnspr4 libnss3 libpango1.0-0 libstdc++6 libx11-6 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxtst6 zlib1g debconf npm)

system %Q(sudo apt install #{deps.join(" ")} -y)
```

 

I had the same problem with 5 completely blank errors in the console on Kubuntu 19.04. I could find the actual errors in the Editor.log file, indicating that libssl was missing. So I installed libssl1.0.0 manually and all errors were gone.

So if you are having such issues as well... try checking out the Editor.log file. It probably tells you what's wrong

 

I confirm the existence of the problem. Works in Ubuntu 18.04 not working in Ubuntu 19.04. Displays 5 empty fields with errors when creating or opening a previous project.

 

Also experiencing this error in 16.04 (will be upgrading soon) on a new project. I have all the dependencies for Unity and MonoDevelop. When I change ScriptingRuntimeVersion to NET 3.5, I get about 60 new errors all along the lines of:

New Unity Project/Library/PackageCache/com.unity.textmeshpro@2.0.0/Scripts/Runtime/TMPro_UGUI_

Private.cs(1089,59): error CS1644: Feature `out variable declaration' cannot be used because it 

is not part of the C# 4.0 language specification

So I'm sort of stuck since I can't use 3.5 or 4.x.

 

THX!

Had the same problem on a fresh Ubuntu 19.04 install. It worked perfectly on another machine which was upgraded to 19.04 and had libssl-1.0 still installed. As a workaround installing the 18.10 / cosmic package works ( https://packages.ubuntu.com/cosmic-updates/amd64/libssl1.0.0/download ) but Unity needs to fix it eventually.

P.S. the issue only seems to be present in 2019.1 and 2019.2. 2018.4 worked fine without the fix.

 

Turns out I also had the same issue with different libraries. After upgrading to 18.04 earlier, I ran Unity and checked my Editor.log (thanks for the reminder lol). Apparently, libunwind.so.8 was missing so I ran

sudo apt-get install -y libunwind-dev

and that fixed it!

 

It looks like this has been fixed in 2019.3: https://issuetracker.unity3d.com/issues/linux-roslyn-fails-if-there-is-a-newer-libssl-than-1-dot-0. It's due to Ubuntu 19.04 coming with a version of libssl that Roslyn can't detect. Installing libssl-1.0 from cosmic-updates (alongside 1.1) as mentioned above is a valid workaround until you can upgrade.

 

For those who can see in the log that it is indeed an issue with libssl, you can follow the simple instructions here :
https://forums.eveonline.com/t/unmet-ssl-dependency-for-the-linux-launcher-on-ubuntu-19-04/144153

Worked like a charm for me and I hope it does for you also.

Ubuntu 19.04

 

not working for me

 

Thank you! This helped fix my issue.
Running Ubuntu 18.04 LTS with Unity 2019.1.14f1

 

Install this works with me : https://packages.ubuntu.com/xenial/amd64/libssl1.0.0/download

2019.2.8f1

 

hello. what did you install? can you provide me a link please?

 

Wanted to provide an update to this issue for Windows 10 users. In my case, this error was related to a problem with a Roslyn bat file. The editor log stated that the unity_csc file could not be found. This may or may not be true for all of you, but this may work for you.

Head over to this thread: https://answers.unity.com/questions/1680858/blank-console-error-on-empty-project-with-a-single.html

Look at the top accepted answer and follow those steps. Props to @adrisj7.

 

If you struggle like me with errors to install libssl1.0.0 try

sudo apt --fix-broken install

It fixed my libssl !

 

If you are running fedora install monodevel, mono-tools, mono-tools-devel packages (sudo dnf install).
I might have forgot one or two dependencies, but all of them start with mono

 

i had this error on win7, i used windows update and installed all the available updates and it fixed it. not sure which update solved it tho, there were so many updates

 

For me this same problem occurred in windows 7 but it appears twice, is it because the DDI version is 10 and the directx version is 11?

 

Short:
I solved it on Linux by exporting a variable:

export DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1

I added this line to my

 .profile 

so that it will work when I log in.

I also installed

dotnet-sdk

but I don't know if not doing it would have affected the result.

Long:

I am using Arch Linux.
I installed Unity Hub from AUR.
And I installed editor version 2020.3.33f1.

I created a new 3d project and when in

Load Scripting assemblies

I got the following popup error:

Enter Safe Mode?



The project you are opening contains compilation errors.



Entering Safe Mode allows you to resolve these errors without waiting for the rest of your project to import.



If you select Ignore ( not recommended), your project will continue to import, but it may be in a broken or unusable state.

I chose the ignore option.
When it opened I had two empty errors in the console.

After some research I went to:

Unity/Hub/Editor/2020.3.33f1/Editor/Data/Tools/Roslyn

And ran:

./csc

I got this error:

Process terminated. Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

   at System.Environment.FailFast(System.String)

   at System.Globalization.GlobalizationMode.GetGlobalizationInvariantMode()

   at System.Globalization.GlobalizationMode..cctor()



...

So I researched more and found the solution:

export DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1

And I added this line to my .profile.

 

This fixed it for me on Gentoo, I was running into this error when upgrading my project from Unity 2019 to 2020.

 

I encountered this issue on openSUSE Tumbleweed after one of the rolling updates, therefore I imagine it might happen on other rolling distros as well (e.g. Arch Linux).
I'm using Unity version 2020.3.34f1.

Setting the dotnet globalization variable did not help (or at least I couldn't get it to work properly).
In the end I figured out this had to do with the libicu package version (which dotnet uses for globalization on Linux).

After the last rolling update my installed version of libicu is 71 (you can check this by running zypper se libicu, you should see an "i" next to one of the packages - this indicates which ones are installed, in my case it was libicu71).
The problem in Unity was resolved once I installed an older version alongside the most recent one. On openSUSE I used opi to install version 69 (the command is opi libicu69, then just pick the entry which says libicu69).

 

This worked in my Manjaro system!

 

Have you solve Problem bro . Then please help me to solve this problem . how to solve this problem please tell me bro.
Thanks in advance.
