The compiler this script was imported with is not available anymore.

Hi,

I get this error message, with no more information :

Why ?

Thanks.

 

Well what script is it referring to? Where did this script come from? Have you just upgraded from a previous version of Unity? Give us some context if you want people to help with your question.

 

There is no context at all. I was working on a project ans suddenly this messages happens.
I created a new project and copied the script inside. The same.
I created a new project and created a new script, same message + "docarea OnGUI".
I update to 3.5.1, the same.
No matter what I do this message appears every time I compile.
Except that it don't happens with a new project / new script in 3.5.1.

Another strange thing. When I add my monobehaviour to a gameobject the "script" entry in the inspector show nothing and the script name is "script" in the inspector title bar.

EDIT :

Maybe I found. When the monobehaviour is inside the editor folder it don't appear in the component/script menu, but it can be added through script addComponent. I placed it outside the editor folder and the inspector is now correct.
The error message didn't show up anymore for now.

 

Too harsh man, I just had the same error & there is no context

Code (csharp):

1.  
2. The compiler this script was imported with is not available anymore.
3. UnityEditorInternal.InternalEditorUtility:GetMonoIslands()
4. UnityEditor.Scripting.Serialization.Weaver:WeaveUnetFromEditor(String, String, String, String, Boolean)

 

Hmm, I'm a bit hesitant to necro this thread even more but the title seems like something people would search for.

I am experiencing the same issue, around the time since I updated my unity version last December.
There have been more updates since but I cannot remember when the issue started sadly.

I do have a trace though, but it seems to be internal code.

I'm still looking into this on my end, maybe someone finds some use in this.

I have also seen this a lot recently; it seems to happen the most when my focus leaves the Unity editor. Moreover my MonoDev has been hard crashing about one in every 10 times I give it focus back. I've also been locked out of editing references so I have to regularly delete the monodev user cache. I'm on a Mac (10.12.3) w/ MonoDev 5.9.6 and Unity Pro 5.5.1f1. I'm doing a lot more with nested delegates (and nested anonymous delegates) which has been the only thing that's really changed in my project since this problem started. It's persisted through at least two updates and multiple reboots. I haven'd done a full uninstall/reinstall yet though. I think the crashing started with the december update (5.4 something? I can't remember).

Code (CSharp):

1. The compiler this script was imported with is not available anymore.
2. UnityEditorInternal.InternalEditorUtility:GetMonoIslands()
3. UnityEditor.SyncVS:SyncIfFirstFileOpenSinceDomainLoad()
4. UnityEditorInternal.LogEntries:RowGotDoubleClicked(Int32)
5. UnityEditor.DockArea:OnGUI()
6.  

 

Yeah, same here. I have some nested MonoBehaviours, and every one of those causes this error. It started with an update, maybe an update of the Visual Studio tools of Unity. Wish there was a fix for this.

 

I was facing the same problem , i found a solution and it worked with me.

Apparently its caused when i have a script that the class in it doesn't have the same name as the script. for example having a script named "test" if there's no class with the same name in my script it will cause this error. so try to rename your class to be the same as the script name

 

Yeah, I know. But I don't want to do that. Especially as it worked before.

 

Maybe this script helps you.

Make any "Editor/" folder, put this file in it.
Put the button in "Tools/Compare MonoBehaviour" menu, and check files in log. (My English is so bad.. sorry )

I'm glad you necroed it! I'm having the same issue!

 

Your script has many errors

 

Still getting these damn errors. No context, no nothing.

 

Yes i've been plagued by this error over and over again in my project.

It also has the undesirable effect of making the compiler times much longer for some reason.

Nobody seems to have a definitive solution but the general feeling is that its either

a. MonoBehaviour mismatch in class name and file name
b. Multiple MonoBehaviour's in one file
c. Nested MonoBehaviour issue
d. Some issue with the Visual Studio Debugger

Can someone from Unity shed some light on this with a purpose of fixing it please ?

 

Honestly? bug report this stuff.

 

I can't. My project is massive.

 

Ow. Maybe someone else has a repro to be lucky with...

 

I just removed the third party package "Full Inspector" from my project and started getting this. My project is also massive, but if I have time I will try stripping it down and seeing if I can maintain the error in a smaller build for a bug report. Others should do the same as well (try removing all scenes and assets so the project still compiles).

I get the additional error of:

The compiler this script was imported with is not available anymore.
UnityEditorInternal.InternalEditorUtility:GetMonoIslands()
UnityEditor.Scripting.Serialization.Weaver:WeaveUnetFromEditor(String, String, String, String, Boolean)

 

I get this as well now, I think it came up sometime after an update to a new version of unity or possibly when switching branches in git. Maybe deleting the library folder might help if it's really something leftover from another branch which might have been on an older version of unity... not sure.

The compiler this script was imported with is not available anymore.
UnityEditorInternal.InternalEditorUtility:GetMonoIslands()
UnityEditor.DockArea:OnGUI()

 

Was this issue solved, started getting it?!

How to reproduce this Error:
Unity: 5.6x VS 2017
Start a Project (click play)
Switch to VS or an Editor (VS is what i used)
Make a change to the file, Save
Go back to Unity. It errors out with 10,000 errors and crashes.

Problem: It tries to reimport the files back into Editor and cannot do so, or some such internal logic.

The Debug log really needs an update hasn't been touched since 2000 or some such. ALSO also if Unity Internal spams the debug log it crashes. I can't do that, why should they.,
