cannot start process because a file name has not been provided

I installed 2019.3.0 today, new project, new step, open step, engine popup cannot start process because a file name has not been provided ， How to solve thank you

 

Dealing with a similar thing. Everything was fine and then out of no where, anything added to my project was not being updated in the VS solution. I basically had a broken solution. I read that removing the vs files will trigger unity to regenerate them. Nope. Nothing. I cannot even open the project in VS anymore.

Going to have to start anew - Maybe I'll avoid using beta / alpha versions of Unity for now.

 

I have same issue, Please help!

 

I have the same issue, even after trying to update Visual Studio Editor package to version 1.0.11. Any extra info on that? I started my uni project on 2019.3.0a2 for some reason and now i do not have the time to redo all my work. I shouldn't have went for the alpha version, but i just downloaded the recommended one by the unity hub.

 

Yup, even update the VS to new version still bug out of nowhere: Cannot start process because a file name has not been provided ??

 

I'm making my first ever game in unity and I follow tutorials but they're all old at least over a few months old

 

also I fixed my script and it says no issues found but I can't play test.

 

Seeing this bug in 2019.2.b6. Attempted to remove and reinstall the Visual Studio Editor package, no change. I have the same project synced on another machine, with a slightly older version of Visual Studio and same version of Unity, and no error there.

Bug report 1165550

 

FYI, in my case, 2019.2.b6 was not setting the external editor to Visual Studio on install, resulting in this error message. (Apologies to airwolf - I should have looked at external tools right away, but I missed that in his post.) Going to preferences and changing it from 'internal' to 'visual studio' fixed it. So, in my case, the question becomes: why did Unity not set the external editor to VS when it installed, considering that it installed VS. Also: the error message could be clearer - it seems like Unity isn't handling the internal setting gracefully.

 

Yes this solved the issue thank you!!!!

 

Thank you ,it worked

 

Hello Guys!!... I have followed the proposed solutions and they didn't work out for me.

I have changed in my External tools my Script Editor to Visual Studio 2019 (Community) and in my package manager I have only got Visual Studio Code Editor version 1.0.7, but I haven't got the Visual Studio Editor 1.0.11 package in the manager.

I'm trying to find a way to build an apk to the Oculus Quest using the LWRP with Unity 2019.2.2f1

I read it was possible here: https://forum.unity.com/threads/lwrp-and-oculus-go.546417/

I'm still getting this error:

InvalidOperationException: Cannot start process because a file name has not been provided.

Any ideas on workarounds or solutions?

 

I just installed 2019.2.6f1 and I'm getting the same error. I've tried the solutions posted here but none work. I'm using VS Community 2019. When clicking a c# script it does open VS but Intellisense is not working at all.

 

@miniwolf_unity I am getting the exact same issue as Amon, with the exact same version of Unity. Installed everything today and I haven't even written my first line of code before running into trouble. VS opens but it doesn't recognise Unity or somesuch. None of the solutions work. As for Intellisense, sln and whatnot - I don't know enough to go poking around on my own

 

I was running visual studio as administrator. So running unity hub and unity itself force run as administrator solved my problem.

 

I installed Unity 2019.2.6f1 and started working today. I created a script and defaultly it opened in notepad. I changed it too Notepad++ for smooth coding and I wrote the necessary script for the game. But once I closed it and entered Unity, an exception was shown like "InvalidOperationException:Cannot start process because a file name has not been provided."

Also the variables imported from the script are incomplete. How to solve this?
Please help.

 

I ran into this issue tonight. Spent a long time going through every little change I made, until I discovered that I had a bug in a conditional compiler argument that wouldn't be enabled in play mode:

#if UNITY_STANDALONE && UNITY_EDITOR

My editor was set to WebGL at the time and the editor 'played' fine, but the error inside this conditional block for some reason caused the "File name has not been provided" error consistently, seemingly while not really affecting the actual project in the editor.

I doubt this is everyone's case, but hopefully it helps someone.

 

have this bug in 2019 3 6, only when using build & run, build only works just fine

 

IT's the same for me on 2019.2.21f1 and 2019.4.18f1. Build only works find but build & run throws the error.

 

I tried to downgrade a project from 2019 to 2018 and I get it if I try to play it.

 

I noticed that I would often get that error "Cannot start the process because a file name has not been provided"

One reasonable step you can do is:
1. Go to Edit > "Preferences"
2. Go to the External Tools tab
3. Set "Visual Studio" as the External Script Editor

 

I still have this problem with Unity 2019.4.18. I tried all fixed described here but was not able to make it work.
