Error: The reference assemblies for framework ".NETFramework,Version=v4.7.1" were not found #2808

Open heaversm opened 5 years ago

heaversm commented 5 years ago

Environment data

dotnet --info output: 2.2.1 VS Code version: C# Extension version: 1.17.1

Steps to reproduce

Try to use the Unity Debugger. Error gets thrown in VSCode

Expected behavior

No errors

Actual behavior

Errors on startup

The .NETFramework is not available on a Mac. I'm not sure if it is needed for this extension - if it is, the extension is useless on Mac. If it is not, there should be a check for the platform or something. Regardless, if I try to debug Unity, it crashes as soon as I hit play (Debug adapter process has terminated unexpectedly (spawn mono ENOENT)

rchande commented 5 years ago

@heaversm You need to install mono (https://www.mono-project.com/download/stable/#download-mac). I recommend installing version 5.18 from that page instead of using homebrew/etc package managers. (copied from https://github.com/OmniSharp/omnisharp-vscode/issues/2555#issuecomment-456998688)

heaversm commented 5 years ago

I installed mono: mono --version : Mono JIT compiler version 5.16.0.221. I believe at this point I have tried both brew and a direct download - do you know how to use the version over the brew version?

batbaatap commented 4 years ago

Did you install Mono framework and .net core, if so write on your terminal below: export FrameworkPathOverride=/Library/Frameworks/Mono.framework/Versions/Current

jscheel commented 4 years ago

I know I'm resurrecting a year old thread, but I'm running into the same issue. I have latest mono installed, I've exported FrameworkPathOverride, but I still end up with the same error.

@jscheel can you share the OmniSharp Log from the project you are working on?

Try adding export FrameworkPathOverride=/Library/Frameworks/Mono.framework/Versions/Current to your ~/.bash_profile or ~/.zshrc or whichever terminal you use. Restart VSCode before trying again.

DTX-92 commented 4 years ago

@bmschwartz You are my hero! When I moved FrameworkPathOverride from the global PATH to .bash_profile, OmniSharp started with no errors

bmschwartz commented 4 years ago

Glad I could help. I spent a few hours trying to figure it out as well.

@bmschwartz Bro, you're like an archangel bringing this solution to us!

That worked for me too! Thank you very much!

Worked for me on ubuntu 20.04 I added the line to my ~/.bashrc and the restarted visual studio code

Thanks a lot!!

Mangi91 commented 3 years ago

@bmschwartz that was it! Thanks!

o8ruza8o commented 3 years ago

How can that possibly work on Ubuntu 20.04? It is a MacOS path to mono framework which does not exist on Ubuntu.

this is it, thanks @bmschwartz .

Sakari369 commented 3 years ago

Just clarifying that for me I needed to put this "export FrameworkPathOverride=/Library/Frameworks/Mono.framework/Versions/Current" to ~/.bash_profile.

I dont use bash as my shell, but seems it is loading it from there anyway on macOS.
