Compiler Error

[kaleb-keny]

Thank you @fubuloubu for setting this up. Hopefully this is a good way to keep track of questions, so that other people who might have similar questions can find answers instead of looking inside closed issues.
So I am facing an issue with the vyper compiler and [Compiler Error] Error executing vyper: 'vyper' is not recognized as an internal or external command, operable program or batch file. So I never was able to have the auto-compiler work on VS Code, therefore I resort to brownie for compilation. Is this normal, or should the vy extension be able to autocompile the code as I write it?

Seems like a good task for https://github.com/vyperlang/vscode-vyper

Yeah I mean I installed the extension on the market place... https://marketplace.visualstudio.com/items?itemName=tintinweb.vscode-vyper through the vs code store... But the extension might not be loading right... No worries I'll have a look at the gh repository to see if it's a requirement I'm missing. Thank you

We forked it from this upstream repository, so would be a good place to start: https://github.com/tintinweb/vscode-vyper

I had the same issue today on my new PC. The cause and solution were in my case the following (I'm working on a Windows PC):

Cause:

• I used a virtual environment for my contract delevopment, therefore Vyper was only installed in the venv (by using pip install vyper).
• Therefore, the vyper extension in VS Code was trying to use the shell command vyper to compile.
• But this command only exists in the venv.

Solution:

• Go to your venv folder and look for the vyper.exe file (venv -> scripts -> vyper.exe)
• Copy the path to the exe file
• Go in VS Code -> Settings -> Extensions -> Vyper -> Change vyper Command to the path (e.g. C:\dev\your_project.venv\Scripts\vyper.exe)
• restart VS Code

Worked for me. Hope for you too.

works like a charm, on MacOS path is likely /Users/you/venv/bin/vyper

Just tacking on to this - I've had the same issue with VS code on Mac. I didn't install in a virtual environment, but VS Code is still returning the "[Compiler Error] Error executing vyper: /bin/sh: vyper: command not found". I've tried uninstalling and reinstalling the plugin, reinstalling vyper, to no luck. Any ideas?

[seekingtau]

Fixed the error by tracing the compiler and changing the compile command (basically what is done above). Thank you!
