pipenv venv not activated before Code Runner executes Python script file

Windows 10 1803 (17134.407) Python 3.7.1 pipenv 2018.10.13 VSCode 1.29.1 Code Runner 0.9.5

When running a Python script using Code Runner the virtualenv is not activated before the code is run in the terminal for the first time, causing my code fail. The virtualenv is activated after the script fails and I can then run my code successfully until I close the terminal window. A minimal working example is shown below.

The venv is activated in VSCode and the correct Python interpreter is configured.

Here is the Pipfile for the project:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
numpy = "*"

[dev-packages]

[requires]
python_version = "3.7"

And here are all the Code Runner settings from my settings.json file:

{
    "code-runner.fileDirectoryAsCwd": true,
    "code-runner.respectShebang": false,
    "code-runner.ignoreSelection": true,
}

While I can get my code to work this is rather annoying. Does anyone have any ideas what might be causing this?

Having the same issue here. I seemed to have fixed it by both making it use the integrated terminal (zsh) and setting the executor map like such:

    "code-runner.executorMap": {
        "python": "$pythonPath $fullFileName",
    },
    "code-runner.runInTerminal": true

Hope this can help someone.

I don’t have anything new to add other than 5 months later I am seeing the same issue. The settings.json file that is autogenerated has content similar to:

{
   "python.pythonPath": "C:\\Users\\pconwell\\.virtualenvs\\ridgeplots-0xoO3BBx\\Scripts\\python.exe"
}

Which will not work at all. VS Code is (presumably) recognizing the virtual environment correctly as the code will run manually from terminal AND the correct virtual environment is showing the lower left corner of VS Code. If I use the above settings, I will get a ‘module not found error’.

If I change the above code to:

{
   "python.venvPath": "C:/Users/pconwell/.virtualenvs",
   "python.pythonPath": "C:/Users/pconwell/.virtualenvs/ridgeplots-0xoO3BBx/Scripts/python.exe"

   "code-runner.executorMap": {
       "python": "$pythonPath $fullFileName",
       }
   "code-runner.runInTerminal": true
}

The Code Runner will work BUT only after I run it the first time. (i.e. the first time I run Code Runner it gives an error, but the second time I run Code Runner it works.) The specific error varies from project to project, but the error will inevitably magically disappear the second time Code Runner is run.
