'pipenv --venv' results in subprocess.CalledProcessError

[kylemart]

Here is a link to the original issue: microsoft/vscode-python#2968. It should contain all of the information required for this bug report.

In short, VS Code executes pipenv --venv behind the scenes when opening a Python project containing a Pipfile. For some reason, this is resulting in an error. I cannot reproduce this issue outside of VS Code...

---

Environment data

• VS Code version: 1.28.2 (7f3ce96ff4729c91352ae6def877e59c561f4850)
• Extension version (available under the Extensions sidebar): 2018.9.1
• OS and version: macOS 10.14
• Python version (& distribution if applicable, e.g. Anaconda): 3.7.0
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): pipenv

Actual behavior

Upon opening a project folder with an existing virtual environment, I get the following error message:

Workspace contains pipfile but attempt to run 'pipenv --venv' failed with 'Traceback (most recent call last):

Expected behavior

No error message.

Steps to reproduce:

1. Create directory.
2. Run pipenv install in the directory.
3. Open the directory in VS Code.

Unrelated question - what's the performance like on your machine? I opened master on vscode, and it started lagging horribly. I can't even edit a single file.

OTOH Sublime seems to work very smoothly.

In term of performance, VS Code actually runs very smoothly!

Hmmm that’s a new one. Looks like a shellingham bug. /cc @uranusjr

[uranusjr]

What happens if you run ps -ww -o pid= -o ppid= -o args= (basically the failing command itself) directly?
