"Run Cell" does not pickup on jupyter installed via virtualenv but conda works

Environment data

• VS Code version: 1.29.0 5f24c93878bd4bc645a4a17c620e2487b11005f9 x64

• Extension version (available under the Extensions sidebar): 2018.10.1

• OS and version: Ubuntu 18.04

• Python version (& distribution if applicable, e.g. Anaconda): pipenv with python 3.7

• Type of virtual environment used (N/A | venv | virtualenv | conda | …): virtualenv

• Relevant/affected Python packages and their versions: -

Actual behavior

When using a virtualenv/pipenv environment clicking on “Run Cell” yields the error msg: Running cells requires Jupyter notebooks to be installed.

(But it works with conda.)

Expected behavior

Cell is executed.

Steps to reproduce:

mkdir hello
cd hello
pipenv --python 3.7
pipenv shell
pipenv install jupyter
which jupyter
# /home/somebody/.local/share/virtualenvs/hello-UXM3mEkX/bin/jupyter
# jupyter notebook also works on its own

Open vscode, select the interpreter for the “hello” pipenv environment, create a file demo.py with the following content:

#%%
print("hello")

Clicking on “Run Cell” yields the error msg: Running cells requires Jupyter notebooks to be installed.

nbconvert is not available via the venv, but jupyter-nbconvert is.

Update: It seem to be related to how you start vscode.

• When vscode is started from the activated virtualenv code . then “run cell” works.
• When vscode is started without any environment (and jupyter is not available in the current PATH)
  • “run cell” works with a conda interpreter
  • “run cell” does not work with the interpreter from the virtualenv

conda and virtualenv seem to be handled differently. Is this a bug or accepted behavior?

@rchiodo Yes, works as expected when starting code with environment activated in terminal. Not using pipenv though (as in microsoft/vscode-jupyter#3774). If I understand correctly, pipenv uses VirtualEnv, while pyenv-virtualenv uses native python3 -m venv despite its name
