Running bpython inside a virtualenv

Question

I have created a virtualenv and installed SQLAlchemy in it:

$ virtualenv alchemy
$ source alchemy/bin/activate
$ pip install sqlalchemy

import works in python:

$ python
Python 2.7.5 (default, Mar  9 2014, 22:15:05)
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlalchemy
>>> print sqlalchemy.__version__
0.9.7

But it does not work in bpython:

>>> import sqlalchemy
Traceback (most recent call last):
  File "<input>", line 1, in <module>
ImportError: No module named sqlalchemy

Why can't bpython find the package installed in the virtualenv, even though it is executed after source alchemy/bin/activate is called?

bpython must be installed in the virtualenv, otherwise the external, system-wide bpython is called:

$ source alchemy/bin/activate
(alchemy)[ 10:34PM ]  [ adamatan@rubidium:/tmp ]
$ pip install bpython
...
$ alchemy/bin/bpython
--------------
>>> import sqlalchemy
>>> print sqlalchemy.__version__
0.9.7

Is there a way to avoid this behaviour and access the /usr/lib bpython with the virtualenv? – user3467349 Dec 16 '14 at 21:34
Yes there is. You need to resource your activate script : $ source alchemy/bin/activate $ which bpython /usr/bin/bpython $ source alchemy/bin/activate $ which bpython alchemy/bin/bpython – loutre Jan 27 '17 at 08:59

bpython has the python it was installed with hardcoded in its shebang.

You can manually edit it to make it use the current python. Open the script by running for instance $ vi $(which bpython).

Then change the top line from eg. #!/usr/bin/python3 to eg. #!/usr/bin/env python3.

That should make it run using the venv's python. It's not supported officially by bpython but it has always worked for me on both Mac OS X and Ubuntu.

Run bpython as module works for me

mkdir workout && cd workout
venv shell --python=3.8
Install your dependencies, e.g., pipenv install gcloud
pipenv install bpython
python -m bpython

python -m bpython
bpython version 0.21 on top of Python 3.8.5 /home/dennys/.local/share/virtualenvs/workout-qTtsVfjR/bin/python
>>> from gcloud import bigquery
>>>

Bpython must be installed with pip3 inside each virtualenv

$ virtualenv . 
$ source bin/activate 
$ pip3 install bpython
$ pip3 install sqlalchemy
$ bpython

>>> import slqalchemy

If bpython does not exists in your venv bin folder you can find it with sudo find / -name bpython. In my case it got installed in ~/.local/bin/

$ source alchemy/bin/activate
$ pip install bpython
...
$ ~/.local/bin/bpython
