Elpy: /usr/bin/pythonw is used even if a virtualenv is activated

[rakanalh]

Hello,

On the most recent version of elpy on melpa, elpy is not detecting installed dependencies such as jedi, yapf .. etc.

Am not sure if you latest commit (https://github.com/jorgenschaefer/elpy/commit/2d6dc9f31de8805f2b7630c874942fb7e8fb5bd3) causes this or not but i find it weird that /usr/bin/pythonw is used as the version i am using with pyenv is 3.6.2 as apparent on the screenshot.

Edit: The issue is resolved by

(setq elpy-rpc-python-command "~/.pyenv/versions/x/bin/python")

My pyenv doesn't contain pythonw or py executables so maybe virtualenvs should have a different lookup priority?

Thanks

Same problem here.

@rakanalh Yes you're right, must be that commit.
On OS X /usr/bin/pythonw is available. Because the system-type check is removed in this commit the rpc-python is set to pythonw.

Same problem here. In virtualenv, elpy would find the system-wide pythonw, and will not find packages installed in the virtualenv anymore.

Comment out commit 2d6dc9f31de8805f2b7630c874942fb7e8fb5bd3 fixes this problem. In elpy-config, it will find the correct "RPC Python" as in the virtualenv.

I feel elpy-config and clean code structure have made my debugging experience very pleasant. I almost found the source of bug under 2 minutes. Nice job!

@jorgenschaefer seems like multiple people are having this issue... could you please consider a fix? we can revert the commit if you're ok with that approach.

+1 here, too.

… wtf is pythonw available anywhere but Windows? Why is Windows such a pain? :-D Sorry for the inconvenience. As a workaround, you can (setq elpy-rpc-python-command "python") and things should work out. I'm currently without sensible internet access, so I'll not get around to a real fix until later I'm afraid.

I'm using Mac. So the system does have a pythonw, but the one in virtualenv doesn't. That's causing the problem. elpy finds the outside pythonw even if I'm in virtualenv.

I just pushed 90c659e – does that fix this problem?

[igroen]

@jorgenschaefer 90c659e fixes this bug on OS X. Thanks for your quick fix.

[rakanalh]

Yup... the fix works... thanks @jorgenschaefer
