pip permissions with Fabric

I'm trying to use Fabric via SSH to run pip install, but get the following traceback:

Exception:

    mkdir(name, mode)

I don't get this error when manually ssh-ing into PA and running the command. I'm not that familiar with how user permissions factor into this - what should I do?

Ok, found that I had to use the pip from the virtualenv, not sure why though?

Do you need to workon myenv before trying to do things in your virtualenv?

Hmm I had this previously:

run('workon {virtualenv}'.format(...))
run('pip install -r {site_folder}/requirements.txt'.format(...))

Do I need to run them together with &&?

Yes, the two "run" commands won't share state between each other. Using the path to the virtualenv pip may be neater...

Thanks Harry - how would I get the environment variables from my postactivate file?

I'm using virtualenvwrapper, not sure if that's contributing to the problems.

I had asked something similar where I needed to add source virtualenvwrapper.sh, but it seems like it doesn't help.

source virtualenvwrapper.sh && workon thing && pip install stuff should work... what's going wrong?

Staff harry | 2710 posts | PythonAnywhere staff | March 22, 2017, 6:15 p.m. | permalink

Found the reason - my stupidity. I forgot --settings with manage.py.

Thanks Harry!
