Question or problem about Python programming:
I set up a virtualenv environment on my Mac, but cannot get Pip to install packages. It fails with the following error:
/Volumes/Macintosh: bad interpreter: No such file or directory
I tracked the problem down to there being a space in the path, as is answered here: https://stackoverflow.com/a/10873611/126564
(the path being /Volumes/Macintosh HD/Python/my_project)
But that’s a bit of a problem. The proposed solution is to:
but the part with the space is the volume itself. All of my paths would have a space, unless I stored them in a directory of /. And I don’t think “store your stuff outside of user space” is a good solution.
Is there a better solution to this?
How to solve the problem:
VIRTUAL_ENV='/Volumes/Macintosh HD/Python/my_project', and change
PATH="$VIRTUAL_ENV/bin:$PATH", to make it work in your environment. using
echo $PATHto check if it works.
bin/easy_install, change first line in the two files to
After above 2 steps, you’ll make your virtualenv works(also pip/easy_install).
Note that you don’t have to use your project folder for virtualenv. For example, you can place your virtualenv into /tmp folder or any other folder without spaces:
virtualenv /tmp/temporary_virtualenv virtualenv /home/my_envs/env_for_projectname
I have yet another workaround – you just need to use
pip package instead of
pip script. For example:
python -m pip install .
python -m pip install -U pip
For me works like a charm and doesn’t require changes in files.
bin/activate file and escaping the spaces worked for me.
Edit and save the file, then run
Unless you have an atypical drive setup on your Mac, the path
/Volumes/Macintosh HD should be a symlink to
/. In other words, instead of
$ virtualenv /Volumes/Macintosh\ HD/venvpath
you can just do
$ virtualenv /venvpath
Not that I’m trying to condone software not handling spaces in file names. I agree with Hugo’s comment above: keep an eye on the relevant GitHub issue.
As of end of 2018 the latest versions of
virtualenv deal with spaces in venv dir correctly.
