I recently switched a project over to using virtualenv for my PyCharm Django server run/debug configuration and ran into a ‘command not found’ error when trying to use another MacPorts installed package (sass) from Django (via Django Compressor).
Here is my original server configuration in PyCharm:
A quick look at the PATH environment variable identified the trouble:
MacPorts Python (/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7)
>>> print os.environ['PATH']
/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
Virtualenv Python (/Users/chriskief/.virtualenvs/exampleproject/bin/python)
>>> print os.environ['PATH']
/usr/bin:/bin:/usr/sbin:/sbin:/Users/chriskief/.virtualenvs/exampleproject/bin
The MacPorts bin and sbin are missing from the PATH, and that’s where sass lives:
which sass
/opt/local/bin/sass
The solution is to add the MacPorts directories (/opt/local/bin:/opt/local/sbin:$PATH) to your environment variables’ PATH in the run/debug configuration:
As a side note, if you run the Django server using the virtualenv from your terminal, you won’t encounter this error because MacPorts includes these directories in your .profile PATH:
# MacPorts Installer addition on 2013-10-26_at_16:30:30: adding an appropriate PATH variable for use with MacPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
# Finished adapting your PATH environment variable for use with MacPorts.
