OS: macOS Sierra Beta 6 Python: 2.7 Shell: Fish

I am having issues with my PYTHONPATH environmental variable being set correctly.

In my fish_config file, I have this line setting up PYTHONPATH:

set -gx PYTHONPATH "/opt/additionalPath" "/usr/local/lib/python2.7/site-packages";

But when I launch python, I get this output when I try to look at the path:

>>> import sys
>>> print sys.path
['', '/opt/additionalPath\x1e/usr/local/lib/python2.7/site-packages', '/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages', '/Library/Python/2.7/site-packages']

Notice the \x1e between the paths that I am adding.

If I launch the bash shell from fish and echo $PYTHONPATH, I get this output:


I know that those paths are supposed to be separate by a colon but I can't figure out where that is being done. My theory is that something in the bash shell is setting the path in the fish shell but I am running out of ideas.

Any help would be much appreciated.

You can't use a list in fish for PYTHONPATH, you have to use a single string with : as a separator as you would do in bash:

set -gx PYTHONPATH "/opt/additionalPath:/usr/local/lib/python2.7/site-packages"

See this bug report for some more info.

  • Also, if you're using fish 2.3.0 or newer, and thus can use the new string builtin, you can do it this way: set -gx PYTHONPATH (string join : /opt/additionalPath /usr/local/lib/python2.7/site-packages) – Kurtis Rader Aug 19 '16 at 21:37
