Python 2.7 traceback error in sublime. Wrong version of python

Question

I'm getting this error in sublime. Even though it says 2.7, I thought I installed 3.5.2. I looked at the directory and can find no files that shouldn't be there.

   Traceback (most recent call last):
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)

I have no idea how to start debugging this error.

Answer 1

Type the following command in your terminal to see the location of Python 3.5:

which python3.5

You might also want to add the following shebang to your script:

#!/usr/bin/env python3.5

HTH.

Answer 2

You may not have sublime configured to use python 3. You can address this by using the shebang mentioned above, or by configuring sublime (looks like this is how https://forum.sublimetext.com/t/select-which-version-of-python-to-run-build/1695/8 ).

If you installed python3 using MacPorts (that is what I did), then you should note that it may not be in the normal env search paths. If so, you can check which python3 ports you have installed and where their python executable is with:

port echo python3* and active and not python3_select | cut -d' ' -f1 | while read pn; do echo "$pn: $(port contents $pn | grep -E '/opt/local/bin/python.*[0-9]$')"; done

And this should give you a result like:

python34:   /opt/local/bin/python3.4
python35:   /opt/local/bin/python3.5

Which you can then use in your shebang like

#!/opt/local/bin/python3.5
