I am missing something obviously simple here, but I can't say what : I need your fresh eyes to tell me :)

$ pip install python-dateutil
Requirement already satisfied (use --upgrade to upgrade): python-dateutil in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
Cleaning up...
$ python

How to import dateutils ??

回答1:

The root cause might be that python and pip do not match.

You can check their versions.

pip -V
python -V
pip2 -V

As you can see, python and pip do not match. pip is for python3 and python is for python2.

Hence, the solution should be

pip2 install python-dateutil
