问题
I am trying to install Sphinx on OSX, with the hopes of eventually making it into a website, following this guide :
I have been macporting, homebrewing, python wheelin', figuring out what a virtualenv is... figuring out if I should use python 2.7 or 3.X (which I couldn't figure out)
I added this to my bash profile :
export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages
When I run this :
python -c "import sys; print('\n'.join(sys.path))"
I had expected it to return simply /usr/local/lib/python2.7/site-packages
but it says the following :
/Library/Python/2.7/site-packages/pip-10.0.0b2-py2.7.egg
/Library/Python/2.7/site-packages/virtualenv-15.2.0-py2.7.egg
/Users/nook
/usr/local/lib/python2.7/site-packages
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload
/Users/nook/Library/Python/2.7/lib/python/site-packages
/Library/Python/2.7/site-packages
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
Anyway, I finally got a virtualenv set-up, and ran the following command:
pip install sphinx
I sorted out a NumPy error, and another error with six. But I am unable to get rid of the following error :
jupyter-client 5.2.3 has requirement python-dateutil>=2.1,
but you'll have python-dateutil 1.5 which is incompatible.
When I run the following command :
pip install python-dateutil --upgrade --ignore-installed
I get
Collecting python-dateutil
Using cached python_dateutil-2.7.2-py2.py3-none-any.whl
Collecting six>=1.5 (from python-dateutil)
Using cached six-1.11.0-py2.py3-none-any.whl
Installing collected packages: six, python-dateutil`
That seems good...
But when I try to install sphinx again I get the same
jupyter-client 5.2.3 has requirement python-dateutil>=2.1, but you'll have
python-dateutil 1.5 which is incompatible.
So I went in and tried the following command :
sudo rm -rf /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/python_dateutil-1.5-py2.7.egg-info/
I want to remove that directory, to NumPy directories, and another dateutil directory...but can't ! I don't have the permissions.
If anyone has a pro-tip on what version of python to use for my sphinx site (the latest version ?), and how set up a virtual environment with **that version of python, figure out Numpty and dateutil... I will be forever in your debt !
EDIT : Just tried the following :
sudo pip install python-dateutil

Requirement already satisfied: python-dateutil in
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
(1.5)
pandas 0.22.0 has requirement numpy>=1.9.0, but you'll have numpy 1.8.0rc1
which is incompatible.
matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1
which is incompatible.
jupyter-client 5.2.3 has requirement python-dateutil>=2.1, but you'll have
python-dateutil 1.5 which is incompatible.
You can see my numpy is totally budget too, at 1.8.0rc1. Thanks.
