[PYTHON] I got stuck trying to install various things with Mac El captain pip, so make a note

El capitan's python directory is / usr / bin, so let's go !! (Higanjima)

When I tried to install with pip such as Jupyter and Tensorflow after changing the OS of Mac to El captain, I got many errors that I had never seen.

    DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

When I tried which python, the python attached to the OS was directly under / usr / bin /, and this seems to be the cause. After reinstalling python with brew, python fits in / usr / local / bin and all subsequent installations worked.

brew update
brew install python
which python
/usr/local/bin/python

After that, when I tried to insert ggplot2 and rjags in R, I got the following error.

Warning message:

I have done the following with reference to here.

sudo ln -s /usr/X11 /opt/X11 
locate libSM.6.dylib
