I'm trying to safely install PyMySQL. I've read many good arguments about why sudo pip install should be avoided, but sometimes it just seems impossible to get away from.
Is there a way to install PyMySQL locally in OSX without using sudo?
(VirtualEnv) : ^.^ :pip install --no-cache-dir --user PyMySQL

To install within a virtual env run this command.
pip install --install-option="--prefix=/Users/TomNason/VirtualEnv/lib/python2.7" PyMySQL
Generally- if you cannot install PyMySQL with pip inside a virtual environment (even if you are using the --user option) you can try...
pip install --install-option="--prefix=PATH_TO_YOUR_VIRTUAL_ENV_DIR/lib/PYTHON_VERSION" PyMySQL
This is still a curious situation for me. Any comments on why I would have to explicitely state my python directory are welcome. I thought that the reason for using a virtual environment was that pip will always choose to install there.
Here is the error I'm seeing. Is there something wrong in my install? Any help would be appreciated.

Its a Mac OSX permission related problem. If you search for OSError: [Errno 1] Operation not permitted: you will find possible resolutions, favourites being:
brew install python
or
pip install --ignore-installed six
or using virtualenv
There is an entire discussion about this here : Six issue when installing package
The solution that worked for me is :
sudo pip install watson-developer-cloud --upgrade --ignore-installed six

I am using macOS Sierra 10.12.5. I downloaded pip using sudo easy_install pip.
Any guidance on this? Thanks.
One of the way (may be not the simpler) is to install anaconda.
https://www.continuum.io/downloads#macos
I don't believe you need only pandas ))
Anaconda contains pandas and a lot of packages that you'll definately need in your ML practice.

At a glance it looks like you need admin permissions to install packages on your system. Try starting pip as admin:
sudo pip install virtualenv
