I am trying to install Pandas with pip, but ran into to a problem. Here are the details:

Mac OS Sierra

which python => /usr/bin/python

python --version => Python 2.7.10

Inside "/System/Library/Frameworks/Python.framework/Versions" there is the following

2.3 2.5 2.6 2.7 Current

I want pandas to be linked to Python 2.7.10 in "/usr/bin/python"

When I do pip install pandas, I get the following error message:

Thanks for helping.

Try running the pip install command as sudo.

sudo pip install pandas

Python packages are installed in the operating systems file system where not all users have permission to write files to. This is why you need to run the command as sudo, as sudo elevates your privileges to do this.

Edit: This seems to be getting some upvotes so I've added some clarity to this question regarding user specific installation. You can also install this just for your user should this fit your use case with: pip install --user pandas.
