installation - error: could not create '/Library/Python/2.7/site-packages/xlrd': Permission denied

Question

I'm trying to install xlrd on mac 10.8.4 to be able to read excel files through python.

I have followed the instructions on http://www.simplistix.co.uk/presentations/python-excel.pdf

I did this:

1. unzipped the folder to desktop

2. in terminal, cd to the unzipped folder

3. $ python setup.py install

This is what I get:

running install

running build_py

error: could not create '/Library/Python/2.7/site-packages/xlrd': Permission denied

Why is permission denied? Thanks

Try python setup.py install --user

You shouldn't use sudo as suggested above for two reasons:

1. You're allowing arbitrary untrusted code off the internet to be run as root
2. Passing the --user flag to python setup.py install will install the package to a user-owned directory. Your normal non-root user won't be able to access the files installed by sudo pip or sudo python setup.py
