pip install failing with: OSError: [Errno 13] Permission denied on directory

Question

pip install -r requirements.txt fails with the exception below OSError: [Errno 13] Permission denied: \'/usr/local/lib/.... What\'s wrong and how d

Answer 1

It is due permission problem,

sudo chown -R $USER /path to your python installed directory

default it would be /usr/local/lib/python2.7/

or try,

pip install --user -r package_name

and then say, pip install -r requirements.txt this will install inside your env

dont say, sudo pip install -r requirements.txt this is will install into arbitrary python path.
