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

Option a) Create a virtualenv, activate it and install:

virtualenv .venv
source .venv/bin/activate
pip install -r requirements.txt

Option b) Install in your homedir:

pip install --user -r requirements.txt

My recommendation use safe (a) option, so that requirements of this project do not interfere with other projects requirements.
