Trying to install lib which is pre-requisite to run my automation code, observe below error :

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/futures-3.2.0.dist-info'

My environment :

  • MAC : 10.14
  • 1
    Either use sudo or a virtual environment

You either go with creating a Python virtual environment as suggested by Ernie.

Or you can use pip install's --user option to install packages into your home directory where you have all required permissions. E.g.:

pip install myPackage --user

Do not forget to add the install directory in your home to PATH environment variable.


You can also try

source anaconda3/bin/activate 

and then run

 pip3 install <package-name>

Worked for me.
