Error installing with pip within virtualenv on raspberry pi: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/lib/python2.7/site-packages'

[harryjjacobs]

When trying to install the latest version of pocketsphinx (or any for that matter) via pip (pip install pocketsphinx) whilst inside a virtualenv I get this error:

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/lib/python2.7/site-packages'
Consider using the `--user` option or check the permissions.

I've also tried installing it from source without pip and it still seems to be trying to install itself in the global /usr/lib/python2.7/site-packages directory rather than in the venv.
Any ideas?

this error want to tell you, it has gone change os directory and its need your permission to do that and for that, you need to use these command pip install <package> --user or sudo python(x) -m pip install <package> but for avoiding to do that you must create venv and then if your venv was activated you never get that error if you see that error and you working in venv you might need to activate venv
