Alternatively  if you want to install specific version of the package with the specific version of python  this is the way   sudo python2 7 -m pip install pyudev 0 16   if the     doesnt work  use     x ubuntuserv    sudo python2 7 -m pip install pyudev 0 16  Invalid requirement   pyudev 0 16    is not a valid operator  Did you mean       x ubuntuserv    sudo python2 7 -m pip install pyudev  0 16  works fine

Use a version of pip installed against the Python instance you want to install new packages to   In many distributions  there may be separate python2 6-pip and python2 7-pip packages  invoked with binary names such as pip-2 6 and pip-2 7  If pip is not packaged in your distribution for the desired target  you might look for a setuptools or easyinstall package  or use virtualenv  which will always include pip in a generated environment    pip s website includes installation instructions  if you can t find anything within your distribution

If you have both 2 7 and 3 x versions of python installed  then just rename the python exe file of python 3 x version to something like -  python exe  to  python3 exe   Now you can use pip for both versions individually  If you normally type  pip install   it will consider the 2 7 version by default  If you want to install it on the 3 x version you need to call the command as  python3 -m pip install
