Cannot uninstall ‘six’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall

Installing Mechanize gives error on MacOS Mojave For Python and Pip 2.7 This error is due to a version of ‘six’ which comes default with MacOS

Use the below command to ignore the version of six installed and install mechanize

$ pip2.7 install mechanize –ignore-installed six –user
