How to see pip package sizes installed?

Could please try this one(A bit long though, maybe there are better solutions):

$ pip list | xargs pip show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{print $2 "/" tolower($1)}' | xargs du -sh 2> /dev/null

the output should look like this:

80K     /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/blinker3.8M    /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/docutils296K    /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/ecdsa340K    /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/execnet564K    /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/fabric1.4M    /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/flask316K    /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/httplib21.9M    /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/jinja2...

should works if the package is installed in Location/Name. (location and name are from pip show <package>)

pip show <package> will show you the location:

---Metadata-Version: 2.0Name: FlaskVersion: 0.10.1Summary: A microframework based on Werkzeug, Jinja2 and good intentionsHome-page: http://github.com/mitsuhiko/flask/Author: Armin RonacherAuthor-email: armin.ronacher@active-4.comLicense: BSDLocation: /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packagesRequires: itsdangerous, Werkzeug, Jinja2

we get the Name and Location to join them to get the location, finally use du -sh to get the package size.

New version for new pip list format:

pip2 list --format freeze|awk -F = {'print $1'}| xargs pip2 show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{print $2 "/" tolower($1)}' | xargs du -sh 2> /dev/null|sort -h

Modified for pip version 18 and above:

pip list | tail -n +3 | awk '{print $1}' | xargs pip show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{print $2 "/" tolower($1)}' | xargs du -sh 2> /dev/null | sort -hr

This command shows pip packages, sorted by descending order of sizes.
