pip freeze shows me the packages installed, but how do I check against pypi which ones are outdated?
Since version 1.3, pip features a new command:
$ pip list --outdated requests (Current: 1.1.0 Latest: 1.2.0)
See this post for more information.
Thing is, I never upgrade all packages. I upgrade only what I need, because projects may break.
Because there was no easy way to upgrade package by package and update the requirements.txt file, I wrote pip-upgrader which also updates the versions in your
requirements.txt file for the packages chosen (or all packages).
pip install pip-upgrader
Activate your virtualenv (important, because it will also install the new versions of upgraded packages in the current virtualenv).
cd into your project directory, then run:
If the requirements are placed in a non-standard location, send them as arguments:
If you already know what package you want to upgrade, simply send them as arguments:
pip-upgrade -p django -p celery -p dateutil
If you need to upgrade to pre-release / post-release version, add
--prerelease argument to your command.
Full disclosure: I wrote this package.
Perhaps pip-tools, available at https://github.com/nvie/pip-tools, might help you achieve what you want?
An example from the README:
$ pip-review --interactive requests==0.14.0 available (you have 0.13.2) Upgrade now? [Y]es, [N]o, [A]ll, [Q]uit y ... redis==2.6.2 available (you have 2.4.9) Upgrade now? [Y]es, [N]o, [A]ll, [Q]uit n rq==0.3.2 available (you have 0.3.0) Upgrade now? [Y]es, [N]o, [A]ll, [Q]uit y ...
Use this pip fork:
Which does exactly what you want using this command:
$ pip list --outdated
pip list --outdated
See also docs on
pip install pip-check pip-check
pip list --outdated but updates a
pur -r requirements.txt
Or you can
pip list --o
List installed packages, including editables. pip list
