如何使用 pip 升级所有 Python 包

是否可以使用 pip 一次升级所有 Python 包 ?

The following works on Windows and should be good for others too ($ is whatever directory you're in, in the command prompt. For example, C:/Users/Username).

Do

$ pip freeze > requirements.txt

Open the text file, replace the == with >=, or have sed do it for you:

$ sed -i 's/==/>=/g' requirements.txt

and execute:

$ pip install -r requirements.txt --upgrade

If you have a problem with a certain package stalling the upgrade (NumPy sometimes), just go to the directory ($), comment out the name (add a # before it) and run the upgrade again. You can later uncomment that section back. This is also great for copying Python global environments.


Another way:

I also like the pip-review method:

py2
$ pip install pip-review

$ pip-review --local --interactive

py3
$ pip3 install pip-review

$ py -3 -m pip-review --local --interactive

You can select 'a' to upgrade all packages; if one upgrade fails, run it again and it continues at the next one.

Use pipupgrade!

$ pip install pipupgrade
$ pipupgrade --verbose --latest --yes

pipupgrade helps you upgrade your system, local or packages from a requirements.txt file! It also selectively upgrades packages that don't break change.

pipupgrade also ensures to upgrade packages present within multiple Python environments. It is compatible with Python 2.7+, Python 3.4+ and pip 9+, pip 10+, pip 18+, pip 19+.

Note: I'm the author of the tool.

You can just print the packages that are outdated:

pip freeze | cut -d = -f 1 | xargs -n 1 pip search | grep -B2 'LATEST:'

Use AWK update packages:

pip install -U $(pip freeze | awk -F'[=]' '{print $1}')

Windows PowerShell update

foreach($p in $(pip freeze)){ pip install -U $p.Split("=")[0]}
