推荐答案

尚无内置标志，但您可以使用

There isn't a built-in flag yet, but you can use

pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U

注意:为此存在无限的潜在变化.我试图使这个答案简短而简单，但请在评论中提出一些建议！

Note: there are infinite potential variations for this. I'm trying to keep this answer short and simple, but please do suggest variations in the comments!

在pip的旧版本中，您可以改用此:

In older version of pip, you can use this instead:

pip freeze --local | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U

grep将跳过@jawache建议的可编辑("-e")软件包定义. (是的，您可以将grep + cut替换为sed或awk或perl或...).

The grep is to skip editable ("-e") package definitions, as suggested by @jawache. (Yes, you could replace grep+cut with sed or awk or perl or...).

xargs的-n1标志可防止在更新一个软件包失败时停止所有操作(感谢 @andsens ).

The -n1 flag for xargs prevents stopping everything if updating one package fails (thanks @andsens).
