Answer 1

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

(还没有内置标志，但是您可以使用)

pip list --outdated --format=freeze | grep -v '^-e' | cut -d = -f 1  | xargs -n1 pip install -U

Note: there are infinite potential variations for this.

(注意：为此存在无限的潜在变化。)

I'm trying to keep this answer short and simple, but please do suggest variations in the comments!

(我试图使这个答案简短而简单，但是请在评论中提出一些建议！)

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

(在旧版本的pip ，您可以改用以下命令：)

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

The grep is to skip editable ("-e") package definitions, as suggested by @jawache.

(grep将跳过@jawache建议的可编辑（“ -e”）软件包定义。)

(Yes, you could replace grep + cut with sed or awk or perl or...).

(（是的，您可以将grep + cut替换为sed或awk或perl或...）。)

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

(如果更新一个软件包失败（感谢@andsens ），则xargs的-n1标志可阻止停止所有操作。)
