Question

请多多指教，谢谢:)

pip list --outdated --format=freeze

出现以下错误：

Answer 1

不是修复，而是某种解决方案：

我'fixed'通过更新每个包来做到这一点。

for f in `pip list | tail -n +3 | cut -d' ' -f1`; do
    pip install --update "$f";
done

我在以 root 身份登录并升级到 Debian 11 后立即发现了 OP 的问题；不知道这是否重要。

Answer 2

我更新 pip 解决了这个问题，我从 pip 20.3.4 更新到 21.3 所以只需输入：

pip install pip -U

似乎 pip 本身存在一些错误。

Answer 3

我在 in the Debian bugtracker 中对这个错误做了一些分析。

它似乎是由 Debian 直到最近打包 pip 的方式引发的 race-condition。依赖项是从 wheels zip 导入的，而不是像上游那样在源代码树中出售。

这应该已经在 Debian >= 12 (bookworm) 和 Ubuntu >= 22.04 (jammy) 中解决了。

Debian 11（靶心）中 pip 的更新是 in progress。
