Pip 将包列为已过时但已满足要求的更新结果

Question

使用sudo pip install -U <package>

解决

所以当我 pip list --outdated 我得到：

Package           Version     Latest Type

anyio             3.3.3       3.3.4  wheel

trimesh           3.9.31      3.9.32 wheel
websocket-client  0.59.0      1.2.1  wheel

然后当我 pip install anyio -U 更新第一个包时，我得到：

Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: anyio in ./.local/lib/python3.9/site-packages (3.3.4)
Requirement already satisfied: idna>=2.8 in ./.local/lib/python3.9/site-packages (from anyio) (3.3)
Requirement already satisfied: sniffio>=1.1 in /usr/lib/python3.9/site-packages (from anyio) (1.2.0)

据我所知，该软件包已经更新，但 pip 仍将该软件包列为已过时，也未将其列在更新的软件包列表中。

这是怎么回事？

Answer 1

请参阅 this，您可以猜到这里的问题是 Defaulting to user installation because normal site-packages is not writeable，它涉及一些我不确定的权限相关问题。

你可以在这里使用 python3 -m pip install -U <package>.

A stable solution could be to reinstall python from scratch in your system.
