pip安装在TypeError中失败: identify()获得了一个意外的关键字参数'requirement_or_candidate‘

Question

最近，我使用从下到顶的方法将我的arch linux安装移到了一台新机器上。即重新安装arch linux，重新安装所有包，然后将选定的信任复制到新机器上。

现在，当我尝试使用pip安装程序时，我得到了如下所示的TypeError：

ERROR: Exception:

    status = self.run(options, args)

    name = self._p.identify(requirement_or_candidate=requirement)
TypeError: identify() got an unexpected keyword argument 'requirement_or_candidate'

通过sudo作为root安装实际上是有效的(我知道我不应该这样做，只是为了测试。因此，我认为，这肯定是由于许可问题，或在团体方面遗漏了一些东西。

谁能给我指明正确的方向？我是否需要将我的用户添加到某个组？

谢谢

您在resolvelib上有一个本地安装的库/home/mor3dr3ad/.local/lib/python3.9/site-packages/resolvelib/。它似乎与pip在/usr/lib/python3.9/site-packages/pip/_internal/resolution/resolvelib/和/usr/lib/python3.9/site-packages/pip/_vendor/resolvelib/上提供的resolvelib不兼容。

我的建议是卸载本地resolvelib。试一试

pip uninstall resolvelib

PS。很可能是sudo工作，因为它将用户切换到root，并且用户在/root/.local/lib/上没有本地包
