我最近使用自下而上的方法将我的 Arch linux 安装移动到了一台新机器上。即新安装arch linux，重新安装所有软件包，然后将选定的配置复制到新机器上。

现在，当我尝试使用 pip 安装程序时，我得到一个 TypeError，如下所示：

ERROR: Exception:
Traceback (most recent call last):
  File "/usr/lib/python3.9/site-packages/pip/_internal/cli/base_command.py", line 224, in _main
    status = self.run(options, args)

    return func(self, options, args)
  File "/usr/lib/python3.9/site-packages/pip/_internal/commands/install.py", line 320, in run
    requirement_set = resolver.resolve(
  File "/usr/lib/python3.9/site-packages/pip/_internal/resolution/resolvelib/resolver.py", line 121, in resolve
    self._result = resolver.resolve(
  File "/home/mor3dr3ad/.local/lib/python3.9/site-packages/resolvelib/resolvers.py", line 454, in resolve
    state = resolution.resolve(requirements, max_rounds=max_rounds)
  File "/home/mor3dr3ad/.local/lib/python3.9/site-packages/resolvelib/resolvers.py", line 319, in resolve
    name, crit = self._merge_into_criterion(r, parent=None)
  File "/home/mor3dr3ad/.local/lib/python3.9/site-packages/resolvelib/resolvers.py", line 171, in _merge_into_criterion
    name = self._p.identify(requirement_or_candidate=requirement)
TypeError: identify() got an unexpected keyword argument 'requirement_or_candidate'

通过 sudo 以 root 身份安装实际上可以工作（我知道我不应该这样做，只是为了测试。所以我认为这一定是由于权限问题或在组方面缺少某些东西。

谁能指出我正确的方向？我需要将我的用户添加到某个组吗？

谢谢

您有一个本地安装的库resolvelib，位于/home/mor3dr3ad/.local/lib/python3.9/site-packages/resolvelib/. 它似乎与pipvendored resolvelibat /usr/lib/python3.9/site-packages/pip/_internal/resolution/resolvelib/and不兼容/usr/lib/python3.9/site-packages/pip/_vendor/resolvelib/。

我的建议是卸载本地resolvelib. 尝试

pip uninstall resolvelib

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