如何修复 python3.10 上的 importlib 以便它可以正确调用 entry_points()？

Question

我在 Ubuntu 22.04 上使用 Python 3.10 从事一个使用 Farama Foundation 的 gymnasium 图书馆 的项目。导入gymnasium时，它使用importlib获取entry points，但是当我将

import gymnasium

运行到IDLE时，出现以下错误：

Traceback (most recent call last):
  File "/usr/lib/python3.10/idlelib/run.py", line 578, in runcode
    exec(code, self.locals)
  File "<pyshell#2>", line 1, in <module>
  File "/usr/local/lib/python3.10/dist-packages/gymnasium/__init__.py", line 12, in <module>
    from gymnasium.envs.registration import (

    for plugin in metadata.entry_points(group=entry_point):
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 1009, in entry_points
    return SelectableGroups.load(eps).select(**params)
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 459, in load
    ordered = sorted(eps, key=by_group)
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 1006, in <genexpr>
    eps = itertools.chain.from_iterable(
  File "/usr/lib/python3.10/importlib/metadata/_itertools.py", line 16, in unique_everseen
    k = key(element)
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 941, in _normalized_name
    return self._name_from_stem(stem) or super()._normalized_name
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 622, in _normalized_name
    return Prepared.normalize(self.name)
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 871, in normalize
    return re.sub(r"[-_.]+", "-", name).lower().replace('-', '_')
  File "/usr/lib/python3.10/re.py", line 209, in sub
    return _compile(pattern, flags).sub(repl, string, count)
TypeError: expected string or bytes-like object

我在 GitHub 上向 gymnasium 的一位创建者询问了这个问题，他们要求我打印出入口点列表，所以我运行了以下命令：

from importlib.metadata import *
eps = entry_points()

并得到以下错误：

Traceback (most recent call last):
  File "/usr/lib/python3.10/idlelib/run.py", line 578, in runcode
    exec(code, self.locals)
  File "<pyshell#1>", line 1, in <module>

    return SelectableGroups.load(eps).select(**params)
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 459, in load
    ordered = sorted(eps, key=by_group)
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 1006, in <genexpr>
    eps = itertools.chain.from_iterable(
  File "/usr/lib/python3.10/importlib/metadata/_itertools.py", line 16, in unique_everseen
    k = key(element)
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 941, in _normalized_name
    return self._name_from_stem(stem) or super()._normalized_name
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 622, in _normalized_name
    return Prepared.normalize(self.name)
  File "/usr/lib/python3.10/importlib/metadata/__init__.py", line 871, in normalize
    return re.sub(r"[-_.]+", "-", name).lower().replace('-', '_')
  File "/usr/lib/python3.10/re.py", line 209, in sub
    return _compile(pattern, flags).sub(repl, string, count)
TypeError: expected string or bytes-like object

这似乎表明

entry_points()

正在搜索的其中一个名称的格式不正确。我不确定如何解决这个问题。我愿意完全卸载 Python 3.10 并从头开始重新安装它和所有其他软件包，但我更喜欢一种不那么激进的方法。
