我正在尝试安装一个从github下载的项目：

安装失败的原因如下：

File "/usr/lib/python3.9/distutils/util.py", line 9, in <module>
        import importlib.util
    ModuleNotFoundError: No module named 'importlib.util'

importlib是python3.9的一部分，因此它不会失败。
实际上，当我启动Python3 shell时，我可以导入该模块：

Python 3.9.2 (default, Feb 28 2021, 17:03:44) 
[GCC 10.2.1 20210110] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import importlib.util
>>>

另外，我不明白这句话：

Collecting importlib<1.1.0,>=1.0.4
  Using cached importlib-1.0.4.zip (7.1 kB)

所有其他依赖项都在requirement.txt中，但不在importlib中：

torch~=1.13.1
openai-whisper~=20230124
streamlit~=1.18.1
streamlit_player~=0.1.5
streamlit-aggrid~=0.3.3
ffsubsync~=0.4.23
git+https://github.com/linto-ai/whisper-timestamped
pandas~=1.5.2
pysubs2~=1.6.0

现在，这一行可能是相关的：

importlib~=1.0.4

在上游存储库中存在。但是安装时抛出了与现在相同的错误。

更新：我还删除了pyproject.toml和poetry.lock中的所有引用，但我没有将其包含在我的原始帖子中。
因此，我克隆了这个项目，并从requirements.txt中删除了对importlib~=1.0.4的引用。
为什么pip仍然坚持安装它，为什么它失败了，而当我在Python3 shell中执行相同的导入时，它成功了。
环境：Debian 11靶心
pip 20.3.4来自于/usr/lib/python3/dist-packages/pip（Python 3.9）
