由于 urllib3 无法安装 Python 包

Question

我正在尝试运行Python脚本：

python main.py

获得此输出：

Traceback (most recent call last):
  File "main.py", line 8, in <module>
    import stateful
  File "/path/to/s.py", line 599, in <module>
    import policy as offloading_policy
  File "/path/to/p.py", line 2, in <module>
    from pacsltk import perfmodel
ModuleNotFoundError: No module named 'pacsltk'

Process finished with exit code 1

...但不仅已经安装了

pacsltk

：当我尝试安装它时（

pip install pacsltk

），我得到：

此外，当我尝试运行建议的命令

pip install --force-reinstall --no-deps urllib3==2.0.4

时，我只能获得相同的错误：

尝试

pip uninstall urllib3

时出现类似错误。 另外，

sudo apt-get autoremove

/

purge

应用于

python-urllib3

只是表示该软件包未安装。

与

urllib3

相同的错误似乎适用于我想要安装的任何 python 包。我已经查看了其他几个存在此错误的问题，但没有解决这个问题。我能做什么？

Answer 1

python 和 pip 包似乎已损坏。尝试以下方法：

1. 卸载系统上安装的任何 python 或 pip 包
2. 重新安装 python 和 pip 以及所有包和模块。

让我知道它是否有效。 我安装了“scratch”，但遇到了完全相同的错误。然后我这样做了，它运行顺利。
