（Python）ModuleNotFoundError：没有名为“pip._vendor.progress”的模块

Question

当我尝试安装最新的discord.py版本时，出现此错误：

  File "C:\Users\44794\AppData\Local\Programs\Python\Python38\lib\runpy.py", line 194, in _run_module_as_main

    from pip._vendor.progress.bar import Bar, FillingCirclesBar, IncrementalBar
ModuleNotFoundError: No module named 'pip._vendor.progress'

我是Python之类的新手，所以请不要全是技术性的。假设你正在和一个四岁的孩子说话。预先感谢。
