卸载的wrapt模块：Python不工作

Question

由于wrapt的ModuleNotFoundError导致安装包时遇到困难，因此我删除并尝试重新安装wrapt

我运行了一次卸载，wrapt从一个位置被删除。我试图安装，但需求已经满足，所以我再次卸载了wrapt。请参见下面的三个命令：

Found existing installation: wrapt 1.12.1
Uninstalling wrapt-1.12.1:
  Would remove:
    c:\users\me\appdata\roaming\python\python38\site-packages\wrapt-1.12.1-py3.8.egg-info
    c:\users\me\appdata\roaming\python\python38\site-packages\wrapt\*
Proceed (y/n)? y
  Successfully uninstalled wrapt-1.12.1
PS C:\Users\me> pip install wrapt
Requirement already satisfied: wrapt in c:\users\me\appdata\local\programs\python\python38\lib\site-packages (1.12.1)
PS C:\Users\me> pip uninstall wrapt
Found existing installation: wrapt 1.12.1
Uninstalling wrapt-1.12.1:
  Would remove:
    c:\users\me\appdata\local\programs\python\python38\lib\site-packages\wrapt-1.12.1.dist-info\*
    c:\users\me\appdata\local\programs\python\python38\lib\site-packages\wrapt\*
Proceed (y/n)? y
  Successfully uninstalled wrapt-1.12.1

我以为我已经准备好从头开始，但没有这样的运气。现在，每当我尝试运行python或pip时，都会收到以下错误

Fatal Python error: init_import_size: Failed to import the site module
Python runtime state: initialized
Traceback (most recent call last):

    import wrapt
ModuleNotFoundError: No module named 'wrapt'

我曾尝试寻找不使用pip的wrapt安装，但没有成功。我还尝试将Python从3.8.1升级到3.8.3，这导致了相同的ModuleNotFoundError。卸载Python并再次安装会产生相同的结果。我目前根本无法使用手动安装的Python或pip

解决方案是使用Python的第二次安装（Anaconda）来修复我损坏的Python。我的Anaconda Python维护一组单独的已安装软件包，因此它仍在工作。我打开Anaconda提示符并运行（reference）：

pip install  target="c:\users\me\appdata\local\programs\python\python38\lib\site-packages" wrapt

这将wrapt重新安装到正确的site-packages文件夹中。我原来的Python现在可以工作了
