由于 wrapt 的 ModuleNotFoundError，我在安装包时遇到困难，所以我删除并尝试重新安装 wrapt.

I was having difficulty installing a package because of a ModuleNotFoundError for wrapt and so I removed and tried to reinstall wrapt.

我运行了一次卸载程序，然后从一个位置删除了 wrapt.我尝试安装，但要求已经满足，所以我再次卸载了wrapt.看下面三个命令:

I ran the uninstall once, and wrapt was removed from one location. I tried to install, but the requirement was already satisfied, so I uninstalled wrapt again. See the three commands below:

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.

I thought I was all ready to start with a clean slate, but no such luck. Now I receive the following error whenever I try to run python or pip.

Fatal Python error: init_import_size: Failed to import the site module
Python runtime state: initialized
Traceback (most recent call last):
  File "c:\users\me\appdata\local\programs\python\python38\lib\site.py", line 580, in <module>
    main()
  File "c:\users\me\appdata\local\programs\python\python38\lib\site.py", line 575, in main
    execusercustomize()

  File "c:\users\me\appdata\local\programs\python\python38\lib\site-packages\certifi_win32\bootstrap.py", line 25, in _register_bootstrap_functions
    from . import wrapt_certifi
  File "c:\users\me\appdata\local\programs\python\python38\lib\site-packages\certifi_win32\wrapt_certifi.py", line 3, in <module>
    import wrapt
ModuleNotFoundError: No module named 'wrapt'

我尝试过为不使用 pip 的 wrapt 寻找安装，但我没有成功.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 并再次安装产生了相同的结果.我目前根本无法使用手动安装的 Python 或 pip.

I've tried finding installation for wrapt that does not use pip, but I haven't been successful. I also attempted upgrading Python from 3.8.1 to 3.8.3, which resulted in the same ModuleNotFoundError. Uninstalling Python and installing again yielded the same result. I currently cannot use my manually installed Python or pip at all.

你会推荐什么?

推荐答案

解决方案是使用 Python (Anaconda) 的第二个安装来修复我损坏的 Python.我的 Anaconda Python 维护着一组单独的安装包，所以它仍然可以工作.我打开了一个 Anaconda 提示并运行(参考):

The solution was to use a second installation of Python (Anaconda) to fix my broken Python. My Anaconda Python maintains a separate set of installed packages, so it was still working. I opened an Anaconda prompt and ran (reference):

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

这在正确的 site-packages 文件夹中重新安装了 wrapt.我原来的 Python 现在可以工作了.

This reinstalled wrapt in the correct site-packages folder. My original Python is now working.
