Python報錯 ImportError: DLL load failed while importing win32api: %1 不是有效的 Win32 應用程序 的解決方法

今天在用jupyter notebook 的時候發生了kernel error,點開之后提示了以下報錯信息

主要先看后兩行報錯信息,我們知道jupyter notebook再import win32api的時候報錯了

這可能是由於python版本是64位的,但電腦中已經存在了32位的pywin32所導致的

我們在命令行中運行以下代碼來卸載pywin32

pip uninstall pywin32

由於可能電腦中存在多個版本的pywin32,所以卸載完成后在運行以下代碼查看時候還有沒卸載的pywin32

pip show pywin32

如果返回了如下結果,則說明電腦中仍然存在pywin32

C:\Users\boqia>pip show pywin32
Name: pywin32
Version: 227
Summary: Python for Window Extensions
Home-page: https://github.com/mhammond/pywin32
Author: Mark Hammond (et al)
Author-email: [e-mail]
License: PSF
Location: e:\anaconda3\lib\site-packages
Requires:
Required-by: jupyter-core, xlwings, pypiwin32

這時候我們只需要在執行一次卸載命令就行了

pip uninstall pywin32

再徹底卸載完pywin32之后,我們在使用以下命令,安裝所兼容的pywin32

pip install pywin32

安裝完成后,應該就不會再報錯了.
