python报错 ModuleNotFoundError: No module named 'win32api' //import win32api ImportError: DLL load fai

大概的错误就是：
import win32api
ImportError: DLL load failed: 找不到指定的程序。

具体点：

解决方法：

安装 win32api 下面带有连接，直接安装后运行即可（注意你的python版本，如果不对的话就退一个版本安装，比如你安装的3.8的python，但是 安装下面连接的win32api后没有反应 ，就哟啊退回一个版本 比如3.7，安装3.7的win32api)

安装好后运行：

下一步

下一步，然后安装即可

如果版本不对，可能就会有如下上情况 ， 直接换一个版本就好了。
