1.先下载pywin32对于的版本

下载地址：python for windows extensions

2.选择自己对应的版本，我的是python3.5版本

注意注意注意：此处一定要看清楚自己的python是什么版本

cmd中输入python查看

C:\Users\Administrator\Desktop>python
Python 3.5.2 |Continuum Analytics, Inc.| (default, Jul 5 2016, 11:41:13) [MSC v
.1900 64 bit (AMD64)] on win32

我这是64 bit的python  所以要下载64bit的pywin32

3.进入界面后，会自动倒数5秒  然后开始下载

4.安装pywin32-----双击pywin32的exe文件，若提示报错说：没有注册 ，如下图

此时，新建一个register.py 文件，把以下代码贴进去。

# script to register Python 2.0 or later for use with win32all
# and other extensions that require Python registry settings

import sys

from winreg import *

# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix

regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
    installpath, installpath, installpath
)

def RegisterPy():
    try:
        reg = OpenKey(HKEY_CURRENT_USER, regpath)
    except EnvironmentError as e:
        try:
            reg = CreateKey(HKEY_CURRENT_USER, regpath)
            SetValue(reg, installkey, REG_SZ, installpath)
            SetValue(reg, pythonkey, REG_SZ, pythonpath)
            CloseKey(reg)
        except:
            print ("*** Unable to register!")
            return
        print ("--- Python", version, "is now registered!")
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print ("=== Python", version, "is already registered!")
        return
    CloseKey(reg)
    print ("*** Unable to register!")
    print ("*** You probably have another Python installation!")

if __name__ == "__main__":
    RegisterPy()

保存之后进入cmd，切换到存储该py文件的目录，执行python registed.py即可重新运行exe文件进行pywin32的安装。

在此步骤的时候吗，若出现在pycharm中 import win32api 时报错说找不到该模块，然后我又在cmd中 import win32api 后又报错   那么请回看第二步，查看是不是pywin32 的位数版本下载错误了，错了请重新安装pywin32

同时配置环境变量
https://jingyan.baidu.com/article/915fc414c88be051394b2093.html

配置环境变量：

检查安装结果,在python命令行输入import win32api，

如果没有报错说明安装完成

如果报错说明PYTHONPATH环境变量没有配置
