scrapy->pywin32

scrapy遇见三个问题：(仅供自己学习记录)

1：no module named win32API

https://sourceforge.net/projects/pywin32/files/pywin32/Build%20220/ 下载相对应版本安装即可。

2：安装python的pywin32时提示找不到py3.6-32

原因是找不到python的注册表，运行下面代码，安装python的注册表

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()

运行之后，在cmd输入regedit，找到python，修改36目录为36-32即可。

3：安装成功之后，cmd可以运行，pycharm的terminal不行

cmd是cmd的，pycharm是pycharm的，所以要在pycharm再安装一次。方法就是打开settings中自己定义project点击+号搜索pywin32安装即可。
