python做exe需要注意32位和64位的问题

1、最开始的方法用的是下载py2exe，但在cmd 里执行的时候，一直提示 “初始化失败”，遂放弃。

后来知道 为什么不使用py2exe？

因为 py2exe打包完后只能在相同系统下运行；打包同时需要打包dll文件等各种文件

pyInstall打包完以后只有一个exe运行文件

2、所以用pyInstaller的方法

在pip 中直接安装就好了

3、还要安装pywin32，安装这个时遇到了问题

pywin32下载地址 
[https://sourceforge.net/projects/pywin32/files/pywin32/Build%20221/] 

按理说下载的.exe文件直接安装，其默认下一步，他会自己找到python的本地目录，但出现了一个问题

Python version 2.7 required， which was not found in the registry.

解决

桌面创建文件：register.py

# 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()

保存之后在cmd中进入桌面目录，执行python registed.py 
即可重新运行pywin32的安装 
（补充，pywin32必须安装成对应的版本，python是32位的，电脑是64位的，安装的pywin32必须是32位才行）
