Python3.6安装pyinstaller

很久之前装了python可是最近需要把xxx.py打包成xxx.exe，然后找了教程试了也无果，各种失败

首先在cmd下输入：python -m pip install PyWin32

然后在官网下载pyinstaller，下载前先看自己的python是32bit还是64bit：

python

在官网下载对应版本，解压，重命名（根据个人爱好）然后移动到python目录下：

打开cmd，进入刚刚复制的文件夹的目录，执行：python setup.py install

然后进入pyinstaller-pyinstaller文件夹下的script文件夹：

复制这个路径到环境变量

如果过程中出现未注册的提示信息复制以下代码运行后在安装

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()
