其实很简单，首先安装pyinstaller包：

# 打开cmdpip install pyinstaller

安装后，通过cmd

pyinstaller -F  D:\xxx\xx.py

还有别的参数，具体移步，这边仅简单演示一下

打包成功，会显示.exe文件的位置，找到便可直接运行

其中，-F 表示打包成单独的 .exe 文件，这时生成的 .exe 文件会比较大，而且运行速度回较慢。仅仅一个 helloworld 程序，生成的文件就 5MB 大。

另外，使用 -i 还可以指定可执行文件的图标；

PyInstaller 会对脚本进行解析，并做出如下动作：

1、在脚本目录生成 helloworld.spec 文件；

后又看到了另一种方法：
