第二十五章 Pyinstaller打包

25.1 下载Pyinstaller

25.2 了解Pyinstaller命令参数

25.3 打包示例

25.4 小结

写完的程序如果要发给别人使用，但对方并没有安装python环境，也没有安装PyQt5库时怎么办呢？最好的解决办法就是将程序打包成可执行文件，这样就算在一台没有安装python环境和PyQt5库的电脑上也可以使用，非常方便。

25.1 下载Pyinstaller

windows上下载：

pip install pyinstaller

Linux上下载：

pip3 install pyinstaller

Mac上下载：

pip3 install pyinstaller

下载完后我们打开终端，输入pyinstaller，若显示如下，则表示安装成功：

25.2 了解Pyinstaller命令参数

这里我们只需要了解几个常用命令即可，详细用法请参考Pyinstaller手册：

参数	用处
-F	将程序打包成一个文件
-w	去除黑框
-i	添加程序图标

25.3 打包示例

我们就将第五章的登录框小程序拿过来打包作为示例好了，该程序的代码如下：
