在 Windows 上只需要执行下面的命令，即可制作独立 exe 程序。这样就会在当前目录下产生一个名为 dist 的目录。里面就有一个名为 httpclient 的目录，我们的可执行程序 httpclient.exe 就在里面。

1
pyinstaller httpclient.py --noconsole --hidden-import PySide2.QtXml

--noconsole 指定不要命令行窗口，否则我们的程序运行的时候，还会多一个黑窗口。 但是我建议大家可以先去掉这个参数，等确定运行成功后，再加上参数重新制作 exe。因为这个黑窗口可以显示出程序的报错，这样我们容易找到问题的线索。
--hidden-import PySide2.QtXml 参数是因为这个 QtXml 库是动态导入，PyInstaller 没法分析出来，需要我们告诉它，

最后，别忘了，把程序所需要的 ui 文件拷贝到打包目录中。因为 PyInstaller 只能分析出需要哪些代码文件。 而你的程序动态打开的资源文件，比如 图片、excel、ui 这些，它是不会帮你打包的。在 dist/httpclient 中添加 logo.png, 示例代码需要从 httpclient.ui 中加载界面，也需要手动拷贝到 dist/httpclient 目录中。然后，再双击运行 httpclient.exe ，完美！
