项目是用python, pyqt写的，今后需要打包成exe文件，今天尝试了一下，错误百出，查了很多资料，试了好几种方法都不成功。仿佛又回到了被动态链接库折磨的阴影中。。

打包使用的命令：
pyinstaller --path C:\Users\hp\AppData\Roaming\Python\Python38\site-packages\PyQt5\Qt\bin;C:\Users\hp\Anaconda3\Lib;C:\Users\hp\Anaconda3\Lib\site-packages --hidden-import PyQt5.sip -c -D main.py
我很确定，那些dll就在pyqt5/qt/bin的目录下！ 我已经加入搜索的path了，就是找不到！
我尝试过的方法：
1. 把dll加入dist中
2. 用pip重装pyqt5, 更换pyinstaller到最新版（又换回来了）
3. 把Anaconda3的Lib\bin加入到环境变量

可能跟虚拟环境有关，缺少某些dll。
1、检查一下是否缺少Python3.dll。
2、用DLL 依赖检查工具 Dependency Walker检查一下。
3、用原生Python环境试试。
