1. 在使用pyinstaller打包代码成exe文件时，出现No module named 'Crypto.Math' 错误的原因应该是：现在名称换了。
解决方法是：
pip uninstall crypto
pip uninstall pycryptodome
pip install pycryptodome
2. lib not found的警告，没找到很好的解决方法，就是默默地下载了几个warning里面的dll文件放到对应路径下，然后就没该dll的warning了，下载不到的dll还是会出现warning。
注意的是：没有下载这些dll时，我打包的exe文件也没问题，可运行。
有warning的整个运行日志如下：

也有人说：从win10改到win7上打包，就没这些警告：https://blog.csdn.net/dodwind/article/details/83107378。
