1. 在使用pyinstaller打包代碼成exe文件時，出現No module named 'Crypto.Math' 錯誤的原因應該是：現在名稱換了。
解決方法是：
pip uninstall crypto
pip uninstall pycryptodome
pip install pycryptodome
2. lib not found的警告，沒找到很好的解決方法，就是默默地下載了幾個warning里面的dll文件放到對應路徑下，然后就沒該dll的warning了，下載不到的dll還是會出現warning。
注意的是：沒有下載這些dll時，我打包的exe文件也沒問題，可運行。
有warning的整個運行日志如下：

也有人說：從win10改到win7上打包，就沒這些警告：https://blog.csdn.net/dodwind/article/details/83107378。
