PyCharm No module named 'Crypto'

Python3安裝加密庫遇到了找不到Crypto（PyCharm自動引用會有問題，一定要人工安裝）

問題描述

• Python 使用時候提示：

    import Crypto
ModuleNotFoundError: No module named 'Crypto'

Process finished with exit code 1

• 編譯報錯：

解決方案：

1. 設置環境變量

C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\INCLUDE\stdint.h

set CL=/FI"%VCINSTALLDIR%\Tools\MSVC\14.16.27023\INCLUDE\stdint.h" 然後再進行編譯。

2.安裝好以後，可能還是提示不存在：

從安裝日誌看： 有文章提到改大小寫問題就是這個原因，之前安裝過這個小寫開頭的

3.後續

最後我發現安裝好以後，代碼還是有問題。最後發現使用加密庫需要安裝pycryptodome纔對。

PS:(安裝前如已經安裝crypto,pycrypto需要卸載了，Crypto目錄如果存在也刪除掉 )

pip install pycryptodome -i https://pypi.tuna.tsinghua.edu.cn/simple
