error: command ‘D:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30037\bin\HostX86\x64\cl.exe’ failed with exit code 2
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for pycrypto

解决方法：
将Microsoft Visual Studio安装目录（D:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30037\include）下的stdint.h文件复制到
D:\Windows Kits\10\Include\10.0.19041.0\ucrt
并将D:\Windows Kits\10\Include\10.0.19041.0\ucrt目录下的inttypes.h下的尖括号改成双引号（引号是引用非标准库的头文件,编译器从用户的工作目录开始搜索）
然后重新安装：pip install pycrypto
