pycrypto安装报错error：Unable to find vcvarsall.bat

# Unable to find vcvarsall.bat 由于Win10系统安装`pip install pycrypto`报C++错误 从 https://www.lfd.uci.edu/~gohlke/pythonlibs/ 搜索`pycrypto`，但没有找到想要的`whl`文件，进入了 https://www.dlitz.net/software/pycrypto/ ，然后下载了 pycrypto-2.6.1.tar.gz ```bash p\pycrypto-2.6.1>python setup.py install running install running build running build_py running build_ext warning: GMP or MPIR library not found; Not building Crypto.PublicKey._fastmath. building 'Crypto.Random.OSRNG.winrandom' extension error: Unable to find vcvarsall.bat ``` 手动安装仍然报错。 ~~按照网上的办法进行安装~~ `pip install pycryptodome` ~~依旧不行。~~ # 解决办法 参考 https://blogs.msdn.microsoft.com/pythonengineering/2016/04/11/unable-to-find-vcvarsall-bat/ 下载 [Visual C++ Build Tools 2015](http://go.microsoft.com/fwlink/?LinkId=691126) ##
