pip 安装M2Crypto时报错,错误信息如下,找不到openssl相关文件

ubuntu18下解决方法:

sudo apt install swig libssl-dev
pip install M2Crypto

mac 下解决方法

brew install openssl
brew install swig
env LDFLAGS="-L$(brew --prefix openssl)/lib"  CFLAGS="-I$(brew --prefix openssl)/include"  SWIG_FEATURES="-cpperraswarn -includeall -I$(brew --prefix openssl)/include"
pip install M2Crypto

注意:linux和mac支持的M2Crypto最新版本不一样
