我试过
sudo pip安装加密
错误消息是

然后我搜索了一些帖子并尝试了
brew安装pkg配置libffi openssl
警告：pkg-config-0.28已安装警告：libffi-3.0.13已安装警告：openssl-1.0.2d_1已安装
和
CFLAGS="-I/usr/local/opt/openssl/include"sudo pip安装加密==0.8
我收到这个错误消息：

我也试过
brew安装pkg配置libffi openssl
env LDFLAGS="-L$(brew--前缀openssl)/lib"CFLAGS="-I$(brew---前缀openssl)/include"pip安装加密
得到了这个

请帮我解决这个问题。非常感谢。
对我有效的是：
sudo brew reinstall python
我通过以下命令得到了这个修复：
brew reinstall python
ARCHFLAGS="-arch x86_64" LDFLAGS="-L/usr/local/opt/openssl/lib"
CFLAGS="-I/usr/local/opt/openssl/include" pip install cryptography
brew link —force openssl
在Mac OS El Capitan上安装加密软件包。如加密安装文档中所述
env LDFLAGS="-L$(brew--前缀openssl)/lib"CFLAGS="-I$(brew---前缀openssl)/include"pip安装加密
