如何在Mac OS X中为python3安装加密? [英] How to install cryptography for python3 in Mac OS X?

问题描述

执行pip3 install cryptography时，pip3给出错误:

严重错误:找不到'openssl/aes.h'文件
#include <openssl/aes.h>

fatal error: 'openssl/aes.h' file not found
#include <openssl/aes.h>

1个错误.
错误:命令'/usr/bin/clang'失败，退出状态为

1 error generated.
error: command '/usr/bin/clang' failed with exit status 1

我与brew info openssl进行了核对，并得到了答案:

I checked with brew info openssl and got the answer:

通常，这对您没有任何影响.如果你建立你的 自己的软件，它需要此公式，您需要将其添加到 构建变量:

Generally there are no consequences of this for you. If you build your own software and it requires this formula, you'll need to add to your build variables:

LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include

LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include

现在的问题是:当我使用clang编译cpp文件时，如何告诉pip将路径添加到相应的构建变量中?

The problem now is: how can I tell pip add the paths into corresponding build variables when it uses clang to compile cpp file?

推荐答案

尝试安装scrapy我需要在Mac OS El Capitan上安装加密软件包.如密码学安装文档中所述

Trying to install the scrapy I need to install cryptography package on Mac OS El Capitan. As explained in Cryptography installation doc

env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install cryptography
