openssl/aes.h' 文件

Question

我正在尝试安装我在here找到的代理重新加密方案的Python实现。

运行时

$ sudo python setup.py install

我收到错误

fatal error: 'openssl/aes.h' file not found

有一些类似的问题（this或this（不适用于Mac）），但那里的答案都没有解决我的问题。

我已经尝试过（全部取自我找到的答案）：

1. 运行

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

   并重试；

2. brew install openssl

   ，然后再试一次；

3. brew reinstall python

   ，然后再试一次；

选项1.退回

有什么想法吗？

Answer 1

首先检查

$(brew --prefix openssl)/include

所指的路径是否存在。

如果以上没问题，你可以尝试一下

$ cd /usr/local/include
$ ln -s ../opt/openssl/include/openssl .

Answer 2

指定环境变量解决了我的问题：

For MacOS users:

Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries. This means that you will need to export some OpenSSL settings yourself.

Use the following commands:

export CFLAGS="-I$(brew --prefix openssl)/include"
export LDFLAGS="-L$(brew --prefix openssl)/lib"
