在 Mac 上找不到 openssl/aes.h' 文件

Question

我正在尝试安装我找到的代理重新加密方案的 python 实现here。

在运行$ sudo python setup.py install 时，我返回一个错误

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

周围有一些这样的问题（this 或 this（不适用于 mac）），但没有一个答案能解决我的问题。

我试过了（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 再试一次；
3. brew reinstall python 再试一次；

选项 1. 返回

我正在运行 OSX 10.12.6。

有什么想法吗？

Answer 1

首先检查$(brew --prefix openssl)/include指向的路径是否存在。

如果上面没问题，你可以试试

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

遇到了cryptography==1.0.1 的这个问题。升级到2.9.2。
