在Mac上找不到openssl/aes.h'文件

Question

我試圖安裝一個代理重新加密方案的python實現，我發現here。

當運行$ sudo python setup.py install我回來了錯誤

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

有這樣的周圍（this或this（不適用於Mac）），但沒有一個答案有固定我的問題了幾個問題。

我試過（全部來自答案取我發現）：

1. 運行env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install cryptography並再次嘗試;
2. brew install openssl並再次嘗試;
3. brew reinstall python並再次嘗試;

選項1.返回

Answer 1

首先檢查是否存在brew --prefix openssl)/include指出的路徑。

如果上面是好的，你可以嘗試

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