错误：root：未找到哈希 md5 的代码

Question

我在一台没有 root 访问权限的 Linux 机器上。我构建了自己的 openssl 和 python (2.7.13) 本地副本。当我尝试在 python 中导入 hashlib 时，我收到以下错误消息：

更新：我刚刚意识到 python 构建未能构建 hashlib 模块：

我应该如何解决这个问题？看起来问题可能在于它正在 /usr/include/openssl 中寻找 openssl 标头，但我正在尝试使用我自己安装的 openssl。

Answer 1

弄清楚了。python 构建脚本正在查找/usr/includeopenssl 头文件。由于我安装了自己的本地版本的 openssl，因此这些头文件是错误的。

因此，我设置CFLAGS并-i/location/correct/openssl/header/files进行了make distclean配置、构建并且它起作用了。
