我无法在OS X Sierra 10.12.3中链接OpenSSL。我尝试链接的命令是brew link --force openssl。
警告是：
Warning: Refusing to link: openssl
Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib
如何解决此问题？
