Answer 1

升级到莫哈韦沙漠后，我遇到了与您相同的错误。经过一番挖掘之后，以下步骤会有所帮助：

brew info openssl

输出很有用。如果您使用的是 bash 或 zsh ，则消息为：

要让编译器找到openssl，您可能需要设置：

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

执行上述命令后，一切恢复正常。

此外，如果您使用的是鱼。消息是：

要让编译器找到openssl，您可能需要设置：

set -gx LDFLAGS "-L/usr/local/opt/openssl/lib"
set -gx CPPFLAGS "-I/usr/local/opt/openssl/include"

Answer 2

export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/

来自ld: library not found for -lssl after Mac OS Sierra upgrade

对我有用。
