ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'gcc' failed with exit status 1

主要的报错信息是这个:

ld: library not found for -lssl    # 主要信息在这里,gcc找不到这个库

解决方法

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