mac, ruby2.7.1 执行 bundle install 以后为什么会报下面这些问题？ Installing msgpack 1.5.2 with native extensions Installing puma 3.12.6 with native extensions Gem::Ext::BuildError: ERROR: Failed to build gem native extension

试试安装 openssl

brew install openssl 

bundle config build.puma --with-opt-dir=/usr/local/opt/openssl

bundle instal

Never go there. You may incur loss.
