安装github-markdown 0.6.9 gem，会引发以下错误：

2023年更新：下面的gem仍然可以工作，但我建议使用redcarpet gem来替代长期被遗弃的github-markdown gem。我们刚刚在生产环境中用redcarpet替换了github-markdown，并且只花了很少的努力。
我成功地安装了github-markdown gem，并带有以下标志：

gem install github-markdown -v '0.6.9' --source 'https://rubygems.org/' -- --with-cflags="-Wno-error=implicit-function-declaration"
