我第一次从github克隆了一个存储库。
我去本地机器上查看，所以在mac上的本地存储库中，我运行了以下命令
bin/rails服务器
我得到以下错误：
在任何源中都找不到activesupport-5.0.0.1
运行bundle install安装丢失的gem。
所以我按照建议运行了bundle install命令，但是它给出了以下错误
安装OJ（2.12.14）时出错，Bundler无法继续。
在绑定之前确保gem install oj -v '2.12.14'成功。
所以按照建议我运行：gem install oj-v'2.12.14'
然后我收到了一条很长的消息，上面有警告和一个错误（见下文）。有什么想法吗？

最佳答案
fixnum在ruby 2.4中不再是一个东西。要么降级你的ruby，要么更新oj到2.16.1，它支持ruby 2.4。
