错误：安装oj时出错：

Question

我刚刚首次从GitHub克隆了一个存储库。

我去看看我的本地机器上，所以我的Mac上的本地仓库内我跑以下命令

斌/导轨服务器

我得到了以下错误：

无法在任何来源中找到activesupport-5.0.0.1 运行bundle install以安装缺失的宝石。

所以我然后跑捆绑安装命令的建议，但随后它给了我下面的错误

在安装OJ（14年2月12日）发生了错误，并且捆扎机无法继续。 确保gem install oj -v '2.12.14'在捆绑之前成功。

所以的建议，我跑：创业板安装OJ -v“14年2月12日”

然后我得到的警告很长的信息及错误（见下文）。有什么想法吗？

Answer 1

Fixnum不再是红宝石2.4的东西。降级你的红宝石或更新oj到2.16.1，它支持ruby 2.4。
