ruby-on-rails – 错误：安装oj时出错：

我去了我的本地机器,所以在我的Mac上的本地存储库中运行以下命令

bin / rails服务器

我收到以下错误：

无法在任何来源中找到activesupport-5.0.0.1
运行bundle install以安装缺少的gem.

所以我按照建议运行了bundle install命令,但后来它给了我以下错误

安装oj(2.12.14)时发生错误,Bundler无法继续.
在捆绑之前确保gem install oj -v’2.12.14’成功.

所以我按照建议运行：gem install oj -v’2.12.14′

然后我得到了一个非常长的消息,警告和错误(见下文).有什么想法吗？

ERROR:  Error installing oj:
