我安装了node.js为什么我仍然收到错误？

ExecJS::RuntimeError in Users#index (RoR)

我正在尝试安装Rails。事实上我非常确定一切都已安装。我尝试了没有node.js，但我用来安装的教程推荐我只是下载节点js。我仍然遇到上面链接中提到的错误。在本教程的评论部分中提出了建议。

这里有一些东西。

您的错误No route matches [GET] "/users"与您的javascript运行时没有任何关系。相反，您缺少用户索引的路由。在您的教程中，找到将用户路由添加到config/routes.rb文件的位置。它可能看起来像resources :users ...
