Question

我是Ruby on Rails的新手。所以，我之前遇到过这个错误，我重新安装了rails和ruby并再次安装它们，但我仍然得到它。错误是：

我尝试更新uglifier gem，但什么也没发生。

Answer 1

看起来你没有安装nodejs

sudo apt-get install nodejs

应该工作!!!

Answer 2

问题是我没有安装nodejs。安装完成后，一切顺利。

Answer 3

你是什么gemfile / gem list？

实际安装meteor并不算作安装了nodejs。 uglifier包需要nodejs，这很简单：yum install nodejs解决了这个问题。

无法启动rails服务器，我收到错误
