【问题描述】：

我将发行版从 Ubuntu 更改为 Elementary OS。我保留了我的/home 目录，这样我就不必安装任何东西了。

我按照 GoRail 的 guide 安装 Rails。

现在，当我尝试重新安装同一指南中的所有内容时，结果发现 RVM、Ruby 和 Rails 已经存在。

➜  sample_app git:(master) ✗ rails -v
Rails 4.2.2

但是，当我转到我的旧项目并尝试启动服务器时，它会引发以下错误：

➜  sample_app git:(master) ✗ rails s

【问题讨论】：

您在使用 RVM 吗？您是否检查了您的主目录，您是否像安装新操作系统之前一样拥有可用的 gemset？

@RameshKumarThiyagarajan 是的，我正在使用 RVM。我不知道我是 Rails 的新手。我应该怎么做才能检查宝石？

在创建 gemset 后尝试bundle install

【参考方案1】：

根据您的错误信息

There was an error while trying to load the gem 'uglifier'. (Bundler::GemRequireError)

您似乎没有安装 NodeJS。运行

sudo apt-get install nodejs
bundle install

见“There was an error while trying to load the gem 'uglifier'. (Bundler::GemRequireError)”。
