rails -v无法加载这样的文件 - rails/cli(LoadError)

Question

Ubuntu 14.04.

所以一切都运行良好,我的终端打开了两个标签 - 一个标签在我的sebcoles项目上运行webbrick,另一个标签我用来克隆我的english_teacher repo.这一切都下载得很好,我改成了目录.

我会在这里粘贴所有内容 - 这一切都很清楚:

andrew:projects$ cd pinteresting
RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore /home/andrew/projects/pinteresting/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

ruby-2.1.5 is not installed.
To install do: 'rvm install ruby-2.1.5'

andrew:pinteresting$ rvm install ruby-2.1.5

Warning, new version of rvm available '1.26.11', you are using older version '1.26.10'.
You can disable this warning with:    echo rvm_autoupdate_flag=0 >> ~/.rvmrc
You can enable  auto-update  with:    echo rvm_autoupdate_flag=2 >> ~/.rvmrc

所以,基本上我现在搞砸了 - 我做不了什么.救命!

Answer 1

你已经安装rvm但忘了安装railsgem.安装使用:

gem install rails

Answer 2

结果我只需要运行捆绑安装，一切都很好。但是，对于使用回形针 gem 的 pinteresting 存储库，我必须运行 sudo apt-get install imagemagick 才能上传开发中的图像。

不过，还不敢提交任何新内容并推送和部署到 Heroku。我认为应该没问题（触摸木头）。
