Question

Ubuntu 14.04。

所以一切正常，我的终端打开了两个标签 - 一个标签在我的sebcoles项目上运行了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，我换成了目录。

我只是将所有内容粘贴在这里 - 它非常清楚：

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 - 我无能为力。救命啊！

Answer 1

您已安装rvm但忘记安装rails gem。安装使用：

gem install rails

Answer 2

原来我必须跑捆绑安装一切都很好。然而，对于我使用回形针宝石的pinteresting repo，我不得不跑 sudo apt-get install imagemagick 为了在开发中上传图像。

但是，Haven并没有提出任何新的东西，而是推送和部署到heroku。我认为应该没问题（触摸木头）。

Answer 3

我也有同样的错误。我忘了切换到正确的ruby版本并使用rvm更正gemset。就是这样，我能够解决这个问题。

$rvm list
$rvm use ruby version 
$rvm gemset use gemset-name

rails -v无法加载此类文件 - rails / cli（LoadError）
