rails -v 无法加载此类文件 -- rails/cli (LoadError) [英] rails -v cannot load such file -- rails/cli (LoadError)

问题描述

Ubuntu 14.04.

Ubuntu 14.04.

所以一切正常，我的终端打开了两个选项卡——一个选项卡在我的 sebcoles 项目上运行 webbrick，另一个选项卡我用来克隆我的 english_teacher 存储库.一切都下载好了，我切换到目录.

So everything was working fine and I had my terminal open with two tabs - one tab had webbrick running on my sebcoles project, and the other tab I used to clone my english_teacher repo. It all downloaded fine and I changed into the directory.

我会在这里粘贴所有内容 - 一切都非常清楚:

I'll just paste everything here - it's all pretty clear:

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，基本上我现在被搞砸了 - 我什么也做不了.帮助！

So, basically I'm screwed at the moment - I can't do anything. Help!

推荐答案

原来我只需要跑捆绑安装一切都很好.但是，对于使用回形针 gem 的 pinteresting repo，我必须运行sudo apt-get 安装 imagemagick以便上传开发中的图片.

Turns out I just had to run bundle install and everything was fine. However, for my pinteresting repo, which uses the paperclip gem, I had to run sudo apt-get install imagemagick in order to upload images in development.

虽然还不敢提交任何新内容并推送和部署到 heroku.不过我觉得应该没问题(碰木头).

Haven't dared commit anything new and push and deploy to heroku yet though. I think it should be fine though (touch wood).
