Question

贯穿杰夫摩根：黄瓜和奶酪，一切正常，直到我到达CH6数据库。去了cheezyworld，下载并解压缩app。

8300:~/cheezy2/puppies$ bundle install
Fetching gem metadata from http://rubygems.org/...........
Fetching version metadata from http://rubygems.org/...
Fetching dependency metadata from http://rubygems.org/..
Could not find addressable-2.3.1 in any of the sources

我搜索并通过另一个版本的可解决的2.3.1错误，但这导致了更多的问题。我的下一步是转到github获取最新的小狗应用程序github cheezy小狗，我已经尝试了下载zip和克隆。

我的环境:(注意，我刚刚开始使用Ruby等人）

Ubuntu 14.04
Rubymine IDE，这是一个命令行问题
/home/userid/.rvm/gems显示ruby-1.9.3.p194，ruby-2.0.0-p643，ruby-2.1.2和ruby-2.2.2

问题：

我应该使用github最新版本还是cheezyworld 版本
我应该采取什么行动让小狗应用程序在本地运行并解决错误：找不到表小狗
如何处理所有rvm错误和/或警告？

谢谢 - 详情如下

拉开dir并打开它后，我得到了：

8300:~/cheezy$ cd puppies
You are using '.rvmrc', it requires trusting, it is slower and it is not 
compatible with other ruby managers,
you can switch to '.ruby-version' using 'rvm rvmrc to ruby-version'
or ignore this warning with 
'rvm rvmrc warning ignore /home/user/cheezy/puppies/.rvmrc',
'.rvmrc' will continue to be the default project 
file in RVM 1 and RVM 2,
to ignore the warning for all files run 'rvm rvmrc warning 
ignore all.rvmrcs'.

我搜索并发现我应该这样做：

8300:~/cheezy/puppies$ rvm rvmrc warning ignore all.rvmrcs
8300:~/cheezy/puppies$ bundle install

然后我做了rails s

8300:~/cheezy/puppies$ rails s
=> Booting WEBrick
=> Rails 3.2.11 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach

根据这本书，以上是正确的。但是，当我转到网址时本地主机：3000

我在控制台看到错误：

在浏览器中我收到错误页面

ActiveRecord::StatementInvalid in Agency#index

我跑了rvm list：

:~/.rvm/gems$ rvm list
Warning! PATH is not properly set up, '/home/userid/.rvm/gems/ruby-2.2.2/bin' is not at first place,
     usually this is caused by shell initialization files - check them for 'PATH=...' entries,
     it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
     to fix temporarily in this shell session run: 'rvm use ruby-2.2.2'.

如果您正在关注黄瓜和奶酪书：

转到github puppies并克隆项目
当你cd到小狗目录时，你可能会看到关于“信任”的警告，运行命令：rvm rvmrc trust~ / your-path / puppies /
你可能想要运行：rvm list＃to ck ruby version for project
您可以运行：cat .rvmrc＃以查看项目所需的版本
确保.rvmrc中的ruby版本与rvm list中的“当前”版本匹配
阅读整个自述文件，了解最新的说明，例如： rake db：seed，rake db：migrate，在运行之前按照这些操作：rails s

黄瓜和奶酪无法在当地运行小狗app
