I'm very new to Rails, so please forgive my lack of understanding. I've installed the latest versions of RubyGems, Ruby, Rails, Rake, and MySQL etc via RubyGems, but I have this problem when starting to make a basic Rails app:
我对Rails很陌生，所以请原谅我的不理解。我已经通过RubyGems安装了RubyGems、Ruby、Rails、Rake、MySQL等最新版本，但在开始制作一个基本的Rails应用时，我遇到了这个问题:

I have no idea what I did wrong, and I'm so new to this that I don't know that I could debug it if I spent my whole life working on it -- any ideas / guidance?
我不知道我做错了什么，我对这个问题太陌生了，我不知道如果我花了一辈子的时间来研究它，我能不能调试它——有什么想法和指导吗?
All help is appreciated and thanks in advance!
感谢您的帮助，谢谢!

I would recommend starting with Rails 2.3.8 if this is your first experience. There are many tutorials and wider support; 3.0 is fairly fresh with several major changes. You'll be able to upgrade from 2.3.8 to 3.0.0 eventually anyway.
如果这是您的第一次体验，我建议您从Rails 2.3.8开始。有许多教程和更广泛的支持;3.0有几个主要的变化，非常新颖。最终，您将能够从2.3.8升级到3.0.0。

I had the same error:
我犯了同样的错误:
rake aborted!
uninitialized constant Bundler
It turns out it was happening because the environment running the cron task is not set up like your env is inside a shell. The .profile and .bash_profile are not run before cron tasks. I fixed this by setting the PATH variable in crontab to what it is for the deploy user:
这是因为运行cron任务的环境并没有像您的env在shell中那样设置。.profile和.bash_profile不会在cron任务之前运行。我将crontab中的PATH变量设置为部署用户的路径:
PATH=/opt/nginx/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/Applications/sshfs/bin
You can check if this is what's causing your issue by running

从shell内部和cron任务内部。如果您得到不同的结果，它会告诉您cron任务不是运行与您在shell中所做的相同的ruby，而且cron任务运行的ruby没有安装Bundler gem。
