有人翻译吗？

#20 楼 @Mandy [email protected] 多谢了

#12 楼 @Mandy 发一份给我吧。

电子版有中文的吗？

社区是用得这个吗？

#9 楼 @leeboqiang

哦。我以为 4 已经正是版了啊，看到 社区的管理员说他用 2 +4 了。还以为已经正是版了。

#5 楼 @saiga

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
Post-install message from rdoc:
Depending on your version of ruby, you may need to install ruby rdoc/ri data:

<= 1.8.6 : unsupported
 = 1.8.7 : gem install rdoc-data; rdoc-data --install
 = 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!
~/Ruby-project$ 

在运行 run bundle install的过程中，我开了另外一个终端。
执行了 sed -i -e 's/ftp\.ruby-lang\.org\/pub\/ruby/ruby\.taobao\.org\/mirrors\/ruby/g' ~/.rvm/config/db

那现在

$cd blog/
rails s #这一步瞎报错，百度了半天， 然后安装下面的这写包
gem install execjs
gem install ref libv8 therubyracer
sudo apt-get install nodejs

终于启动了， @saiga 多谢你啊，没有你的指点，我启动不了。

我也是新手，刚刚也装了 ubuntu 系统来学习 rails

#5 楼 @saiga

升级一下 rvm，rubygems现在是 2.0 了

自己的升级过程：
1. rvm get stable
2. rvm install ruby-2.0.0-p0
3. rvm use ruby-2.0.0-p0 --default
4. gem install rails
5. cd project & bundle install

多谢你的指点啊。但是 我这样子操作之后 Rails 还是 3.2.12 没有升级到 4 啊“

$ ruby -v
ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-linux]
$ rails -v
Rails 3.2.12
$ gem -v
2.0.0.rc.2

#23 楼 @bydmm 你的 rails 升级成功了吗？

我的 ruby 升级成功了，但是 rails 不知道如何升级。

#14 楼 @huacnlee

多谢了。
