Ruby on rails RubyonRails:MacOSX10.6安装失败。请帮忙,ruby-on-rails,ruby,macos,rubygems,installation,Ruby On Rails,Ruby,Macos,Rubygems,Installation,我刚刚完成了tryruby.org教程，接着是rubyforzombies.org教程，一切都很好。 然后我开始使用MacOSX10.6终端安装Ruby1.9.2和Rails3.0.4，到目前为止还不错 我已经通过命令行创建了一个rails应用程序，如下所示： $ rails new ~/Sites/_ruby/rail3sqlite $ cd rails3sqlite $ rails server 文件夹和文件结构正在成功生成，但当我运行最后一行rails server时，我只收到一个错

我刚刚完成了tryruby.org教程，接着是rubyforzombies.org教程，一切都很好。 然后我开始使用MacOSX10.6终端安装Ruby1.9.2和Rails3.0.4，到目前为止还不错

我已经通过命令行创建了一个rails应用程序，如下所示：

$ rails new ~/Sites/_ruby/rail3sqlite

$ cd rails3sqlite

$ rails server
文件夹和文件结构正在成功生成，但当我运行最后一行
rails server
时，我只收到一个错误，提示：

Could not find gem 'sqlite3 (>= 0, runtime)' in any of the gem sources 
listed in your Gemfile.
我怎样才能让它工作

在我看来，在这一点上，这种设置比学习语言更难

不管怎样，如果有人能帮我解决这个设置问题，那就太棒了

到目前为止，我只使用MAMP在本地运行PHP（这会自动为我设置所有内容），所以我习惯于使用MySQL而不是SQLite

有理由选择其中一个而不是另一个吗

是否有针对SQlite的GUI工具，例如针对MySQL的PhpMyAdmin

如何让rails使用MySQL？（我尝试将
-d mysql
选项添加到rails新命令中，但与
sqlite3
相反，
mysql2
出现了与上述相同的错误

谢谢， 詹尼斯

更新：

因此，我遵循下面的建议，在我的
ruby3sqlite
目录中运行
$bundle install
，并在控制台中返回：

然后是所有这些行：
