【问题描述】：

我刚刚完成了 tryruby.org 教程，然后是 rubyforzombies.org 教程，一切都很好。然后我开始使用我的 Mac Os X 10.6 终端安装 Ruby 1.9.2 和 Rails 3.0.4，到目前为止一切顺利。

我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，但是当我运行最后一行 rails server 时，我只是收到一条错误消息：

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，这个设置比现在学习语言更难。

无论如何，如果有人能帮助我解决这个设置问题，那就太好了。

到目前为止，我只使用 MAMP 在本地运行 PHP（它会自动为我设置一切），所以我习惯使用 MySQL 而不是 SQLite。

是否有理由选择其中之一？

是否有适用于 SQlite 的 GUI 工具，例如适用于 MySQL 的 PhpMyAdmin？

如何让 Rails 与 MySQL 一起工作？（我尝试将-d mysql 选项添加到rails new 命令中，但随后出现与mysql2 相同的错误，而不是sqlite3。

谢谢，詹尼斯

更新：

所以我按照下面的建议在我的ruby3sqlite 目录中运行了$ bundle install，这会在控制台中返回：

Jannis:rail3sqlite Jannis$ bundle install

Jannis:rail3sqlite Jannis$ rails server
Could not find gem 'sqlite3 (>= 0, runtime)' in any of the gem sources listed in your Gemfile.

如果您对这些行的含义以及我需要做什么有任何想法，我将非常感谢您的帮助。

感谢到目前为止的建议！非常感谢。

更新 2：

看来上述情况只是暂时的，可能是 gems 服务器已关闭或我的 ISP 有问题？谁知道……无论哪种方式，我都重新运行了bundle install 命令，现在一切正常。

谢谢。

【问题讨论】：

您可能需要从 macport 安装 sqlite3 或从 sqlite3 源代码编译。如果你有 macport 已经尝试，sudo port upgrade sqlite3 然后运行，sudo gem install sqlite3-ruby
谢谢，我安装了 Macports 但运行第二个命令我只得到返回：Error: Port sqlite3-ruby not found。我如何知道/找出我需要安装哪个版本？

标签： ruby-on-rails ruby macos rubygems installation

【解决方案1】：

在 Rails 3 中，项目所依赖的 gem 列在项目目录根目录下的 Gemfile 中。您需要运行 bundle install 以 (1) 确保您的应用程序依赖项已安装，以及 (2) 生成 Gemfile.lock 以准确确定您的应用程序应使用这些 gem 的哪些版本。（请注意，一个命令会为您完成这两件事。）

运行bundle install 后，您应该可以使用rails server 启动您的开发服务器。

您可以在the Bundler homepage 了解有关管理您的Gemfile 的系统Bundler 的更多信息。

感谢您的详细解释。我进入目录并运行$ bundle install，但返回了fetch error（我已经用完整的错误（长列表）更新了上面的内容。我尝试理解错误消息/跟踪但无法完全理解。跨度>
更新 2：似乎它可能只是暂时的失败。刚刚回到它并重新运行相同的bundle install 命令，现在我已经启动并运行了！耶。最后一件事......我怎样才能让它在自定义域（本地）而不是 localhost:3000 上运行？我可能需要一次运行超过 1 个 ror 应用程序，所以我必须找到一种方法来找到诸如 app1.local:3000 app2.local:3000 等的路径。可以这样做吗？
@Jannis 我认为这就像 Apache 虚拟主机
@mathepic，是的，我已经相对弄清楚了那部分，但是为了进行主机条目，我仍然需要一些唯一的地址来运行这些站点，......我会有做一些研究，我猜。不过谢谢！
检查rails server -h;您可以通过传递-p portnum 或--port=portnum 来传递自定义端口，例如rails server -p 8080。

【解决方案2】：

确保cd rails3sqlite3，然后bundle install。

【解决方案3】：

我在 Snow Leopard 10.6 上为 Rails 3/Ruby 1.9.2/RVM 编写了一个程序......并将其发布在一个网站上。看看吧，它可能对您的一些问题有所帮助。

如需在 Mac 上安装全新的 rails4 (ruby 2)，请查看这篇博文：

我已经在我自己的 Mac 上尝试并测试了这种方法。以为我会与社区分享。希望你会发现它有用。
