RHEL 6 上的 Rail 服务器崩溃

Question

我是第一次使用 Ruby on Rails，尝试在 RHEL 6 上设置它。因为包管理器使用的是非常旧的 Ruby 版本。我使用 Ruby 1.9.3 从源代码进行编译，并使用

$gem install rails

Created a new app

$rails new /path/to/newapp

使用安装了 Rails，但现在当我尝试运行

$rails server

它时，它会因给定的日志而崩溃，

    => Booting WEBrick
=> Rails 3.2.1 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

我尝试搜索此错误，但没有找到有效的解决方案。

除此之外，我想向我介绍一些有用的资源，它们解释了 Ruby on Rails 的最佳实践。

Answer 1

我解决了这个问题。

我进入了 Ruby 的提取源目录，然后运行它们。

$cd /ext/openssl/
$ruby extconf.rb
$make
$make install

我希望其他人能从中得到一些帮助。 :-)

Answer 2

您的 ruby​​ 编译时不支持 SSL。尝试使用 rvm：

• https://rvm.io
• https://rvm.io/packages/openssl/
