RHEL 6 上的 Rail 服务器崩溃

Question

我是第一次使用 Ruby on Rails，试图在 RHEL 6 上进行设置。因为包管理器的 Ruby 版本非常旧。我使用 Ruby 1.9.3 从源代码编译并使用

安装 rails

$gem install rails

使用

创建了一个新应用

$rails new /path/to/newapp

但现在当我尝试运行时

$rails server

它会因给定日志而崩溃

=> Call with -d to detach
=> Ctrl-C to shutdown server

我已尝试搜索此错误，但未找到有效的解决方案。

除此之外，我想指出一些有用的资源，它解释了 Ruby on Rails 的最佳实践。

Answer 1

我解决了这个问题。

我进入 Ruby 的提取源目录，然后运行这些。

$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/
