我按顺序执行了以下步骤，但在运行 webrick 时遇到问题
我有一个centos 6安装
第 1 步：http: //blog.jeffcosta.com/2011/07/22/install-ruby-version-manager-rvm-on-centos-6/
第二步：server-world.info/en/note?os=CentOS_6&p=mysql
第三步：sudo install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config gem install -y mysql -- --with-mysql-config=/usr/bin/mysql_config
它安装了所有的宝石，没有任何问题。
但是当我从使用rails new simple_cms -d mysql创建的应用程序中加载 webrick

从 [https://rubygems.org/] 获取 gem 元数据。
无法加载 OpenSSL。您必须使用 OpenSSL 支持重新编译 Ruby，或将 Gemfile 中的源代码从“https”更改为“http”。rvm.io/packages/openssl 提供了使用 RVM 使用 OpenSSL 进行编译的说明。
