我刚开始尝试学习编码，并且试图让Ruby第一次运行。我已经搜索了一个多小时，找不到解决方案。当我尝试连接到服务器时，出现此错误：

然后，当我尝试安装
execjs然后安装execjs --source http://rubygems.org时，会发生以下情况：C：\ Sites \ railsbridge \ test_app> gem安装execjs错误：无法
找到一个有效的gem'execjs'（> = 0），这是为什么：
无法从https://rubygems.org/下载数据-SSL_connect返回= 1 errno = 0状态= SSLv3读取服务器证书B：
证书验证失败（https：//
api.rubygems.org/latest_specs.4.8.gz）
C：\ Sites \ railsbridge \ test_app> gem install execjs-源http：//
rubygems.org成功安装execjs-2.2.2解析
execjs-2.2.2的文档完成安装的文档
0秒后execjs警告：无法从'https：//提取数据

（https://api.rubygems.org/latest_specs.4.8.gz）已安装1个宝石
我不知道我在做什么错。我也在Windows 7上运行。
更新：execjs安装成功。但是当我安装therubyracer时，我得到了：
C：\ Sites \ railsbridge \ test_app> gem安装therubyracer
暂时增强PATH以包括DevKit ...
构建本机扩展。这可能需要一段时间...
错误：安装therubyracer时出错：

ps：对我的格式感到抱歉，我正在尝试学习如何正确使用它
最佳答案
尝试将其添加到gem文件中
gem 'execjs'
gem 'therubyracer', :platforms => :ruby
