失败启动Rails Server Windows 7 x 64

Question

我开始在铁轨上做一些试验。 今天，我正在尝试启动rails服务器，但是我的Cmd抛出此异常：

我试图重新安装rails并也运行捆绑安装。 我在GemFile中添加了一行，但没有找到解决方案。 我究竟做错了什么？

Answer 1

安装execjs和therubyracer gem

将以下内容添加到Gemfile中

gem 'execjs'

gem 'therubyracer'

然后跑

bundle install

Answer 2

首先， Could not find a JavaScript runtime. See https://gi thub.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUn available) Could not find a JavaScript runtime. See https://gi thub.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUn available)
其次，甚至不要尝试使用Windows进行Rails开发，保护您的健康
