我正在尝试在 debian 上的 rails 上安装 ruby​​ ......我安装了所有东西。

我也安装了 execjs、therubyracer 和 node.js。

每次我想创建一个新控制器时，它都会说：

    from bin/rails:4:in `<main>'

我在安装 execjs、therubyracer 和 node.js 后重新启动...

对于有可用二进制版本的 ruby​​racer gem 的平台，除了 ruby​​ 和 ruby​​gems 之外没有其他依赖项。如果您的系统没有二进制版本，那么您需要从源代码编译它。为此，您必须在系统某处安装 v8 > 3.11.8。

尝试将以下内容添加到您的 Gemfile

gem 'therubyracer', '0.11.0beta5'
gem 'libv8', '~> 3.11.8'

现在， cd 到您的项目并捆绑安装

$ cd <project>
$ bundle install
