正如标题所说，我在虚拟机上克隆了我的一个项目，但我似乎无法使用“rails s”启动 RoR Web 服务器。起初我以为我有一个很有趣的 gem，所以我在 Gemfile 中将它屏蔽了。但是，当我这样做时，另一个宝石不起作用。我目前不知道该怎么做，所以我希望有人可以帮助我。感谢您的阅读，祝您有美好的一天！

您没有安装 Javascript 运行时。

如果您使用的是 Ubuntu 或其衍生版本，则可以通过运行来安装 NodeJS 运行时。

sudo apt-get install nodejs

如果您使用的是 Debain

sudo aptitude install nodejs

要使用 yum 在系统上安装 nodejs，请在终端中键入以下内容：

yum -y install nodejs

根据发布的描述，它表明我无法安装 gem 'uglifier'。

Uglifier 是一个 JS 包装器，它需要一个 JS 运行时运行或 JS 解释器。

Nodejs 不是必需的，但 JS 运行时或解释器是必需的。

这就是 NodeJS 在这里的作用。

如果不是 NodeJS，您将需要另一个 JS 运行时/解释器。

您应该运行以下命令在 Ubuntu 中安装 NodeJS

sudo apt-get install nodejs

或为 OSX 运行它

brew install nodejs
