Question

我正在尝试在我的系统上运行Less并运行，但是我遇到了错误。

到目前为止采取的步骤

gem install less
rails plugin install git://github.com/cloudhead/more.git
# restart everything
# moved styles.css to app/stylesheets/styles.less
rake more:generate

希望运行最后一行将在。{1}}中从.less源创建styles.css。但是，我收到错误：

public/stylesheets

发生了什么事？

设定：

Generating css from less files in app/stylesheets.
rake aborted!

好看它this line更多是在调用engine = File.open(file){|f| Less::Engine.new(f) }并查看old code they do define the Less::Engine中的Less项目的源代码时导致错误但是他们已将gem移到了new version已包含对源的一些更改，但未定义Less :: Engine。

我建议您按照official less website上的说明启动并运行。似乎不再支持more插件。

未初始化的常量Less :: Engine
