Twitter bootstrap &引用#网格>。“核心未定义”；当LESC编译引导程序时

当我运行

lessc bootstrap.less

LESSC1.3.0（更少的编译器）[Ruby]2.2.2

---

引导程序源文件是从github克隆的。

我们需要少升级到1.3.3版

示例（如果您正在node.js中运行less）

我找到了解决办法

转到并下载repo作为zip文件

转到并下载repo作为zip文件

将/Users/ftiasch/.rvm/gems/ruby-1.9.3-p374/gems/less-2.2.2/lib/less/loader.rb替换为步骤2中repo中该文件的版本（lib/less/loader.rb）

将/Users/ftiasch/.rvm/gems/ruby-1.9.3-p374/gems/less-2.2.2/lib/less/js/的内容替换为步骤1中的回购内容

那就够了！有两点需要注意：

当我实现这个解决方案时，我使用的是ruby 1.9.3-p385

将/Users/ftiasch/.rvm/gems/ruby-1.9.3-p374/gems/less-2.2.2/的内容替换为步骤2中的repo内容对我不起作用。如果它真的

这里也有同样的问题。lessc 1.3.0，github source 2.3.0的引导程序也有同样的问题，但我正在使用节点运行

lessc

：

1.3.0（更少的编译器）[JavaScript]

从github source使用
lessc 1.3.0
编译的github source引导程序2.3.0

对我来说也失败了，但在升级到

lessc 1.3.3.3

后工作。（注意，我的@Import语句出现了问题——我必须使用一个Windows框将/to\）LESC的ruby包装器似乎有点过时。因此，最好使用较少的.js。

lessc -v

sudo npm install -g less
