我找到了this issue。但我已将我的Lessc升级到1.3。

这是版本：

lessc -v

lessc 1.3.0（LESS Compiler）[Ruby] 2.2.2

从github克隆引导源文件。

Answer 1

我们需要升级到版本1.3.3 。

示例（如果您在node.js中运行 less ）

sudo npm install -g less

Answer 2

我找到了解决方案！

转到the less.js repo并以zip文件的形式下载回购
转到this branch of the less.rb repo并以zip文件的形式下载回购
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 /少/ 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repo的内容

应该这样做！有两点需要注意：

当我实施此解决方案时，我使用的是ruby 1.9.3-p385
用步骤2中repo的内容替换/Users/ftiasch/.rvm/gems/ruby-1.9.3-p374/gems/less-2.2.2/的内容，对我来说没有用。如果这样做会很好......

lessc编译bootstrap时，“#grid＆gt; .core未定义”
