我运行时出现以下错误lessc bootstrap.less

我发现了这个问题。但我已经将我的lessc 升级到1.3。

这是版本：

lessc -v

lessc 1.3.0 (LESS 编译器) [Ruby] 2.2.2

引导源文件是从 github 克隆的。

我们需要升级 less 到 1.3.3 版本。

示例（如果您在 node.js 中运行较少）

sudo npm install -g less

我找到了解决办法！

  1. 转到less.js 存储库并将存储库下载为 zip 文件
  2. 转到less.rb repo 的这个分支并将 repo下载为 zip 文件
  3. 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 中存储库中该文件的版本（lib/less /loader.rb)
  4. 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：

  1. 当我实现这个解决方案时，我使用的是 ruby​​ 1.9.3-p385
  2. 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 的内容对我不起作用。要是真的就好了...
