【HAVENT原创】less version 3.0.4 is not currently supported

最近在一个老 NodeJS 项目中升级了其中一个插件，然后在全新目录 npm install 项目的时候会出现如下错误：

Error: less version 3.0.4 is not currently supported

发现原因：less 的当前版本（3.0.4）对于我的 gulp-less（3.3.2）来说版本太高，需要降级，搜了一下，执行命令

npm install less@2.7.3

less 版本成功降级到 2.7.3 之后完全兼容 gulp-less 3.3.2 了，问题解决！
