通过插件市场 下载zip包然后 解压放在 指定目录下（/Applications/HBuilderX.app/Contents/HBuilderX/plugins/）重启hbuilder
无效
之后进到less插件目录下发现只有 json和md 2个文件，没有依赖文件夹。然后 sudo npm i 安装less依赖。
安装后提示如下：
···
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN less@1.0.4 No repository field.
npm WARN less@1.0.4 No license field.
···
重启hbuilder 后还是有错误
之后卸载重装插件，包括安装低版本hbuilder(2.8.3)也是同样的报错误
