Class constructor FileManager ca

启动项目显示如下错误

Failed to compile.

./src/theme/recss.css
Module build failed:

Class constructor FileManager cannot be invoked without 'new'
      in undefined (line undefined, column undefined)

解决方法：

• 把 package.json 的 devDependencies 依赖 less 版本锁定在 3.9.0 即可。 issues
• 删除 node_modules，重新 npm install
