try use @import is not working。

Mentioned error can be caused by different factors. Firstly, provided webpack.config does not include any loader for .less css-files, so ensure to add appropriate loader into config: https://github.com/webpack-contrib/less-loader
Secondly, styles can be wrapped in independent namespaces, which is useful to avoid collisions between components - so ensure, that generated scope is used property
