我正在尝试按照volume-leaflet说明将these通过氦气添加到Apache zeppelin（0.7）。尝试启用它时出现此错误：
./~/leaflet/dist/leaflet.css
Module parse failed: /usr/hdp/2.6.0.3-8/zeppelin/local-repo/vis/node_modules/leaflet/dist/leaflet.css Unexpected token (3:0)
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected token (3:0)

任何人都可以指出我正确的方向吗？
