+(This may not be a problem any more if you are scaffolding your project using the `webpack` template after [this commit](https://github.com/vuejs-templates/webpack/commit/49456eb8c53252d6d238cc0e27e3bcfd6732e1a5). From now on you can directly import `vue-echarts/components/ECharts` with ease.)
+
+If you are using `vue-cli` to create your project and you want to use the untranspiled component (import `vue-echarts/components/ECharts` rather than import `vue-echarts` directly, to optimize bundle size), the `webpack` template may exclude `node_modules` from files to be transpiled by Babel. To fix this problem, try change `build/webpack.base.conf.js` like this:
+
+```diff
+      {
+        test: /\.js$/,
+        loader: 'babel',
+        include: [
+-          path.join(projectRoot, 'src')
++          path.join(projectRoot, 'src'),
++          path.join(projectRoot, 'node_modules/vue-echarts')
+        ],
+-        exclude: /node_modules/
++        exclude: /node_modules(?![\\/]vue-echarts[\\/])/
+      },
+```
 
-if you are using `vue-cli` to create your project, the `webpack` template may exclude `node_modules` from files to be transpiled by Babel. Change the `exclude` value from `/node_modules/` to `/node_modules(?![\\/]vue-echarts[\\/])/` to fix the problem.
