+If the output reports an error like `Cannot find module 'http'` at browser runtime, it means that your output has bundled node modules.
+This may occur if some of your dependencies support both browser and node, such as `axios`, in which case you only need to set the [platform](/api/config/build-config.html/#platform) to `browser`.

+如果一些三方包不支持 browser, 你可能需要手动注入 [node polyfill](/plugins/official-list/plugin-node-polyfill)。
