問(wèn)題解答

需要添加 json loader

如果你的代碼同時(shí)需要在瀏覽器端和node端運(yùn)行，建議使用 isomorphic-fetch，兼容兩個(gè)平臺(tái)

I received this same exact error. You’ll want to install a JSON loader module. I’m using json-loader in this example.

npm install json-loader --saveThen, you need to add this loader to your webpack.config.js

module: {

loaders: [ { test: /.json$/, loader: 'json-loader'}]

}
