问题
Just updated react to 0.13.3 and now I get the following message in Chrome react developer tool: "waiting for roots to load...to reload the inspector" and a button saying "click here".
And if I click the button, same thing again.
FYI: I am using WebPack & webpack-dev-server.
Have you seen this?
回答1:
This error is generally linked to modules not loading into the project correctly, but the cause of this when the react syntax is incorrect. Generally, it's a missing semicolon after return statements (easy to miss).
I've confirmed this using reacts tutorial, writing it out myself, seeing this error, then commenting mine out and replacing it with the script including example.js

Updating my loader worked:
module: { loaders: [ { test: /.js$/, exclude: /node_modules/, loader: "babel-loader"} ] }

Check your imports and exports of each of your component files. I had this same error because I forgot to export a component to my index.js file.
