Babel没有从JSX转换为JS，在没有使用webpack / browserify / bower的情况下手动尝试

Question

I am trying basic example in React.JS and using Babel to transpile from jsx to js. I hope I installed all babel dependencies, shown in package.json below. Also added App.jsx and index.html pages.

As shown in line 8 of package.json, I am trying to execute babel with "npm run build" but it is throwing error as shown in this terminal screenshot.

Any help appreciated.

Answer 1

This happens when you don't configure Babel (properly).

Add this to your package.json :

"babel" : {
  "presets": ["es2015", "react" ]
}
