pragma has been set but pragmafrag has not been set

🐛 bug report

Can't use React Fragments.

🎛 Configuration (.babelrc, package.json, cli command)

Default babel config

🤔 Expected Behavior

React Fragments should be supported by default.

😯 Current Behavior

Using Fragments will make babel throw error

💁 Possible Solution

https://github.com/parcel-bundler/parcel/blob/master/packages/core/parcel-bundler/src/transforms/babel/jsx.js#L45

should set the pragmaFrag for React.

In the meantime adding this to your babel plugins solves it:

["@babel/plugin-transform-react-jsx", {
  "pragmaFrag": "React.Fragment"
}]
