What is the expected behaviour?
Should compile without errors and console log.
Which package versions are you using?
"babel": "^6.23.0",
"babel-plugin-flow-runtime": "^0.15.0",
"babel-plugin-transform-decorators-legacy": "^1.3.4",
"babel-preset-react": "^6.24.1",
"babel-preset-stage-0": "^6.24.1",
"babel-preset-stage-2": "^6.24.1",
"babel-register": "^6.26.0",
"flow-runtime": "^0.16.0"
The fix is to simply add babel-preset-env
.
{
"presets": [
"env",
"stage-2",
"react"
],
"plugins": [["flow-runtime"], "transform-decorators-legacy"]
}
and
npm install --dev babel-preset-env
