Je viens de passer à Babel 7 (à partir de 6) en exécutant ces commandes:
npm remove babel-cli
npm install --save-dev @babel/cli @babel/core @babel/preset-env
Voici mon fichier .babelrc
{ "presets": ["env"] }
Puis j'ai couru:
babel js/src --out-dir js/dist
Et cela se traduit par:
TypeError: Cannot read property 'bindings' of null

Qu'ai-je fait de mal?
