What is the difference between babel-core and @babel/core ? Are they the same thing but different versions? If not so, when do you use one and when do you use the other? Thank you. Since Babel 7 the Babel team switched to scoped packages , so you now have to use @babel/core instead of babel-core . But in essence, @babel/core is just a newer version of babel-core . This is done to make a better distinction which packages are official and which are third-party. 来源： https://stackoverflow.com/questions/53380741/what-is-the-difference-between-babel-core-and-babel-core

Need some help, I'm getting a weird error out of left field that I have not been able to debug. This project was bundling successfully until yesterday after I setup my react native project on another Mac. I'm wondering if it's from versioning of npm packages I had to reinstall. Any direction would be helpful, it's always the setup that's the hardest because you do it so infrequently... My babelrc file is as follows -- { "presets": ["babel-preset-expo"], "env": { "development": { "plugins": ["transform-react-jsx-source"] } } } And my package.json { "name": "hancho_frontend", "version": "0.1.0",

I have 2 Vue-Cli webpack projects (ClientApp and Lib). Lib is my components library (shared with other projects) Problem When I build my project ClientApp npm run build , I have the following error: ERROR in static/js/app.d08a24ce0e8d0438ce68.js from UglifyJs Unexpected token: operator (>) [C:/.../Lib/src/tools/escape-key.js:3,0][static/js/app.d08a24ce0e8d0438ce68.js:17468,38] Questions It seems like the error comes from an arrow function in the file escape-key.js . This is ES6 syntax and UglifyJS can't parse this. Shouldn't Babel go first, before Uglify? Note that is works well with *.vue

Why its not accepting spread properties ? I am using babel-preset-env for this. .babelrc { "presets": [ "react", [ "env", { "targets": {}, "debug": true, "modules": "commonjs" } ] ] } package.json { "name": "myapp", "version": "0.1.0", "main": "index.js", "private": true, "dependencies": { "babel-core": "6.25.0", "babel-loader": "7.1.1", "babel-preset-env": "^1.6.0", "babel-preset-react": "^6.24.1", "extract-text-webpack-plugin": "3.0.0", "file-loader": "0.11.2", "html-webpack-plugin": "^2.30.1", "moment": "^2.18.1", "react": "^15.6.1", "react-dom": "^15.6.1", "react-router": "^4.1.2", "react
