问题 Babel 7.2.0 I need to transpile my JS-files and combine they into single result file. This is my attempt: npx babel --source-root src/index.js --out-file lib/result.js --minified --presets @babel/preset-env But I get the error: babel: stdin compilation requires either -f/--filename [filename] or --no-babelrc I tried -f and --no-babelrc but it doesn't help me... 回答1: Your current command never tells Babel what file to compile, so it is expecting the file content to come from stdin.

问题 I am trying to modify a react native boilerplate so that I can be run on Android platform. I installed the expo package and added an index.js file on the root directory.

问题 I have a React, Electron app that I wish to be able to access native node modules from the ES6 compiled (using Babel and Webpack).

ERROR in ./src/app.js Module not found: Error: Cannot resolve module 'fs' in C:\Users\Propietario-1\Documents\GitHub\AMPLI @ ./src/app.js 1:358-371 But when I required this from a "none compiled" js file it works.
