Bug Report

Current Behavior

I've installed babel in a separate directory /tools, which is not where my project lives. Trying to run babel fails with

$ /tools/babel source.ts 
{ Error: Cannot find module '@babel/plugin-proposal-class-properties' from '/my/project'
    at Function.module.exports [as sync] (/tools/lib/node_modules/@babel/core/node_modules/resolve/lib/sync.js:58:15)

Expected behavior/code

Babel should just load the plugins from where babel is installed, and not override the module resolution base dir with cwd. I don't understand why you would want that, ever. If there is a use case (is there?) then at least catch and try again without overriding the base dir.

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

My .babelrc is just

    "presets": [
    "plugins": [

and all required packages are installed under /tools


  • Babel version(s): 7.2.0
  • Node/npm version: Node v10.12.0, npm 6.4.1
  • OS: Fedora 29 x86_64
  • How you are using Babel: cli

Possible Solution

Plugins load fine if, in resolveStandardizedName, I replace

        resolve.sync(name, { basedir: dirname });



Note that dirname is set to cwd (as absolute path), and there does not seem to be a way to override it from .babelrc.

Is there any way to edit or override the default cwd? Maybe an option in webpack.config,js?
I read the code, but i can not find any way to edit it.
