No “exports” main resolved in @babel/helper-compilation-targets/package.json with Node 12.17.0

Bug Report

I know #11216 mentions a similar issue, but that is with Node 13, this is with the newly released 12.17.0.

Current behavior

Node just released 12.17.0 and now running "build": "babel src -d ./", with the following deps (also installed the latest versions as well and still had the issue)

"@babel/cli": "^7.8.3",
"@babel/core": "^7.8.3",

results in:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main resolved in /Users/singleton/OSS/holocron/node_modules/@babel/helper-compilation-targets/package.json

Input Code

"build": "babel src -d ./",

Expected behavior

It should build properly without error as it does on Node 12.16.3.

Babel Configuration (babel.config.js, .babelrc, package.json#babel, cli command, .eslintrc)

  • Filename: babel.config.js
module.exports = function (api) {
  return {
    babelrcRoots: ['.', './packages/*'],


    OS: macOS Mojave 10.14.6
    Node: 12.17.0 - ~/.nvm/versions/node/v12.17.0/bin/node
    npm: 6.14.4 - ~/.nvm/versions/node/v12.17.0/bin/npm
    Lerna: 3.20.2
    @babel/cli: ^7.8.3 => 7.8.3 
    @babel/core: ^7.8.3 => 7.8.3 
    babel-preset-amex: ^2.1.0 => 2.2.0 
    eslint: ^6.8.0 => 6.8.0 
    jest: ^25.1.0 => 25.1.0 
    lerna: ^3.20.2 => 3.20.2 

Additional context
It works fine on Node 12.16.3.

  1. In my case, the @babel/helper-compilation-targets package is installed as a dependency of @babel/preset-env. Updating it to the latest version fixed the issue for me.

    $ npm ls @babel/helper-compilation-targets
    └─┬ @babel/preset-env@7.8.3
      └── @babel/helper-compilation-targets@7.8.3
