No "exports" main resolved in @babel/helper-compilation-targets/package.json

Bug Report

Current Behavior Since an update to node 13.10.1 I have a problem while building an application with babel-loader:

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

Expected behavior/code It should build correctly

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

Solution

If you hit this issue from search engines, please update all @babel deps to v7.8.7 or above.

I fixed this issue by removing the node_modules directory and package-lock.json file then run npm install to fresh install all packages then the issue was fixed.

@JamesSingleton Upgrading the packages to 7.10 fixed the issue for me.
