"__webpack_require__ is not defined"

[id-pogni]

Browser console logs: __webpack_require__ is not defined in development mode. This issue does not occur in production builds.

Adding a devtool configuration to webpack.config.base.js, like devtool: 'inline-source-map', resolves the issue.

I just download master and tested npm start two different versions of Node, and I wasn't able to reproduce the error.

Have you added/updated any dependencies to your setup? Have you modified .babelrc?

Can you check if there's a .babelrc file somewhere in a parent directory that doesn't look like the one defined here: …/main/webpack.core/.babelrc? For example, do you have such a file in …/main/ in addition/instead of the one in …/main/webpack.core/?

Is this perchance not because of the minifier? I fixed the error by adding
jsProcessor="[default:none,min:gcc;languageIn=ECMASCRIPT_2015;compilationLevel=whitespace]" to the clientlib .content.xml.

You're right @maximus8891, this is GCC related. Thank you for the fix suggestion
