I'm running into this same problem. Why was this issue closed? Is there a fix?

My bundle command: browserify -t babelify -t unassertify -t envify -p common-shakeify -p browser-pack-flat -p bundle-collapser/plugin v1/index.js | uglifyjs -cm >

Browserify-Version: 7.0.0 Bundle-Collapser-Version: 1.4.0 Acorn-Version: 7.4.1

As a side note, this only became an issue for me when upgrading babel/core from 7.22.9 to 7.25.2.
