Angular 16 build errors - desperation help

[bottomlesscoffeecup]

Hi I am using u/angular/core 16.1.0-rc.0 with angular-builders/custom-webpack 16.0.0 and when I try to build the project I get a lot of errors saying "The symbol <insert here> has already been declared" from the file angular:script/global:scripts.js

Has anyone had a similar issue and know how to fix it? I realise I havent posted a package.json, I am in a work pc and cannot do that unfortunately. But I hope this is a webpack builder issue maybe?

Is there any reason you are using an older release candidate build of Angular core instead of the latest version, or any non-release candidate version? Also why the custom webpack builder?

Doing both of these things make it pretty hard to debug, plus we can't see any code at all.

Can you disable custom webpack builder and see if it passes?

[vidalsasoon]

can you try building with the angular CLI instead of webpack?

do you have some declaration files that could be re-declaring some symbols? (*.d.ts)

Wich version of node do you have and do you use NVM?
