Hi,

If I try to update bootstrap from "bootstrap": "^3.3.7" to "bootstrap": "^4.1.1", then all the routing in angular breaks. It says "Cannot GET /" for every url query type.

I want to update it because all of the code snippets in the bootstrap documentation currently are not working. I want to use the navbar component but it looks like a mess and I thought this was because the bootstrap documentation examples use bootstrap 4.

Is there a safe way to update bootstrap using the ASP.Net Core 2.1 angular template? I cannot find any other error message so I'm not sure why exactly it does not work.

Has anyone else ran into this problem before?

EDIT: Found an error but not sure how to fix it:

webpack: Failed to compile.

Microsoft.AspNetCore.SpaServices:Error: ERROR in ./node_modules/bootstrap/dist/css/bootstrap.min.css
