My current project involves using Metronic for React. I've installed the theme and everything is working just fine, including any new pages I've added (or removed) but Visual Studio always shows hundreds of deployment errors.
I tried starting with both yarn and npm. Both work, both produce the same number and type of errors.
Your case depends on your plugins systems and your configuration in IDE, not sure how we can help you with this. Also, pay attention that your mentioned errors are from
node_modules, try to check all your plugins settings and add
node_modules into all ignore lists.
