Angular 7 “expected 'styles' to be an array of strings”

Question

I am trying to run my server and have my app.component.html load on localhost:8000. Instead, I am receiving this error

compiler.js:7992 Uncaught Error

Answer 1

I had the same console error, spent a few days reading every hit on Google...

Solved!

The story: I had to add functionality to an existing Angular project. When I performed git clone, ng serve, open browser -> error assert....

I decided to upgrade to Angular 8 and see if the problem goes away, and it didn't. Eventually, I created a new Angular 8 app using "ng new ..."

Compared package.json and angular.json of both existing and new project. I found out, the brand new Angular app, had no loader packages In package.json, while the existing did have. Also the existing project was specifying a webpack devDependancy, i removed all loaders, and webpack, deleted package-lock.json and node_modules folder -> npm install.

Solved. I guess there is some bit of code that was being forced to a specific version, conflicting with what Angular really needs.
