Angular npm start error

[barrantesj1952]

when I try to run the application with npm start I got an error.
Searching in google I found a solution "delete node_modules", "npm install" but I keep getting the error below.
roberto@Administrators-MacBook-Pro APM % npm start

[email protected] start /Users/Shared/Previously Relocated Items/Security/Repositories/TypeScript/GettingStartedRB/APM
ng serve -o

The serve command requires to be run in an Angular project, but a project definition could not be found.

A few things to try:

Things to try:

1. Did you run npm install successfully? The project files must first be installed before you can use npm start to start the project.

2. Ensure that there is a package.json file in the folder.

3. Try cleaning your npm cache:

• Run npm cache verify
• Delete your node_modules folder and package-lock.json file (if they exist in the project folder)
• Run npm install again.

4. If that doesn't work, double check your version of npm. Ensure you install the LTS version of node (with npm) and not the "current" version, which seems to have more issues. Then repeat npm install not working #1.
   NOTE: I have node v12. Looks like you have v10. Though the Angular docs say "node": ">= 10.13.0", so your version should work.

5. I've heard that some people with very long paths to the Angular files have had trouble in the past: /Users/Shared/Previously Relocated Items/Security/Repositories/TypeScript/GettingStartedRB/APM You could try moving the code to another folder with a shorter path and then repeat npm install not working #1.

Let me know if any of these options worked for you.
All the best -
