angular - Error: Please, upgrade your dependencies to the actual version of core-js@3

Question

I'm trying to run npm start but giving me error "An unhandled exception occurred: Could not find module "@angular-devkit/build-angular" I also tried to install it by using npm install @angular-devkit/build-angular but still getting me an error.

Error "npm WARN deprecated core-js@2.6.11: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3."

How can I upgrade my dependencies?

Answer 1

You should be able to simply update the version of the core-js module that is requested within the warning message:

npm install --save core-js@^3

For what it's worth npm has a nifty feature that lets you see which packages are outdated

npm outdated

You can also update packages to the latest versions using the update command
