Unable to build Angular - "Node.js version v10.6.0 detected."

I am trying to build an angular project which works with Node.js v10.23.1. I have updated Node.js version to v10.23.1. Here are the installed versions on my computer.

Angular CLI: 11.2.2 Node: 10.23.1

When the build command running, I am getting the error below:

[13:56:20] Error in plugin "run-sequence(ng:build-angular)" Message:

Please advice.

Solution

There might be a problem with the Node.js installation, i advice you to remove Node.js from your computer and try to install it again with nvm (Node Version Manager).

This tool let you install multiple versions of Node.js and let you choose which one you want to use, for example in you case you may try install both version 10 and 12 and try to build/serve with those.

nvm install 10
nvm install 12
nvm use 10

Be sure you have the Angular CLI updated globally by running:

npm install @angular/cli -g

You can also try to delete node_modules folder under you project folder and run npm install to reinstall every npm package.
