Upgrade Angular

To upgrade angular to its latest version, perform the following commands on a Terminal window:


npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@latest

You can also install a specific version, by typing the version number as follows:


npm install -g @angular/cli@<version-number>

Install a new version of Node.js and Angular

If you have installed Node with NVM, you can upgrade Node and Angular at the same time.


First, install a new version of Node:


nvm install node

Then install a new version of Angular:


npm install -g @angular/cli

With this method I have installed Angular 7 with Node v11.14.0, and Angular 8 with Node v12.4.0:


~/.nvm
   └─ versions
      └─ node
         ├─ v11.14.0
         │  └─ lib
         │     └─ node_modules
         │        ├─ @angular (version 7)
         │        └─ npm
         └─ v12.4.0
            └─ lib
               └─ node_modules
                  ├─ @angular (version 8)
                  └─ npm

Then using NVM you can switch between each of the installed versions.
