Have you had issues moving from angular-cli beta 28.3 or earlier to the newer versions of the CLI?

Try these steps then!

Global Dependency

This one is as easy as:

npm rm -g angular-cli @angular/cli
npm cache clear
npm i -g @angular/cli

Specific Project

Note: You do NOT need to have the CLI installed globally for this (although it’s a good idea).

First, ensure you have an npm script in your package.json file that looks like:

"scripts": {
    "ng": "ng"
    // ....
}

In this tutorial I’ll replace ng calls with npm run ng -- (note final space ) for those people who may not be able to upgrade their global package.

Now, let’s get to real work.

Commit everything you have in git, then:

npm rm angular-cli @angular/cli
npm cache clear
rm -rf node_modules
npm i -D @angular/cli
npm run ng -- update

Accept all files from update (which used to be called init) other than app module and component, especially (but not limited to) angular-cli.json, polyfills.ts, package.json and main.ts.

Then go to git undo any unwanted change (deleted packages from package.json, missing scripts or files from angular-cli.json, etc). Undo entire app module and component files if you accepted them by accident.

Then

npm install
npm run ng -- build

And you can go roll with npm start / npm run ng -- serve.

All good!

How did I learn that?

As a bonus for coming here, I'm giving away a free newsletter for web developers that you can sign up for from here.

It's not an anything-and-everything link list. It's thoughtfully collected picks of articles and tools, that focus on Angular 2+, ASP.NET (4.x/MVC5 and Core), and other fullstack developer goodies.

Take it for a test ride, and you may unsubscribe any time.
