Node.js Question

Update npm to @angular 2 is not available

I want to upgrade from angular 2 Beta 15 to angular 2 RC1.

I am using Visual Studio 2015.

In my npm package.json inside Visual Studio I do:

"dependencies": {
"@angular/core": "Unavailable",

but I get unavailable.

Then I did some updates:

I updated my nodejs to v6.1.0.
I updated my npm to v3.8.9.

It still shows unavailable in Visual Studio 2015.

What can I still try to make it work?


After doing what @David Pine suggested I got this error:

I also added the correct path to nodejs in my Visual Studio options see:

Answer Source

Ensure that Node.js is at the top of the external web tools paths in Visual Studio, detailed here.

I have found that Visual Studio 2015 can be unreliable in terms of integrating with npm. Instead of relying on VS to update it for you, open up the package.json and manually enter the version you're looking for.

Instead of:

"dependencies": {
    "@angular/core": "Unavailable",


"dependencies": {
    "@angular/core": "2.0.0-rc.1",
