Hi @mbaljeetsingh,

Are you using an NPM cache or private registry? This should happen if you're installing version 5 of Material. Version 6 is latest right now so this should work.

I have similar issue

When I try to add schematics one more time it becomes even weirder :D

On this config it works fine :

[danzrou]

Same here with ng add @angular/material

@dtomaszewski I also had this error, simply adding the package manually resolved the problem

yarn add @angular-devkit/schematics --dev

[mbaljeetsingh]

One solution I found is, If you install @angular/material and @angular/cdk dependencies locally before running ng add command, then it seems to work.

npm install --save @angular/material @angular/cdk
ng add @angular/material

Note: ng add @angular/material command working fine on my other machine with the same node, npm and angular cli version.

@eyev this solution does not work for me, however @mbaljeetsingh solution with manual install before ng add works as a workaround

@mbaljeetsingh the solution worked for me. Thanks!!

I am facing same problem with ng add @angular/material. Error: Collection "@angular/material" cannot be resolved.

[Shraddha80011]

Temp solution, use old version ng add @angular/material@6.2.1

[kernelgis]

The solution is to indicate the version, it works for me like this: ng add @angular/material@6.3.0

So I had a similar issue regarding material not working and getting the "typerror some function not defined". Fix

1. Run ng update in project console ( shows what can be updated )
2. ng update filename to update
3. npm install (this step is actually what I was missing after updating @angular/core)
4. ng serve (rerun your project and that should work (that's how I fixed my issue))

Please let me know if I need a more thorough explanation!

I followed this process to update my project first. https://www.techiediaries.com/updating-angular-cli-projects/ because "ng add" is a feature of angular 6 but in my project, as it is running angular 5 so the main file 'angular.json' file was missing. And that is why "ng add was not working in my project".

When I was installing ng-zorro-antd, I had the same issue. What I did was, deleted the node_module and install it again. After that, I run ng add ng-zorro-antd, and got an warning: I found the lines it remind me, and corrected ‘targets’ to 'architect', run ng add ng-zorro-antd again, success!!

what's the best version of angularMaterial compatible with angular 6 ?

I just tested ng add @angular/material using the latest Angular CLI in a brand new project and it worked just fine.

The initial report is almost 2 years old and the last comment is unrelated. I think that this can be closed.

@JigmeLodey, you should never use the Angular CLI (or npm for that matter) while logged in as the root user. If you still encounter the error, you should create a new issue, but make sure that you read the Submission Guidelines.

[mbaljeetsingh]

This actually works with the latest version of Angular. So closing it.
