I want to install ngx-auth-firebaseui.

Mention any other details that might be useful

First time using this package. I'll try installing with npm.

I would like to confirm that I am getting this exact same error.
I thought it might be nvm related so I installed node and disabled nvm but that didn't solve the problem.

Installing via npm isn't an option for me as I plan on changing the things like the user profile page to match my requirements.

When using a different schematics version the output looks different but still gets stuck with a different errror

So this is related to schematics version, I've tried 11.0.3/11.0.2/11.0.1 - Same
Cannot find module '@schematics/angular/utility/json-utils'
Error in all 3
other schematic versions 9/10 gives throws Cannot read property 'defaultProject' of undefined

I want to use this library as well, so I did some digging. Turns out the folks over on the angular/cli repo actually deleted the files. Here is the PR: angular/angular-cli#18875

Given the merge date of Sept 24th, it was probably merged into one of the 11.0 pre-release builds. Which means you would need to use angular/cli 10.x in order for this library to continue to work.

Same issue with Ubuntu 20.04 LTS and schematics 11.0.4. Wanted to use this library which looks super cool !

This library creates a wrapper around json-utils.ts. Since that file has now been deleted from the schematics/angular library. Can it be deleted from this library as well? I looked into the code and as far as I can tell it is not being used by anything.

Minimal steps would be to increase the dependency of schematics/angular from 9.x to 11.0.x and then delete the file.

I'm having the same issue

I tried with @angular/cli & @schematics/angular versions of 10.2.1 and it was able to progress to the "Installing packages..." portion but then it fails with "Cannot read property 'defaultProject' of undefined

[robwatt]

@andresrivero in my personal fork of this repo, I was able to remove the json-utils reference (which worked to remove the main issue), however just as you did, I also ran into the issue of 'Cannot read property 'defaultProject' of undefined. Upon further investigation into this I was able to find where the problem was occurring, but not why.

Inside a typescript file: projects\ngx-auth-firebaseui\schematics\ng-add\index.ts there is a function that handles the imports. It's here where the problem lies.

export function addModuleToImports(options: any): Rule {
  return (host: Tree, context: SchematicContext) => {
    const workspace = getWorkspace(host);
    // @ts-ignore
    const project = getProjectFromWorkspace(workspace, options.project);

    // const x =
    //   `apiKey: 'your-firebase-apiKey',
    //   authDomain: 'your-firebase-authDomain',
    //   databaseURL: 'your-firebase-databaseURL',
    //   projectId: 'your-firebase-projectId',
    //   storageBucket: 'your-firebase-storageBucket',
    //   messagingSenderId: 'your-firebase-messagingSenderId'`;
    const moduleName = `NgxAuthFirebaseUIModule.forRoot(PUT_YOUR_FIREBASE_API_KEY_HERE)`;

    addModuleImportToRootModule(host, moduleName, 'ngx-auth-firebaseui', project);

    context.logger.log('info', `✅️ "${moduleName}" is imported`);

    return host;
  };
}

the function 'getProjectFromWorkspace()' is coming from angular, however, it would appear the package it comes from should be considered an internal package and shouldn't be used incase there are changes.

When I print out the value of 'project', I get undefined. So I don't know where we are supposed to define this project (I tried in the angular.json file, but that didn't seem to work for me). If no value is provided the method sets a default.

function getProjectFromWorkspace(workspace, projectName = workspace.extensions.defaultProject)

I have no idea how the schematics library is defining the value of defaultProject...but it is clear this is the source of the problem.
