Question

I need to change this topic, I cant post new topic. I have update the script, and install new package. I still get errors but not the one I post last.

Answer 1

Angular 6 looks for angular.json instead of angular-cli.json.

You need to update your @angular/cli. Adding to the above answer

I did update all the package with the following commands and updated all dependencies too. So as to remove all compatibility issues with other packages.

If you are starting your app or demo app, follow this procedure. Be extra careful if you are doing this for production app.

npm install -g npm-check-updates
ncu -u
ng update @angular/cli
npm install

Install npm-check-updates

npm install -g npm-check-updates 

Use ncu to update your package.json

ncu for display

ncu -u for re-writing your package.json

Update your @angular/cli to modify your application to be compatible with angular 6

ng update @angular/cli 

and run npm install to update your packages

Answer 2

That seems to be caused by different version of angular-cli is installed. I just created a new project, using new command, then copied across the src directory. then compiled them all successfully.

    ng new UX7

Answer 3

I would recommend reading this:

https://www.techiediaries.com/updating-angular-cli-projects/

On this page it states:

Angular 6 uses angular.json instead of angular-cli.json. This can be achieved using :

ng update @angular/cli

This solved my issue.

Good luck

Answer 4

Re-Install @angular/cli

npm install @angular/cli

Answer 5

Just use the official upgrade guide which will tell you what you need to do for your own particular needs:

Answer 6

In my case I just needed to close/reopen my terminal after I had remove/reclone a repo. Not sure what happened there.
