Hi @i_sapumal. Did you find the solution for this? I'm stuck with the exact same error. Thanks! – Hale

I'm stuck on a similair issue trying to upgrade from Angular 11 to 12. Migration failed: Could not find any tsconfig file. Cannot migrate `ActivatedRouteSnapshot.fragment` accesses. Same question did you find a solution? – Thorn

Answer 1

In order to run the migrations you need to install the @angular-devkit/core package

npm i @angular-devkit/core@<VERSION> -D
ng update --from <FROM_VERSION> --to <VERSION> --migrate-only --allow-dirty --verbose @angular/core

After migrations you could remove the package again.

I got the same error upgrading from angular 8 to 9. I had a tsconfig file in my project and it was linked well. In my case the error was caused by the @angular-devkit/schematics package. I resolved the error by the following steps:

1. remove the package @angular-devkit/schematics from your package.json
2. delete the node_modules and package-lock.json
3. npm i (I need to execute npm i --legacy-peer-deps - but be careful with that)
4. npx @angular/cli@9 update @angular/core@9 @angular/cli@9

Let me now if this worked. Hope this might help someone

This worked, although for step 1 you can do: npm uninstall @angular-devkit/schematics and skip therefor step 3. Thanks for your help – Advisee

Answer 3

It says cannot migrate to dynamic queries please try the below code

npx @angular/cli@9 update @angular/core@9 @angular/cli@9 --force

I tried this solution above and it does not work. This just forces Angular to use packages with un resolved dependencies. It did not correct this issue for me. – Thorn

When I was hit with this error. All I had to do was, run; 'ng update'. I was given the suggestion what to do next. Attached for reference below;

In my case I had to run as suggested; 'ng update @angular/core@12'

For me the issue was my version of node. v12.22.12 worked for me.
