[ng update]: Error - The "@angular-devkit/schematics" package cannot be resolved from the workspace root directory

Question

ng update

The "@angular-devkit/schematics" package cannot be resolved from the workspace root directory. This may be due to an unsupported node modules structure. Please remove both the "node_modules" directory and the package lock file; and then reinstall. If this does not correct the problem, please temporarily install the "@angular-devkit/schematics" package within the workspace. It can be removed once the update is complete.

If you search for `@angular-devkit/schematics` using your IDE does it exist anywhere other than package-lock.json? — Andrew Allen, Mar 05 '20 at 14:15

I had this issue

First I ran this to see the structure of the package

npm ls @angular-devkit/schematics

it returned....

Mms@0.0.0 C:\Users\wgrant\source\repos\WD\MMS\Mms\ClientApp

`-- (empty)

since it was empty I ran the following (if yours is not empty maybe try update instead of install)

npm install @angular-devkit/schematics

and after this, the 'ng update' ran successfuly

I am trying to go from angular 11 to 12 to 13 and getting stuck on the 11 to 12 step. Other libraries are complaining .. – ScipioAfricanus Mar 05 '22 at 20:15

In my case, I needed to just run

npm install

then the command

ng update @angular/core @angular/cli

completed successfully

In my case, I was running the ng update command in a directory which didn't have the package.json. Running the command in correct directory fixed it for me.

Just Create New Project by using ng new prjName.
Check for @angular-devkit/schematics if not found then run npm install @angular-devkit/schematics
It will install @angular-devkit/schematics if finds any vulnerability just fix them by npm audit fix
Just hit ng update @angular/cli@^10 @angular/core@^10 for specific version (here for version 10) or just run ng update
npm cache clean --force
ng update
