Updating dependency by ng update causing error

[ren276]

Bug Report

ERROR

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.
