The ng upgrade command for updating cli version from a v7 project to v8 fails.

Manually trying to upgrade cli first also fails.

ng update @angular/cli

Your global Angular CLI version (8.0.1) is greater than your local version (7.3.9). The local Angular CLI version is used.

Package "@angular/compiler-cli" has an incompatible peer dependency to "typescript" (requires ">=3.1.1 <3.3", would install "3.4.5"). Incompatible peer dependencies found. See above.
