"ng update --all" typescript error!

[paulober]

If i run "npm install" in the angular project, i got following error:

npm WARN @angular/[email protected] requires a peer of @angular/[email protected] but none is installed. You must install peer dependencies yourself.
npm WARN [email protected] requires a peer of ajv@^6.9.1 but none is installed. You must install peer dependencies yourself. 

An if i run ng update --all i got following:

Package "@angular/compiler-cli" has an incompatible peer dependency to "typescript" (requires ">=3.1.1 <3.3", would install "3.3.3")

Can you help me please, because i am not so familiar with npm and nodejs.
