Typescript is invalid

I upgraded angular to 4 and angular cli to 1.03. After I run the command npm ls typescript I get:

+-- @angular/[email protected]
| `-- [email protected]
`-- [email protected]  invalid

npm ERR! invalid: [email protected] C:\development\projects-git\mydoc\static-web\node_modules\typescript

What's the difference between the first and the second typescript, why is the second one invalid/how do I fix it?

I think the error above is the reason why I get the error below so I hope there is a fix for both so I can run my application again.

ERROR in AppModule is not an NgModule
ERROR in ./src/main.ts
Module build failed: TypeError: Cannot read property 'newLine' of undefined

I had a similar issue where i even had two different typescript versions listed when i did npm ls typescript.

What's the difference between the first and the second typescript

The first one is listed as a dependency of @angular/cli, the second one is a dependency of your own project.

why is the second one invalid/how do I fix it?

In my case, i had typescript defined under both, dependencies and devDependencies section in my package.json. I removed it from dependencies and the duplicate output disappeared.
