fix: remove specific version of typescript from dependencies

[Hotell]

Suddenly all my builds started to fail https://github.com/Hotell/typescript-lib-starter/pulls

The culprit here is typedoc becuase it has specific version of typescript as direct project dependencies which overrides local node_modules/.bin/tsc symlink to use this TS instead of TS that is used by the project.

This is a big deal.

How to fix this:

• move typescript to peerDependencies ( best solution ) ( this would be a breaking change for your library from perspective of semver )
• change typescript version in your depencies to ^2.3.4

I can submit PR if you're willing to go through it and merge it eventually after LGTM :)

We have a PR #549 open to update TypeScript to 2.4 but work does need to be done to make the TypeScript dependency less brittle.

For reference, this has been discussed mainly in #145 (though also noted in #369).

There is also some relevant discussion in #310

all right, so I found out in the end that the culprit is yarn !!! wooot :(

sorry for bugging you folks.

yarnpkg/yarn#3983

I'm going to close this for now. If you have it in your own dependencies it certainly shouldn't replace it. That's the reason we use dependencies - we have a specific version requirement for TypeScript and we can't just use any version today. As a result, we can not use peerDependencies or have it automatically use later versions.
