To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

Check out repo & yarn install in root
Navigate to with-typescript example
yarn install
yarn run build

Minimal Fuss Repro™:

git clone git@github.com:zeit/next.js.git
cd ./next.js 
yarn install
cd ./examples/with-typescript
yarn install
yarn run build

Expected behavior

It should build

System information

OS: osx
Version of Next.js: 6.0.3

Additional context

I actually found this issue in my own project - it just stopped building. I tried re-running previously passing builds (yarn.locked dependencies) and it now fails. I guess it’s either a dependency that yarn can’t control, or someone has overwritten a release version somewhere
