While running this command: rxjs-5-to-6-migrate -p src/tsconfig.app.json I get the following error:

I checked my package.json and I see I have typescript among my devDependencies, and I vlaidated it like this:

$ yarn list | grep typescript
│  ├─ typescript@~2.9.1
│  ├─ typescript@>=2.6.2 <2.8
│  └─ typescript@2.7.2
├─ typescript@2.9.2

I also tried installing typescript globally with yarn add global typescript.

What can be the reason for this error?

Running this, solved the problem: sudo npm i -g typescript I thought that was doing the exact same as yarn add global typescript that I had already executed, but seems not.
