Couldn't find package "typescript" on the "npm" registry.

[innabelov75]

Following the instruction on setting up the project, observed the following issues:

1. running yarn command did not update yarn.lock file as mentioned at @6:00 of the first lesson
2. running yarn build inside packages/types produced an error: "Couldn't find package "typescript" on the "npm" registry."

I was finally able to resolve the issue by editing ~/.npmrc to include registry=https://registry.yarnpkg.com, and also adding a local .npmrc file inside the js-ts-monorepos project with the same content.
