Codesandbox: "Cannot find module 'rxjs'"

[josepot]

Bug Report

Current Behavior
When creating a new Sandbox on codesandbox.io, while using the latest Vanilla TS template (which uses typescript@4.2.3) I'm unable to import anything from rxjs because I get the following error:

Cannot find module 'rxjs' or its corresponding type declarations.ts(2307)

I guess that there must be a setting on the tsconfig that needs to be setup, but I can't find any mention to that on the docs of the breaking changes.

Reproduction

https://codesandbox.io/s/dawn-glitter-s1rdb?file=/src/index.ts

Environment

• RxJS version: 7.0.0

Additional context/Screenshots

rxjs@7.0.0-rc.3 doesn't have this issue.

If 7.0.0-rc.3 doesn't have the problem, I doubt it.

7.0.0-rc.3...7.0.0

My bet is that it's another problem that relates to: #6276

I'm closing this, because it's the same as #6350
