create-react-app failed to compile

See original GitHub issue

Current behavior:

When npm install @emotion/core and/or @emotion/styled after setting up a typescript project with create-react-app the app failed to compile even though I didn’t import emotion in the project.

To reproduce:

npx create-react-app vz-app --template typescript
npm install --save @emotion/core @emotion/styled

Expected behavior:

Should render the create-react-app landing page correctly.

Environment information:

react version: 16.12.0
@emotion/styled version: 10.0.23

I think this just is caused by a fact that you install extra dependencies with npm, while the existing node_modules has been created with yarn. It’s some kind of a mismatch between those 2 installs - if I remove all node_modules & lock files and do a fresh npm install (which includes already added emotion dependencies) then everything works OK.

npm i @types/react and npm i @types/react-dom removing the error.
