react ts app yarn test:unit fails with SyntaxError: Cannot use import statement outside a module

[pnwcoder2020]

Thank you for your work on this package and apologies in advance if this issue is the result of user error.

I see the following error in the example react-app-ts and also when incorporating vite-jest into my own react app.

/code/vite-jest/examples/react-app-ts/node_modules/vite-jest/bin/vite-jest.js:3
import fs from 'fs'
^^^^^^

I am getting a very similar issue specifically when testing React components following the same example. In this case, react-hook-form seems to be the offender.

I can post more details if that is helpful

Maybe more related to #11 though now that I read through it

Edit: for clarification this is using npm v7.19.0

I think this is a Yarn 2 specific problem, and to be more specific this is because Yarn 2 cannot currently run ES Modules.

See yarnpkg/berry#638

When I try to run the example with pnpm it works, but not using yarn

@mijamo The error in my screenshot was with npm v7.19.0. I have not tried pnpm, although I did observe the same issue with Yarn 2 as you indicated as well.
