Error with new expo release 46.0.0

Expo SDK
1

Please provide the following:

  1. SDK Version: 46.0.0
  2. Platforms(Android/iOS/web/all): web
  3. Add the appropriate β€œTag” based on what Expo library you have a question on.

I used to make web app with expo SDK 45.0.0 where everything where right :+1:.
But After creating a new expo app via npm, yarn or npx I got an error that said " can’t not found react " and then another error: with chokidar lock or busy.
When I looked at my previous project in the package.json i found things were different from SDK 45.0.0 and 46.0.0 so maybe the problem come from that.

Hi @kajc

Please show what commands you ran when you got those errors and also the full error output?

Also, what differences did you find between the old app and the new one?

Also, did you perhaps try upgrading the SDK 45 app to SDK 46?

Hi @wodin, thank you for reply.
I ran expo start but i got several times the same issues even when i tried with yarn start
or npm start.
I have a project from the sdk 45 that correctly works using all these commands but when
i used these commands with the new project i began with the new sdk 46, i got a lot of
errors :
