SDK Version:40
Platforms(Android/iOS/web/all): Android/iOS

Hi, I am getting this warning after upgrading to Expo 40:

Your project is accessing the following APIs from a deprecated global rather than a module import: Constants (expo-constants).

The global “__expo” and “Expo” objects will be removed in SDK 41. Learn more about how to fix this warning: fyi/deprecated-globals.md at main · expo/fyi · GitHub

I did found some discussions about, but I any of them helped me getting rid of it. Is anyone willing to assist?

I have search for “__expo” on my project (and modules) but there is any reference…

Here are my modules:

Hey @thorapps, I would recommend clearing your caches (either npm or yarn) depending on what you use and then run expo start -c.

Cheers,
Adam

Hi,
thanks for your reply… however it did not work…

antoniokokoen · February 10, 2021, 3:02pm

I believe the problem is on react-native-reanimated. There has a variable with global.Expo inside a if.

thorapps · February 11, 2021, 10:13am

You are right…react-native-reanimated was one of the culprits… searching for globals.Expo found some more (SafeAreaView which is widely used on other modules):

I upgraded to reaanimated 2.0.0rc0 but still same problem…
I upgraded also native-base which used SafeAreaView… no luck either.

Here is my current package.json:

  },
  "devDependencies": {
    "@babel/core": "^7.12.13",

  },
  "private": true
}

I removed node_modules and cleared cache…

What can I do?

Have you been able to fix this issue? I’m having the same problem.

thorapps · March 5, 2021, 5:34pm

No, I did not solve it. If you find a solution, post it here
