Create-react-native-app: Missing script: eject

[LAITONEN]

Description

I have an Expo App (which I have created with Expo, did not recall calling create-react-native-app), which I would like to be able to run both through Expo and with Xcode. So, I duplicated by copy-pasting the Expo App and run npm run eject in the project directory of a duplicate. When I did that, i get the error: missing script: eject

Expected Behavior

I expected being walked through the process of ejecting:

This is usually as simple as running npm run eject in your project, which will walk you through the process.

Observed Behavior

I got the error:

missing script: eject

Hi! This script is created as part of using CRNA. If you install react-native-scripts in your Expo project and copy the CRNA package.json's scripts section, you can probably emulate this.

[LAITONEN]

@dikaiosune Understood. Will try it some time. The app was installed specifically with Expo and I reckoned that it is basically the same as installing using CRNA.

Have the same problem. Just created a fresh project with Expo IDE. Just wanted to eject it, to test is for future ejection and implementation of native APIs, but I get the error "missing script: eject"

@Benzer1406 we're working on adding this functionality to projects created by Expo tools, but aren't there quite yet.

@gnenov89 you run those command in your Terminal / Command Line and paste the outputs in the respective fields.
