Getting the following error while executing expo init command

Question

Installing dependencies...
npm WARN deprecated core-js@1.2.7: core-js@<2.6.5 is no longer maintained. Please, upgrade to core-js@3 or at least to actual version o         


        

Answer 1

It appears to be a core-js version issue.

In package.json, check "expo-core": "version" and if it is lower than the error:You correct the version to fit the error.

and rm -rf node_modules && npm install

or

npm install -g expo-cli

Once you've done it, try running a new expo init.

Answer 2

The default expo-template-blank template points react-native to their own Github repo - installing from a Github repo might cause the NPM to hang or err out for various reasons.

To work around this ctrl-c to interrupt initialization when it proceeds to install the dependencies after the project scaffolding is done, edit the package.json to install react-native from the NPM registry - for example this is how my dependencies look:

 "dependencies": {
    "expo": "^35.0.1",
    "react": "^16.8.3",
    "react-dom": "^16.8.3",
    "react-native": "^0.59.10"
//...

Then manually do npm i to install the dependencies and enjoy.

Answer 3

This shows when you dont have git installed. You can follow any of the answers above to get it working on local. But if you're facing this issue in deploying a node app, check the node image you're using for deployment. If it is node: alpine then u will get this error.

To fix it, you can use node:carbon image.

Just check that you've git installed on your system. otherwise, download it

Install git from here - https://git-scm.com/downloads

Your problem will be solved cheers! :)

Answer 5

Please make sure, that you have git installed. NPM requires git for installing some of the packages. You can check if git is installed via:

git --version

If so, according to the reported issue, removing and reinstalling node_modules should help:

rm -rf node_modules && npm install

You can also try to resolve the issue with yarn:

brew install yarn
npm uninstall -g create-react-native-app
yarn global add create-react-native-app
