How do I create an Expo app when it keeps giving this error? – Ubuntu

Tried every possible step

  • Reinstalled Node, NPM, Expo, etc.
  • Cleaned Cache, verified it aswell.
  • Please help or I would have to reinstall Ubuntu.
faisal@PC:~$ expo init

Migrate to using:
› npx create-expo-app --template

✔ What would you like to name your app? … my-app
✔ Choose a template: › blank               a minimal app as clean as an empty canvas
Error downloading and extracting template package: TypeError: Cannot read properties of null (reading '0')
✖ Something went wrong while downloading and extracting the template.

    Reinstalled Node using NVM

    Apparently the node I installed multiple times through the store was giving the error so I decided to use the Node Version Manager instead.

    Instructions:

    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh

    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

    source ~/.bashrc

    nvm list-remote

    nvm install v16.17.1

    And yes, it works:

    faisal@pc:~$ nvm install v16.17.1
Downloading and installing node v16.17.1...
Downloading https://nodejs.org/dist/v16.17.1/node-v16.17.1-linux-x64.tar.xz...

Migrate to using:
› npx create-expo-app --template

✔ What would you like to name your app? … my-app
✔ Choose a template: › blank               a minimal app as clean as an empty canvas
✔ Downloaded template.
📦 Using npm to install packages.
✔ Installed JavaScript dependencies.

✅ Your project is ready!

To run your project, navigate to the directory and run one of the following npm commands.

- cd my-app
- npm start # you can open iOS, Android, or web from here, or run them directly with the commands below.
- npm run android
- npm run ios # requires an iOS device or macOS for access to an iOS simulator
- npm run web

    If you previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

    Run this command
    npm uninstall -g react-native-cli @react-native-community/cli

    Start a new project
    npx react-native init AwesomeProject
