How to Uninstall Expo CLI: A Step-by-Step Guide

Uninstalling Expo CLI is crucial when transitioning to newer tools or resolving conflicts. The Expo CLI package has been deprecated, meaning it no longer receives updates or support. Scenarios where uninstalling might be necessary include upgrading to the latest Expo CLI version, fixing issues caused by outdated dependencies, or switching to a different development setup. This ensures a smoother, more efficient development experience.

Using npm to Uninstall Expo CLI

Here are the steps to uninstall Expo CLI using npm:

1. Open your terminal or command prompt.
2. Type the following command:

   npm uninstall -g expo-cli
   

3. Press Enter.

This command will remove the Expo CLI from your global npm installation.

Using Yarn to Uninstall Expo CLI

To uninstall Expo CLI using Yarn, follow these steps:

1. Open your terminal.
2. Run the command: yarn global remove expo-cli.

This command will remove the Expo CLI from your global Yarn installation.

Verifying the Uninstallation

1. Run expo --version:

   • If Expo CLI is uninstalled, you’ll see a “command not found” error.

2. Run which expo (Linux/macOS) or where expo (Windows):

   • If Expo CLI is uninstalled, no path will be returned.

Additional Cleanup

Sure, here are the steps:

1. Edit package.json:

   • Open your package.json file.
   • Remove any Expo-related dependencies, such as expo, expo-cli, or other related packages.

2. Clear node_modules:

   • Delete the node_modules folder to remove all installed packages.
   • Run npm install or yarn install to reinstall the necessary dependencies without the Expo packages.

3. Uninstall Expo CLI (if installed globally):

   • Run npm uninstall -g expo-cli or yarn global remove expo-cli to remove the Expo CLI from your global environment.

4. Verify Uninstallation:

   • Check if Expo CLI is uninstalled by running expo --version. If it returns “command not found,” the uninstallation was successful.

5. Update React Native CLI:

   • If you plan to use the React Native CLI, ensure it is installed and updated by running npm install -g react-native-cli.

These steps should help you remove Expo-related dependencies from your project effectively.

Uninstalling Expo CLI

To remove Expo CLI from your system, use npm by running npm uninstall -g expo-cli in your terminal, or Yarn with yarn global remove expo-cli.

Next, remove Expo-related dependencies from your package.json file and delete the node_modules folder to clear unnecessary packages.

To verify that Expo CLI has been uninstalled successfully, check for a ‘command not found’ error when running expo --version.

Finally, update React Native CLI if necessary. Maintaining a clean development environment ensures a smoother experience.
