Troubleshooting: “dart pub global activate flutterfire_cli” Command Prompt Issue in Flutter

by

This article addresses the common problem where the command dart pub global activate flutterfire_cli in Windows using Android Studio opens and closes the command prompt immediately.

Understanding the Problem

The issue stems from the command prompt window closing rapidly after executing the command. This typically indicates a problem with the execution process, potentially related to permissions, environment variables, or other factors interfering with the Flutterfire CLI installation.

Possible Causes and Solutions

  • Insufficient permissions: The command might require elevated privileges to modify global packages. Try running the command prompt as administrator.
  • Path environment variable issues: Ensure that the Flutter SDK path is correctly configured in your system’s environment variables. Incorrect paths can lead to unexpected behavior and the prompt closing prematurely.
  • Background processes or conflicts: Sometimes background processes or other applications might interfere with the command execution. Temporarily close any potentially conflicting programs before running the command.
  • Corrupted or outdated packages: There’s a possibility that outdated or corrupted packages are causing issues. Try upgrading Flutter and/or packages and running the command again.
  • Command Prompt Limitations: In rare cases, issues with the command prompt itself can arise. Consider using a different terminal application such as Git Bash or PowerShell.

Detailed Solution Steps

1. Run Command Prompt as Administrator

Right-click on the command prompt icon and select “Run as administrator.”

2. Verify Flutter SDK Path

  1. Open your system’s environment variables settings.
  2. Add or modify the PATH environment variable to include the Flutter SDK path. You will need to locate the directory where your Flutter SDK is installed. This should usually be within a Flutter SDK installation directory. 
    
set PATH=%PATH%;C:\flutter\bin

    Replace C:\flutter\bin with the actual path to your Flutter SDK’s bin directory.

3. Check for Conflicts and Background Processes

Close any potentially interfering applications running in the background before running the command.

4. Updating Flutter and Packages

Ensure you have the latest version of Flutter and its packages. Use the following commands in the command prompt:


flutter upgrade
flutter pub upgrade

5. Try a Different Terminal (Optional)

If the above steps fail, consider using a different terminal application. For example, use Git Bash. This can sometimes resolve command prompt-specific issues.
