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

by

This article addresses the problem of the command prompt closing immediately after running the command “dart pub global activate flutterfire_cli” in Android Studio on a Windows machine.

Problem Description

Users report that when they execute the command “dart pub global activate flutterfire_cli” in their Windows command prompt (often within Android Studio), the prompt opens briefly and then closes without any error message.

Possible Causes and Solutions

Several factors can contribute to this issue, and several troubleshooting steps are provided below.

1. Insufficient Command Prompt Permissions

Problem: The command prompt window might be closing due to insufficient permissions for the executing user to perform the action in the prompt.

Solution: Run the command prompt as administrator. Right-click the command prompt icon and select “Run as administrator”. This will typically grant elevated privileges needed to successfully execute the command.

2. Command Prompt Buffering or Timing Issues

Problem: The command might complete its action so quickly that the command prompt closes without your noticing. FlutterFire CLI installation might be fast, and the prompt is closing after completion before you see the confirmation.

Solution: Try adding a delay or a way to pause the execution of the command within the command prompt. You might try the following:

  • Include a pause command (pause) at the end of the command line. This will keep the command prompt window open until you press a key.
dart pub global activate flutterfire_cli & pause

3. Incompatible Environment Variables

Problem: Certain environment variables might be causing conflict or incompatibility, affecting the execution of the command.

Solution: Verify that your environment variables are correctly set for Flutter and Dart. You can do this in the Windows System Properties.

4. Missing or Corrupted Dart SDK

Problem: An outdated or corrupted Dart SDK could affect the execution.

Solution: Ensure that you have the latest stable Dart SDK version installed and configured correctly. Verify your Flutter installation by running `flutter doctor` in the terminal. Carefully follow the troubleshooting steps in the output for any issues, including checking SDK path.

5. Firewall or Antivirus Interference

Problem: Security software might be blocking the necessary operations.

Solution: Temporarily disable your firewall and antivirus software to rule out interference. If the issue resolves, configure your security settings to allow access for Flutter and Dart installation operations.

Potential Error Messages

While the prompt closes without an error message, sometimes, if there’s a more fundamental problem, you might see an error message in the command prompt window before it closes.

  • “Error: …”: Any error messages should be captured and provide further diagnostic information. Look for specific error messages, such as incorrect paths or permissions.
  • “HTTP Error:…” or network errors: Network issues could impede the installation process. Ensure a stable internet connection and appropriate network permissions for the command execution.

Troubleshooting Steps Summary

  1. Run command prompt as administrator.
  2. Add a pause command at the end of your command.
  3. Verify environment variables for Flutter and Dart.
  4. Ensure Dart SDK is correctly installed and updated.
  5. Temporarily disable firewall/antivirus.

If you continue to experience problems after trying these solutions, please provide more details about your setup, including the Flutter SDK version and any specific error messages you see (even if the prompt closes quickly).
