How to Fix the zsh: command not found: adb Error After Configuring PATH Variables for Android SDK

Are you encountering the frustrating zsh: command not found: adb error while trying to run Android Debug Bridge (adb) for your React Native app? You’re not alone. Many users encounter this issue when they add their Android SDK paths to their .zshrc file but still can't access adb command in the terminal. Let’s take a detailed look at the problem and explore effective solutions to get you back on track.

Understanding the Problem

When you see the error message zsh: command not found: adb, it means that your terminal shell (zsh) cannot find the adb command in the directories listed in the PATH variable. This usually happens even if you added the correct paths because of how the .zshrc file is configured or how adb is referenced in your system.

The Setup

You mentioned that you added the following lines to your .zshrc file:

After updating .zshrc and reloading it with source ~/.zshrc, running adb still results in an error.

Why This Happens

Path Configuration:

The paths you added might not be correctly pointing to the actual SDK directory.

On Windows systems, sometimes executable extensions like .exe must be specified, which can complicate access.

Location of SDK:

The Android SDK might be located in a different directory, and your current paths might not match.

Permissions:

It’s also possible that there might be permission issues preventing access to the adb executable.

Approaches to Solve the Issue

To get adb working correctly, you have a few options to consider:

1. Create a Symlink

This is a convenient way to make the adb command work without having to specify the .exe extension:

This command creates a symbolic link, allowing you to run adb seamlessly.

2. Create an Alias

You can define an alias in your .zshrc, which allows you to run adb.exe using a shorter command:

After adding this line, don't forget to reload your .zshrc file:

3. Define a Shell Function

Alternatively, you can define a shell function in your .zshrc to automatically append the .exe when you call adb:

This function takes any arguments you pass to the adb command and forwards them to adb.exe.

Conclusion

By using one of these methods, you should be able to resolve the zsh: command not found: adb error effectively. Whether it’s through creating a symlink, setting an alias, or defining a shell function, these solutions make working with the Android SDK more convenient and user-friendly.

Don’t forget to check your SDK installation directory and confirm all paths in your .zshrc are correct. With these fixes, you'll be back to developing your React Native apps without further issues.
With this guide, you should have everything you need to troubleshoot the adb command error. Happy coding!
