The error "xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools)" typically indicates that the Command Line Tools for Xcode are not correctly installed or configured on your Mac. This can happen after an OS update or if the Command Line Tools were removed.

Here are the steps to fix this issue:

1. Install or Reinstall Command Line Tools

Option A: Using Terminal Command

Open Terminal.

Run the following command to install the Command Line Tools:

xcode-select --install


A pop-up window will appear. Click "Install" to start the installation.

Option B: Manually Download from Apple Developer Website

Go to the Apple Developer Downloads page.

Log in with your Apple ID.

Search for "Command Line Tools for Xcode" and download the latest version.

Open the downloaded .dmg file and follow the installation instructions.

2. Reset Command Line Tools Path

If the above installation does not resolve the issue, you can reset the path:

Open Terminal.

Run the following commands:
sudo xcode-select --reset


This command resets the path to the Command Line Tools.

3. Check and Update Xcode

If you have Xcode installed, ensure it is updated:

Open the App Store.

Check the "Updates" tab for any updates to Xcode.

Install any available updates.

4. Verify Installation

Finally, verify that the Command Line Tools are properly installed and configured:
