   The active developer path is a directory that contains the developer tools, such as xcodebuild and xcrun. In order to use the tools, you must set the path to the directory that contains them.

If you receive the error message “xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools),” this means that the directory that contains the developer tools is not in your path. To fix this, you must add the directory to your path.

There are two ways to do this:

1. Use the “export” command to add the directory to your path. This method will only work for the current session. To make the change permanent, you must add the “export” command to your shell configuration file (such as ~/.bash_profile).
2. Use the “sudo xcode-select -switch” command to change your active developer directory. This method will make the change permanent.
