To resolve this issue, you need to ensure that the docker-sync command gets installed in a directory that's included in your system's PATH. Here’s how to do it step-by-step:

Step 1: Use the Correct Install Command

This command does the following:

--user-install: Installs the gem for the current user, avoiding permission issues that can arise from using sudo.

-n /usr/local/bin: Specifies the output directory for the command, ensuring it's in a common executable directory.

Step 2: Verify the Installation

After running the installation command, you need to verify that it was successful and that you can access docker-sync. You can do this by checking its version again:
