[galaxy-dev] ERROR: PIP is not a legl parament of an Ansible Play

Hi, all, Sorry to bother you again. I am trying to install tools using the script. I have downloaded the playbook, but stuck here: [galaxy@Pegasus ansible-galaxy-tools]$ ansible-playbook tasks/tools.yml -i "localhost," --extra-vars galaxy_tools_api_key=xcd2Glx ERROR: pip is not a legal parameter of an Ansible Play I did not find anything related on the Galaxy search either. Any help will be appreciated. The web Admin interface only allows tool installation one by one. I wish it allows batch installation there. Thanks, Bill
