atlas-create-jira-plugin Command Error

[tmcclure4]

Hi everyone. I am new to Atlas and I am following the following tutorial on creating a plugin for Atlas, but I keep getting an error.  https://developer.atlassian.com/docs/getting-started/set-up-the-atlassian-plugin-sdk-and-build-a-project/create-a-helloworld-plugin-project

When I run the command "atlas-create-jira-plugin," the following error occurs.

I've tried looking online for how to fix this, but to no avial. If any other information is needed, let me know. 

Thank you.
