feat: add envinfo package via vue info in cli

[tabrindle]

As with many other projects, an astounding number of issues and conversations center around what versions of tools, CLIs and OSs users are running. I'd like to help this issue. We already ask for this info, why not automate it?

Other command line tools such as

• React Native
• Create React App
• Expo
• Webpack
• Solidarity
• Gatsby

have all benefitted from adding envinfo to their CLI and issue template.

Here's an example output, custom tailored for Vue:

Next steps would be adding this as a requirement to your issue template, and creating an envinfo preset for vue, so that it can be run without anything installed but node via npx:

npx envinfo --preset vue
