For Vue CLI v3, you can use vue create or vue ui to bootstrap an app. For Vue CLI v2, you use vue init.
If you have Vue CLI v3 installed, you can still use vue init, though it's considered a legacy API:
$ vue --version
3.0.0
$ vue init
Usage: init [options] <template> <app-name>
generate a project from a remote template (legacy API, requires @vue/cli-init)
Options:
-c, --clone Use git clone when fetching remote template
--offline Use cached template
-h, --help output usage information
$ vue create
Usage: create [options] <app-name>
create a new project powered by vue-cli-service
Options:
-p, --preset <presetName> Skip prompts and use saved or remote preset
-d, --default Skip prompts and use default preset
-i, --inlinePreset <json> Skip prompts and use inline JSON string as preset
-m, --packageManager <command> Use specified npm client when installing dependencies
-r, --registry <url> Use specified npm registry when installing dependencies (only for npm)
-g, --git [message] Force git initialization with initial commit message
-n, --no-git Skip git initialization
-f, --force Overwrite target directory if it exists
-c, --clone Use git clone when fetching remote preset
-x, --proxy Use specified proxy when creating project
-b, --bare Scaffold project without beginner instructions
-h, --help output usage information
Vue CLI is stable at version 3, so I would make sure you have that installed, and use the vue create command or the vue ui command. The vue ui is still in beta and I have not yet tried it, but it looks nice. You can go through the CLI website for more information: https://cli.vuejs.org/.
