Example doesn't work using Rollup CLI

[bertday]

Expected behavior

When I follow the instructions in the example for building via Rollup CLI, I expect it to output a bundle to the dist directory.

Actual behavior

It throws an error:

[!] Error: Cannot find module '../dist/rollup-plugin-vue.common.js'

So, the first thing that's missing is -- the instructions should say you have to cd .. && npm install && npm run build first before running the example.

Then, I got another error:

[!] Error: You must specify options.format, which can be one of 'amd', 'cjs', 'es', 'iife' or 'umd'

There's also a warning:

(!) Some options have been renamed
https://gist.github.com/Rich-Harris/d472c50732dab03efeb37472b08a3f32
--output is now --output.file

So it seems the API has changed since this example was written. Just wanted to give a heads up :)

Steps to reproduce the behavior

Follow the instructions in example/README.md.

Hi has there been a regression? I am still getting [!] Error: Cannot find module '../dist/rollup-plugin-vue.common.js' when I follow the example README.md

Then I did cd .. && npm install && npm run build and then followed the README.md again, this time I got this error (I must be doing something very stupid):

C:\repos\rollup-plugin-vue\example [master ≡ +1 ~3 -0 !]> rollup -c --input Hello.vue
(!) Some options have been renamed
https://gist.github.com/Rich-Harris/d472c50732dab03efeb37472b08a3f32
name is now output.name
format is now output.format

Hello.vue → stdout...
