bundler and theme are required while init a vuepress project through npm

[Jaylee89]

Follow this guide to init a vuepress project through npm, but get error bundler and theme are required, why?

"vuepress": "^2.0.0-beta.41"

https://v2.vuepress.vuejs.org/zh/guide/getting-started.html#%E6%89%8B%E5%8A%A8%E5%AE%89%E8%A3%85

You need to set bundler and theme now. @meteorlxy Docs may need an update.

Edited: https://stackblitz.com/fork/vuepress-8ur7dq the demo is working for me. If you have any troubles, a same minimal reproduction repo is required.
