• I confirm that this is a issue rather than a question.

Bug report

Version

vuepress 1.0.0-alpha.25

Steps to reproduce

Reproduction repo: https://github.com/spiltcoffee/vuepress-dev-crash
Note: Requires nodejs v10 or greater to reproduce.

What is expected?

vuepress dev to work

What is actually happening?

vuepress dev crashes.

I think it's related to PR #1051 / commit e570252

In nodejs v10, an underlying library made a change that broke doing things like reading a writable only stream.

This means the following line alone would now cause an error:

process.stdout.on('data', () => {});

The error actually occurs on nodejs v8, but it doesn't close the writable stream like it does on nodejs v10, which is, I'm guessing, why it wasn't noticed.

p.s. sorry for not raising this as an issue earlier, instead insisting on commenting on a closed pull request. My bad!
