Webpack dev server won't start with --production

[sergeymorkovkin]

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

Bug report

Steps to reproduce

Use the most primitive Vuepress project, as instructed in guide.

What is expected?

Webpack-dev-server should work with --production flag.

What is actually happening?

Running the vuepress dev ./src command with --production flag fails to start dev-server.

Other relevant information

Running the vuepress dev ./src command doesn't show errors (which is another issue). But there is a cross before the "Client" webpack task. I've debugged and figured out that it's due to webpack output configuration. Following code helps me to bypass this bug:

config.output.filename(isProd() ? 'assets/js/[name].[hash:8].js' : 'assets/js/[name].js');
