Hot reload doesn't normal work without --temp .temp

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

Bug report

If you do not set --temp .temp, hot reload can only reload markdown, but can not reload config.js files, navigation bar, sidebar title, front matter, etc.

Version

Steps to reproduce

1. npm install -g vuepress@next
2. echo '# Hello VuePress!' > README.md
3. Create file .vuepress/config.js

module.exports = {
  themeConfig: {
    nav: [
      { text: 'home', link: '/' }
    ],
    sidebarDepth: 2,
    sidebar: {
      '/': [
        ['', 'home']
      ]
    }
  }
}

1. vuepress dev .
2. Edit file .vuepress/config.js

module.exports = {
  themeConfig: {
    nav: [
      { text: 'home', link: '/' }
    ],
    sidebarDepth: 2,
    sidebar: {
      '/': [
        ['', 'newHome']
      ]
    }
  }
}

What is expected?

sidebar title 'home to newHome

What is actually happening?

no change

@Xinyii 非常感谢你提供的帮助 ：vuepress dev . --temp .temp，它确实可行。 在这之前，我在官方文档中找不到这行命令的说明，我被sidebar无法自动更新的问题困扰了很久。

在0.x的版本中，sidebar自动更新是可以正常工作的。 但是当我切换到1.x版本之后，sidebar就无法自动更新了

我特地制作了一个Gif图，希望它对你们有帮助。

Since you’re using a globally installed vuepress, the temp files will be placed under the global installed directory so that VuePress cannot detect the change of it.
