嘗試建立我的 vuepress 專案時出錯，使用 npm 快速入門指南： https://vuepress.vuejs.org/guide/getting-started.html#manual-installation
我新增了一些頁面，一切正常：
npm run:dev
但是當我想要產生 html 到 docs/src/.vuepress 時：
npm run:build
dibTest@0.0.1 build
vuepress build src

這個錯誤是由我的 config.js 中的以下問題引發的
module.exports = { ... sidebar: [ '/', { title: 'Quick Start Guide', children: [ '/overview/login.md', '/overview/model-list.md', '/overview/navigation.md,' ] } ] } }注意「navigation.md」後面的「,」。無論出於何種原因，這都會導致上述完全無用的消息。一定是因為它找不到該 md 文件，然後它在某處獲取未定義並嘗試訪問它，而不是檢測到它並給您有用的消息
