問題描述

當運行 mmdc 命令時，產生以下錯誤：

# mmdc -i demo.mmd -o demo.png
/usr/lib/node_modules/@mermaid-js/mermaid-cli/node_modules/puppeteer/lib/cjs/pup
peteer/node/BrowserRunner.js:193

問題緣由

解決方法

第一步、建立 puppeteer-config.json 文件：

{
  "args": ["--no-sandbox"]
}

第二步、使用該配置文件運行：

mmdc -p puppeteer-config.json ...
