# 2021-01-09 #「Mermaid」- Running as root without --no-sandbox is not supported

问题描述

当运行 mmdc 命令时，产生如下错误：

# 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

问题原因

因为没有什么研究，所以原因我们也并不清楚（这各问题可是经常出现的）。

解决方法

第一步、创建 puppeteer-config.json 文件：

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

第二步、使用该配置文件运行：

mmdc -p puppeteer-config.json ...
