【问题描述】：

我想在我的 nginx 服务器上安装 mechanic。

执行sudo npm install -g mechanic时出现此错误：

tigaron@galaxybrainpower:/var/www/tigaron$ sudo npm install -g mechanic
/usr/bin/mechanic -> /usr/lib/node_modules/mechanic/bin/mechanic

这里发生了什么？如何修复此错误并继续安装？

【解决方案1】：

This answer 解决了我在安装不同软件包时遇到的同样问题。

显然nobody 用户在全局构建包时使用，但目录归root 所有，因此权限失败。答案建议使用以下命令配置npm 以使用root。

npm -g config set user root
