错误：解析触发器时出错：无法找到模块＆＃39; firebase-fuctions＆＃39;

Question

我想部署Firebase功能，但是当我通过命令firebase部署时，它会显示此错误

  

错误：解析触发器时出错：无法找到模块＆＃39; firebase-fuctions＆＃39;   尝试运行＆＃34; npm install＆＃34;在你的函数目录之前   展开。

我安装了npm安装包，但不能为我工作。我在package.json中更改了依赖项，但对我来说没有用。请帮帮我

节点版本v8.9.3

npm version v5.5.1

firebase版本3.17.6
