如何在Google Cloud Functions上安装npm软件包?

问题描述：

我正在尝试创建一个简单的函数，该函数:

I'm trying to create a simple function that:

从公共网址获取JSON文件
进行一些运算，然后给出答案.

我认为Google Cloud Functions非常适合，因为我可以用JS编写代码，而不必担心服务器部署等问题.

I figured that Google Cloud Functions would be the perfect fit since I can code in JS and don`t have to worry about server deployment, etc.

我从没真正使用过nodejs/npm，所以也许是问题所在，但是我尝试在线阅读，他们只是提到

I've never really used nodejs/npm so maybe this is the issue, but I tried reading online and they just mention

npm install package-name

我不确定在"Google云功能"页面上的哪里可以执行此操作.

I'm not sure where I can do this on the Google Cloud Functions page.

我当前正在使用嵌入式编辑器，并且具有以下内容:

I'm currently using the inline editor and I have the following:

var fetch = require('node-fetch');

exports.test2 = (req, res) => {
  fetch("myURLgoes here").then(function(response){
        res.status(200).send('Success:'+response);
    });

我收到以下错误:

错误:函数崩溃了.详细信息: 提取未定义

Error: function crashed.Details: fetch is not defined

答

从Google Cloud Platform控制台转到您的云功能.

From Google Cloud Platform console, go to your cloud functions.

创建或编辑函数时，应该有两个文件: -index.js:您在其中定义函数的位置 -package.json:您在其中定义依赖项的地方.

You should have two files when creating or editing a functions: - index.js: where you define your functions - package.json: where you define your dependency.

开始时您的package.json是这样的:

Your package.json at the start is something like this:

{
  "name": "sample-http",
  "version": "0.0.1"
}

使用以下命令npm install在package.json中添加所有要安装的模块:

Add in your package.json all your module that you'd like to install with the command npm install as below:

{
  "name": "sample-http",
  "version": "0.0.1",
  "dependencies": {
    "@material-ui/core": "^4.1.1"
  }
}

您可以在www.npmjs.com上找到该软件包的最新版本

you can find the last version of the package on www.npmjs.com
