无法使用终端 Visual Studio 在本地服务器上启动谷歌云功能

Question

我正在尝试开发我的第一个 Google Cloud Function，但想在本地构建和测试。我以前没有这样做过，我只是在学习，所以请耐心等待。

首先- 我创建了moralisaccount目录，使用默认配置创建了 package.json npm init，并安装了功能框架npm install @google-cloud/functions-framework

AMAC02CLCBTLEE:moralisaccount youthdev$ nvm use node
Now using node v17.3.0 (npm v8.3.0)
AMAC02CLCBTLEE:moralisaccount youthdev$ npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help init` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.
package name: (moralisaccount) 
version: (1.0.0) 
description: 
entry point: (index.js) 
test command: 
git repository: 
keywords: 
author: 
license: (ISC) 
About to write to /Users/youthdev/MoralisAccount/package.json:

{
  "name": "moralisaccount",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}


Is this OK? (yes) 
AMAC02CLCBTLEE:moralisaccount youthdev$  npm install @google-cloud/functions-framework

added 103 packages, and audited 104 packages in 4s

8 packages are looking for funding
  run `npm fund` for details

found 0 vulnerabilities
AMAC02CLCBTLEE:moralisaccount youthdev$ 

第二- 在与我的 package.json 相同的moralisaccount目录中创建了简单的index.js文件，其中包含一个简单的函数

/**
 * Responds to any HTTP request.
 *
 * @param {!express:Request} req HTTP request context.
 * @param {!express:Response} res HTTP response context.
 */
 exports.moralisAccount = async (req, res) => {
    let message = req.query.message || req.body.message || 'Hello World!';
    res.status(200).send(message);
  };

最后- 我在 Visual Studio 的终端中运行了以下命令，但在终端中没有得到预期的响应。

实际的

Node.js v17.3.0
youthdev@AMAC02CLCBTLEE moralisaccount % node node_modules/@google-cloud/functions-framework --target=moralisAccount
youthdev@AMAC02CLCBTLEE moralisaccount % 

预期的：

Node.js v17.3.0
youthdev@AMAC02CLCBTLEE moralisaccount % node node_modules/@google-cloud/functions-framework --target=moralisAccount


Serving function...
Function: moralisAccount
URL: http://localhost:8080/

由于我是初学者，不确定我在哪一步搞砸了。谢谢你的帮助！

尝试使用下面的链接按照步骤操作，效果很好。

https://github.com/GoogleCloudPlatform/functions-framework-nodejs

在您的场景中，不要运行，而是node node_modules/@google-cloud/functions-framework --target=moralisAccount尝试运行npx @google-cloud/functions-framework --target=moralisAccount

示例输出：

o@cloudshell:~/myapp/routes $ npx @google-cloud/functions-framework --target=helloWorld
Serving function...
Function: helloWorld
Signature type: http
URL: http://localhost:8080/

确保在您的index.js目录中运行该命令。
