云功能不下载依赖项

Question

我试图在Google函数上部署一个Node.js应用程序，但它似乎没有下载我的任何依赖项。每当我的代码碰到require行时，它都会抛出以下错误：

Deployment failure:
Function load error: Code in file app.js can't be loaded.
Did you list all required modules in the package.json dependencies?
Detailed stack trace: Error: Cannot find module 'googleapis'
    at Function.Module._resolveFilename (module.js:469:15)
    at Function.Module._load (module.js:417:25)
    at Module.require (module.js:497:17)
    at require (internal/module.js:20:19)
    at Object.<anonymous> (/user_code/app.js:1:63)
    at Module._compile (module.js:570:32)
    at Object.Module._extensions..js (module.js:579:10)
    at Module.load (module.js:487:32)
    at tryModuleLoad (module.js:446:12)
    at Function.Module._load (module.js:438:3)

我的package.json依赖项块：

  "dependencies": {
    "actions-on-google": "^1.0.9",
    "body-parser": "^1.15.2",
    "chai-as-promised": "^6.0.0",
    "express": "^4.14.0",
    "express-healthcheck": "^0.1.0",
    "googleapis": "^19.0.0",
    "https": "^1.0.0",
    "istanbul": "^0.4.5",
    "newrelic": "^1.40.0",
    "nodemailer": "^4.0.1",
    "querystring": "^0.2.0",
    "request": "^2.81.0",
    "string-format": "^0.5.0",
    "universal-analytics": "^0.4.13",
    "xml2js": "^0.4.17"
  },

有没有强制安装的方法，或者我这样做有什么问题吗？通过命令functions在本地运行functions deploy runApp --trigger-http包没有错误，并且可以通过本地计算机执行任何我想做的事情。只有尝试在云中设置错误时才会发生错误。

我还尝试通过gcloud beta functions CLI使用--verbose标志(如this answer中提到的)，并获得了以下跟踪：

Answer 1

通过简单地删除"express-healthcheck": "^0.1.0"，我设法让它正常工作。我不知道为什么会导致它崩溃，但是由于它是云函数，我实际上不需要任何与Express相关的东西，所以删除对于我的用例来说不是一个问题。

如果有人知道这会导致错误，请在这里发帖，我很好奇。
