Google Firebase Web App - 涉及云功能和Firestore的错误

Question

最近,我尝试在线跟踪一些演示,开始使用Google Firebase Cloud Functions Node.js服务器端代码.在尝试添加Firebase应用程序(以及带有它的Firestore)时,

const functions = require('firebase-functions');
const firebase = require('firebase-admin');
require('firebase/firestore');

var serviceAccount = require("<private key>.json");

const initAppFirebase = firebase.initializeApp({
    credential: firebase.credential.cert(serviceAccount),
    databaseURL: "<URL>"
});

var db = firebase.firestore();

我开始得到这一个错误,它提到了google-gax模块中丢失的"annotations.proto"文件(显然是在Firestore中的某个点导入的).

Error during trigger parsing:  Error occurred while parsing your function 
triggers.
Error: The include `google\api\annotations.proto` was not found.
    at Function.GoogleProtoFilesRoot._findIncludePath 
(C:\...\functions\node_modules\google-gax\lib\grpc.js:312:11)
    at GoogleProtoFilesRoot.resolvePath 
(C:\...\functions\node_modules\google-gax\lib\grpc.js:298:31)
...
    at v1beta1 (C:\...\functions\node_modules\@google- 
cloud\firestore\src\v1beta1\index.js:30:10)
    at new Firestore (C:\...\functions\node_modules\@google- 
cloud\firestore\src\index.js:229:18)

我在互联网上环顾四周,但似乎没有其他人有这个问题.我刚刚重新安装了这些文件,但我仍然遇到了这个问题.删除Firestore和Firebase initializeApp代码可以使其正常工作,因此我认为它与此有关.

这是我的模块版本 package.json

"firebase-admin": "^5.12.0",
"firebase-functions": "^1.0.1",
"firestore": "^1.1.6",

有没有办法解决这个问题(拙劣的安装,过时的库,缺少代码/要求等)？非常感谢你.

编辑:添加代码和package.json版本信息.我在实际文件中挖掘 \node_modules\google-gax\lib\grpc.js并发现它试图annotation.proto通过尝试google\api\annotations.proto在每个父目录中测试来返回导致导入文件的有效路径.

var current = originPath;
var found = fs.existsSync(path.join(current, includePath));
while (!found && current.length > 0) {
  current = current.substring(0, current.lastIndexOf(path.sep));
  found = fs.existsSync(path.join(current, includePath));
}
if (!found) {
  throw new Error('The include `' + includePath + '` was not found.');
}
return path.join(current, includePath);

遗憾的是,没有这样的目录,但可能正在寻找注释文件google-proto-files\google\api\annotations.proto(但手动添加该文件会导致进一步的错误).这里还有一个github问题https://github.com/googleapis/nodejs-firestore/issues/175提到它.

Answer 1

你说你正在尝试构建一个Web应用程序.但您使用的代码是在(服务器端)Node.js脚本中初始化Firebase Admin SDK.

如果要在Web应用程序中使用Firestore,请从单击此页面WEB上的选项卡时看到的代码开头:

<script src="https://www.gstatic.com/firebasejs/4.12.0/firebase.js"></script>
<script src="https://www.gstatic.com/firebasejs/4.12.0/firebase-firestore.js"></script>

然后:

firebase.initializeApp({
  apiKey: '### FIREBASE API KEY ###',
  authDomain: '### FIREBASE AUTH DOMAIN ###',
  projectId: '### CLOUD FIRESTORE PROJECT ID ###'
});

// Initialize Cloud Firestore through Firebase
var db = firebase.firestore();

您可以通过以下方式获取该initializeApp调用中的值:

1. 去Project overview页面
2. 点击 ADD ANOTHER APP
3. 点击 Add Firebase to your web app
