Firebase-节点云功能错误解析触发器：找不到模块“ firebase-functions”

标签： node.js firebase google-cloud-functions node-modules

在尝试部署时，我一直遇到这个问题。最初，只有启动器“ hello，world”云功能可以在Firebase上部署。

我已经安装了Node 8，我意识到这可能是我的问题。我进行了搜索，发现只要指定引擎即可，例如：

package.json代码段

 "engines": {
    "node": "8"
  },

但是添加完后我得到了相同的结果。

这是我完整的package.json 

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "serve": "firebase serve --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "dependencies": {
    "@google-cloud/storage": "^2.0.3",
    "busboy": "^0.2.14",
    "cors": "^2.8.4",
    "firebase-admin": "^6.0.0",
    "firebase-functions": "^2.0.5",
    "request-promise": "^4.2.2",
    "uuid": "^3.3.2"
  },
  "engines": {
    "node": "8"
  },
  "private": true
}

这是我的functions文件夹中的index.js 

'use strict';
// // Create and Deploy Your First Cloud Functions

});

exports.storeImage = functions.https.onRequest((req, res) => {
  return cors(req, res, () => {
    if (req.method !== 'POST') {
      return res.status(500).json({ message: 'Not allowed.' });
    }

    if (
      !req.headers.authorization ||
      !req.headers.authorization.startsWith('Bearer ')
    ) {
      return res.status(401).json({ error: 'Unauthorized.' });
    }

    let idToken;
    idToken = req.headers.authorization.split('Bearer ')[1];

    const busboy = new Busboy({ headers: req.headers });
    let uploadData;
    let oldImagePath;

    busboy.on('file', (fieldname, file, filename, encoding, mimetype) => {
      const filePath = path.join(os.tmpdir(), filename);
      uploadData = { filePath: filePath, type: mimetype, name: filename };
      file.pipe(fs.createWriteStream(filePath));
    });

    busboy.on('field', (fieldname, value) => {
      oldImagePath = decodeURIComponent(value);
    });

    busboy.on('finish', () => {
      const bucket = gcs.bucket('rs-0001.appspot.com');
      const id = uuid();
      let imagePath = 'images/' + id + '-' + uploadData.name;
      if (oldImagePath) {
        imagePath = oldImagePath;
      }

      return fbAdmin
        .auth()
        .verifyIdToken(idToken)
        .then(decodedToken => {
          return bucket.upload(uploadData.filePath, {
            uploadType: 'media',
            destination: imagePath,
            metadata: {
              metadata: {
                contentType: uploadData.type,
                firebaseStorageDownloadTokens: id
              }
            }
          });
        })
        .then(() => {
          return res.status(201).json({
            imageUrl:
              'https://firebasestorage.googleapis.com/v0/b/' +
              bucket.name +
              '/o/' +
              encodeURIComponent(imagePath) +
              '?alt=media&token=' +
              id,
            imagePath: imagePath
          });

          return null
        })
        .catch(error => {
          return res.status(401).json({ error: 'Unauthorized!' });
        });
    });
    return busboy.end(req.rawBody);
  });
});

对于类似的问题，我已经使用了先前的建议，建议先转到/ functions /目录并进行 npm安装，然后继续转到上一个目录并运行

firebase deploy --only functions

这使我回到

i  functions: preparing functions directory for uploading...

Error: Error parsing triggers: Cannot find module 'firebase-functions'

Try running "npm install" in your functions directory before deploying.

我已经在--debug上运行它，以接收

i  functions: preparing functions directory for uploading...

我什至尝试过

 cd functions && sudo npm i && cd .. && firebase deploy --only functions --debug

得到相同的结果。我似乎花了几个小时来解决相​​同的问题，删除了node_modules，单独安装了所有软件包，等等。有人可以帮忙吗？ 

node -v

v8.12.0 

npm -v

6.4.1

我以最新版本全局安装了firebase-tools，并将项目的.json放在同一目录中...

尝试一下。

  1. 使用任一方法在本地运行此代码

    • firebase functions:shell或
    • firebase serve --only functions

    有关更多详细信息，请参见this。

  2. 在将在您的目录中生成的 firebase-debug.log 文件中查找详细的堆栈跟踪。

有一个不兼容的软件包。

    "@google-cloud/storage": "^2.0.3",

需要

    "@google-cloud/storage": "^1.7.0",

由于某种原因，之后我就可以上传了。这是我的functions / index.js的工作版本

    'use strict';

const functions = require('firebase-functions');
const cors = require('cors')({origin: true});
const Busboy = require('busboy');
const os = require('os');
const path = require('path');

const uuid = require('uuid/v4');
// // Create and Deploy Your First Cloud Functions

//
// exports.helloWorld = functions.https.onRequest((request, response) => {
//  response.send("Hello from Firebase!");
// });
const gcconfig = {
    projectId: 'rs-0001',
    keyFilename: 'rs-0001.json'
};

const gcs = require('@google-cloud/storage')(gcconfig);

fbAdmin.initializeApp({credential: fbAdmin.credential.cert(require('./rs-0001.json'))})

exports.storeImage = functions.https.onRequest((request, response) => {
    return cors(req, res, () => {
        if (req.method !== 'POST') {
            return res.status(500).json({message: 'Not allowed mofo.' });
        }
    if (!req.headers.authorization ||
        !req.headers.authorization.startsWith('Bearer ')
        ) { 
        return res.status(401).json({ error: 'Unauthorized '});
    }

    let idToken;
    idToken = req.headers.authorization.split('Bearer ')[1];

    const busboy = new Busboy({headers: req.headers});
    let uploadData;

    busboy.on('file', (fieldname, file, filename, encoding, mimetype) => {
        const filePath = path.join(os.tmpdir(), filename);
        uploadData = {filePath: filePath, type: mimetype, name: filename};
        file.pipe(fs.createWriteStream(filePath));
    });

    busboy.on('field', (fieldname, value) => {
        oldImagePath = decodeURIComponent(value);
    })

    busboy.on('finish', () => {
        const bucket = gcs.bucket('rs-0001.appspot.com');
        const id = uuid();
        let imagePath = 'images/' + id + '-' + uploadData.name
        if (oldImagePath) {
            imagePath = oldImagePath;

        }

        return fbAdmin
        .auth()
        .verufyIdToken(idToken)
        .then(decodedToken => {
            return bucket.upload(uploadData.filePath, {
                uploadType: 'media',
                destination: imagePath,
                metadata: {
                    metadata: {
                        contentType: uploadData.type,
                        firebaseStorageDownloadToken: id
                    }
                }
            });
        })
        .then(() => {
            return res.status(201).json({
                imageUrl: 
                    'https://firebasestorage.googleapis.com/v0/b/' + 
                    bucket.name + 
                    '/o/' + 
                    encodeURIComponent(imagePath) + 
                    '?alt=media&token' + 
                    id,
                imagePath: imagePath
            });
        })
        .catch(error => {
            return res.status(401).json({ error: 'Unauthorized!' });
        });
    });
    return busboy.end(req.rawBody);
    });
});

这是我的完整package.json，

非常感谢您的回答。我希望我的解决方案可以帮助某人
