SyntaxError:意外的标记'const' – 尽pipe我取代了const

我试图导出我的firebase应用程序,所以我可以称之为摩卡testing规范,以及我试图testing的源代码。

我的摩卡testing规格如下所示:

import Vue from 'vue' import Edit from '@/components/Edit' import filedata from '../../../static/filedata.js' import submitFile from '../../../helpers/submitFile.js' import firebaseapp from '../../../src/db.js' var db = firebaseapp.database() var storage = firebaseapp.storage() describe('Edit.vue', () => { it('should let me add files without choosing a category', () => { // add files to appear on the homepage var Constructor = Vue.extend(Edit) var vm = new Constructor().$mount() console.log(filedata + ' is the file data') var ref = storage.ref('categories') console.log(ref) submitFile(filedata) }) ... 

submitFile文件如下所示:

 var firebaseapp = require('../src/db.js') console.log('the app is: ' + firebaseapp) var db = firebaseapp.database() var storage = firebaseapp.storage() module.exports = function(files){ // is the function being called from the test environment? if(files){ console.log(files) } else { // function called from src -- files were null var files = this.$refs.upload.uploadFiles; } var storageRef = storage.ref(); var pdfsRef = storageRef.child('files'); // var self = this; console.log('the files length is ' + files.length) files.forEach(function(file){ var file = file['raw']; var name = file['name'] var fileref = storageRef.child(name); var uploadTask = fileref.put(file); uploadTask.then(function(snapshot){ console.log('uploaded'); var url = snapshot.downloadURL; self.gettext(url, name); }); try { uploadTask.on('state_changed', function(snapshot){ // Observe state change events such as progress, pause, and resume // Get task progress, including the number of bytes uploaded and the total number of bytes to be uploaded self.uploadProgress = (snapshot.bytesTransferred / snapshot.totalBytes) * 100; console.log(self.uploadProgress + ' is the upload progress.'); switch (snapshot.state) { case app.storage.TaskState.PAUSED: // or 'paused' console.log('Upload is paused'); break; case app.storage.TaskState.RUNNING: // or 'running' console.log('Upload is running'); break; } }, function(error) { // Handle unsuccessful uploads }, function() { // Handle successful uploads on complete // For instance, get the download URL: https://firebasestorage.googleapis.com/... var downloadURL = uploadTask.snapshot.downloadURL; }); } catch(e){ console.log(e) } }) } 

最后,这里是db.js的样子:

 var Firebase = require('firebase')//import Firebase from 'firebase' var config = { ... }; var app = Firebase.initializeApp(config) /// USED TO BE CONST APP export default app 

非常奇怪的是,当我运行npm run unit ,得到一个错误,告诉我const不被识别。

  SyntaxError: Unexpected token 'const' at webpack:///src/db.js~:11:0 <- index.js:38182 

所以我通过我的db.js文件并将const更改为var ,并且我得到完全相同的错误*,不pipe我如何更改文件。

有谁知道会发生什么事?

这是我的package.json
