Я делаю проект разработки в vuejs.
Я получаю сообщение в своем консольном браузере: ошибка типа: «экспорт» доступен только для чтения vuejs. Появляется, когда я добавил vue -loader в свой проект. Если я удаляю, у меня появляется ошибка, и я должен установить vue -loader.
Здесь мой webpack.base:
'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
function resolve (dir) {
return path.join(__dirname, '..', dir)
}
module.exports = {
context: path.resolve(__dirname, '../'),
entry: {
app: './src/main.js'
},
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production'
? config.build.assetsPublicPath
: config.dev.assetsPublicPath
},

Как решить эту проблему?
