Nuxt.js vue init nuxt-community/koa-template 初始化项目报错

报错提示：

Module build failed: Error: Plugin/Preset files are not allowed to export objects, only functions. In G:\project\vue\nuxt-learn\node_modules\backpack-core\babel.js

问题原因：backpack-core模块版本低。

解决：更新backpack-core

npm install --save-dev backpack-core@0.7.0

安装警告：

npm WARN uglifyjs-webpack-plugin@0.4.6 requires a peer of webpack@^1.9 || ^2 || ^2.1.0-beta || ^2.2.0-rc || ^3.0.0 but none is installed. You must install peer dependencies yourself.

更新插件：

npm view uglifyjs-webpack-plugin versions

npm i -D uglifyjs-webpack-plugin@2.2.0

运行项目：

npm run dev

报错：

Module build failed (from ./node_modules/eslint-loader/index.js):
TypeError: Cannot read property 'eslint' of undefined
at Object.module.exports (G:\project\vue\nuxt-learn\node_modules\eslint-loader\index.js:148:18)

解决：根目录下nuxt.config.js 更改 ctx.isClient 为 ctx.Client
