第一次使用Nuxt，环境都没有搭起来，各种报错。
其中一次提示如下信息：
Error: EPERM: operation not permitted
意思是权限不被允许。我用了几种方法都不行，目前这种方法有点反应了，便记录下来。
解决办法是如下：
1.删除项目根目录下的package-lock.json文件（不确定不删除是否可以）；
2.删除node_modules文件夹
2.打开终端，运行npm cache clean --force;
3.在终端中执行cnpm install;
第一次执行cnpm install依然有问题，没看懂什么意思
第二次执行cnpm install貌似问题解决了

紧接着我又执行了启动命令

然后可以访问了
访问如下网址，但我不知道为什么端口号是这个，之前变过好几次。

第一次使用，貌似搭建成功了，之后再完善
安装幻灯片插件
同样遇见了问题，执行了两边下面代码才成功
在执行命令前需要先停止项目
npm install vue-awesome-swiper
如图：
