第一次使用Nuxt，環境都沒有搭起來，各種報錯。
其中一次提示如下信息：
Error: EPERM: operation not permitted
意思是權限不被允許。我用了幾種方法都不行，目前這種方法有點反應了，便記錄下來。
解決辦法是如下：
1.刪除項目根目錄下的package-lock.json文件（不確定不刪除是否可以）；
2.刪除node_modules文件夾
2.打開終端，運行npm cache clean --force;
3.在終端中執行cnpm install;
第一次執行cnpm install依然有問題，沒看懂什么意思
第二次執行cnpm install貌似問題解決了

然后可以訪問了
訪問如下網址，但我不知道為什么端口號是這個，之前變過好幾次。

第一次使用，貌似搭建成功了，之后再完善
安裝幻燈片插件
同樣遇見了問題，執行了兩邊下面代碼才成功
在執行命令前需要先停止項目
npm install vue-awesome-swiper
