报TypeError: Cannot read property ‘endsWith‘ of undefined_cannot read property 'endswith' of undefined

在cloen下载vue3项目，npm  i 完成后，npm run serve 报以下错误信息

$ npm run serve

重新npm i 依旧报错，最后想到使用yarn来安装试试。

error @typescript-eslint/eslint-plugin@5.41.0: The engine "node" is incompatible with this module. Expected version "^12.22.0 || ^14.17.0 || >=16.0.0". Got "14.16.1"

还是报错，但是这次的报错就很明确了，node版本不对，必须大于16.0.0

 切换nvm的node版本。从14.16.1改为116.13.2

重新yarn,没有报错

 yarn serve依旧报错

 百度了一下发现endsWidth是js的写法，我就搜有没有例外的写法，果然黄天不负苦心人，搜到了  'abcdef'.split("f").slice(-1)[0] === ""   这种判断方法

"被查询字符串".split("结尾字符串").slice(-1)[0] === ""
 
例如：
'abcdef'.split("g").slice(-1)[0] === "";//false
'abcdef'.split("abcde").slice(-1)[0] === "";//false
'abcdef'.split("f").slice(-1)[0] === "";//true
'abcdef'.split("def").slice(-1)[0] === "";//true
 
例如判断格式exe
"文.件.名.exe".split('.').slice(-1)[0] === "exe"//true
"文.exe.件.名".split('.').slice(-1)[0] === "exe"//false
"文.件.名exe.".split('.').slice(-1)[0] === "exe"//false
"文件名.exe.abc.exe.abc".split('.').slice(-1)[0] === "exe"//false

但是还在报错，我就猜测不是方法的问题，是前面值的问题，增加了一个 '?'  就不报错了。

欧克了，兄弟们，曲折啊，前进的道路上几多崎岖啊。
