npm 下载依赖报错npm WARN deprecated core-js@2.6.12: core-js@＜3.4 is no longer maintained and not recommend

从github拉取的项目安装依赖报错，报错信息如下：

1.  
   npm WARN deprecated core-js@2.6.12: core-js@<3.4 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.
2.  
   npm ERR! Cannot read properties of null (reading 'pickAlgorithm')

通过输入 npm outdated后，显示项目package配置信息：

1.  
   Package Current Wanted Latest Location
2.  
   core-js 3.20.1 3.22.8 3.22.8 node_modules/core-js

全局下载core-js,在重新安装依赖 npm install ,查看是否还报错

npm install --save -g core-js@^3

如果还是报错清一下缓存，

npm cache clear --force

再重新安装依赖npm install，安装成功后运行项目 npm run dev
