npm install失败

重新npm install，还报错，执行下面代码

rm -rf node_modules
rm package-lock.json
npm cache clear --force
npm install

yarn install 提示：

1.更换淘宝镜像：
yarn config set registry https://registry.npm.taobao.org
2.删除代理：
yarn config delete proxy
npm config rm proxy
npm config rm https-proxy
3.安装cnpm设置代理
安装cnpm镜像
npm install -g cnpm --registry=https://registry.npm.taobao.org
使用代理registry
npm config set registry https://registry.npm.taobao.org

如果上述操作后还是报错，则删除yarn.lock文件，重新执行yarn install
