npm run dev 报错

UnhandledPromiseRejectionWarning: Error: getaddrinfo ENOTFOUND localhost
    at GetAddrInfoReqWrap.onlookup [as oncomplete]
(node:5316) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)

这个报错是因为本地没有配host

新增host 127.0.0.1 localhost
