情况：

• 在 Nest 和 grapqhql 中开发 api
• 在一台笔记本电脑上工作，一切正常
• 然后在其他笔记本电脑上克隆我的存储库，安装依赖项，创建一个新的本地数据库。
• 应用程序正在构建，没有错误
• 当在浏览器中关注 localhost:4000 打开 graphql Playground 时，我收到 500 错误结束下一条消息：

捕获错误的护照库函数的代码：

return function authenticate(req, res, next) {
    req.login =
    req.logIn = req.logIn || IncomingMessageExt.logIn;
    req.logout =
    req.logOut = req.logOut || IncomingMessageExt.logOut;
    req.isAuthenticated …

我一直在开发一个连接到本地 Postgres 数据库的 NestJS-GraphQL 应用程序。一切都工作正常，直到 Ubuntu 20.04 重新安装。

在使用项目克隆存储库、安装 Postgres 并使用yarn start:dev构建应用程序后，我可以看到这个奇怪的错误：

[Nest] 21577  - 02/05/2022, 2:51:10 PM   ERROR [TypeOrmModule] Unable to connect to the database. Retrying (1)...
Error: getaddrinfo EAI_AGAIN postgres
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:71:26)

Postgres 正在运行：

hleb@hleb:~$ psql artwine postgres
psql (14.1 (Ubuntu 14.1-2.pgdg20.04+1))
Type "help" for help.
