从 Expo（使用 ExpoKit）弹出后出现此问题。在弹出之前有一个工作环境。npm run ios将一遍又一遍地重复这个问题：

来源：工人（PID 6336）12:18:06：[错误]错误：getaddrinfo ENOTFOUND lcalhost 12:18:06：在 errnoException（dns.js:28:10）12:18:06：在 GetAddrInfoReqWrap.onlookup [as完成] (dns.js:76:26)

Expo XDE 根本不会运行并重复此消息。XCode 包含 C++11 编译器。

错误：µWebSockets 的编译失败，并且没有可用于您的系统的预编译二进制文件。请安装支持的 C++11 编译器并重新安装模块“uws”。

正如@SyedZainAli提到的，这可能是由环境引起的。然后要尝试的几件事是：

  • 删除 node_modules，运行npm cache clean并重新安装
  • 重新安装 NodeJS
  • 使用 CRNA 创建新应用并进行比较

在我的情况下，弹出和使用Expo react-native 分支（默认行为）会导致问题。改回官方的 react-native npm 包解决了这个问题。所以应该是世博会的事情。

我不知道这是否对您有帮助，但它解决了我在 docker 中的问题。

在 Docker 文件中

///////////////////////////////////////// //////////////////////

FROM node:8.9-alpine

RUN apk add --update \ libc6-compat

///////////////////////////////////////// //////////////////////

需要libc6-compact

所以尝试安装libc6-compat.

当我尝试启动从我的 Expo 团队获得的应用程序时，我遇到了同样的问题（如下）。结果发现uws项目中的版本与我使用的 Node 版本不兼容。- 节点 v10.15.0

将节点版本切换为8.11.4使用 nvm -nvm use 8.11.4解决了我的问题。（如果没有安装 8.11.4 版本，请nvm install 8.11.4改用）
