运行“expo start”时显示错误消息（错误：UnhandledPromiseRejectionWarning）

Question

我刚刚将我的 Expo 项目克隆到我的新 MacBook 上。我已经使用yarn安装了软件包和expo global，但没有运气运行

expo start

。错误信息如下：

(node:39137) UnhandledPromiseRejectionWarning: /Users/hurraychak/.config/yarn/global/node_modules/@expo/cli/build/src/api/rest/client.js:28
    name = "ApiV2Error";
         ^

我在互联网上找不到任何人讨论此错误。我发现运行时显示此错误消息

expo

。请帮我解决这个问题，谢谢！

Answer 1

我已通过运行

nvm use18

使用最新的节点版本解决了该问题。

之前，我尝试通过命令和下载两种方式升级node，但系统仍然使用10.xx.xx版本的node，而我没有意识到这一点。

Answer 2

HurrayChak 的上述答案基本上对我有用，但最初我使用 WebStorm 时感到困惑。

我需要转到“设置”->“语言和框架”->“Node.js”并指向那里的正确节点版本。从 WebStorm UI 运行 package.json 脚本时，在 WebStorm 终端窗口中运行 nvm use 18 不起作用。
