构建 JS 包时 Expo 启动错误：在 HMRClient.js 中输入类型转换

如何解决构建 JS 包时 Expo 启动错误：在 HMRClient.js 中输入类型转换

问题：

我最近在我的博览会项目 (React Native) 中遇到了阻塞问题。

类型转换表达式应该用括号括起来

我检查了我的代码，没有发现任何会导致此问题的更改。

当我输入使用 MetroBundler 启动世博会建筑（外壳）的说明时，它总是抛出一个错误。

expo start
Expo DevTools is running at http://localhost:19002 opening DevTools in the browser... (press shift-d to disable) Starting Metro Bundler
错误：

Failed building JavaScript bundle.
SyntaxError: C:\xamppN\htdocs\mobile-new\node_modules\react-native\Libraries\Utilities\HMRClient.js: The type cast expression is expected to be wrapped with parenthesis (284:31)

  282 | function flushEarlyLogs(client) {
  283 |   try {
> 284 |     pendingLogs.forEach(([level: LogLevel,data: Array<mixed>]) => {
      |                                ^
  285 |       HMRClient.log(level,data);
  286 |     });
  287 |   } finally {

类型转换表达式应该用括号括起来

我试过了：

编辑目标文件，它在节点模块内，不是非常有效，如果我以后必须安装纱线。
删除所有 node_modules 并重新安装无效
将世博会更新到最新版本，没有改变任何东西，同样的错误
