Question

Metro Bundler 似乎没有加载...它正在打开和关闭，关闭前我看不到里面有任何东西运行ning。因此，模拟器未运行应用程序。

我在运行ning 之后收到错误：

我在之后找到了解决方案：

Replace the code with this one. The path of the file is -

node_modules\metro-config\src\defaults\blacklist.js

var sharedBlacklist = [
  /node_modules[\/\]react[\/\]dist[\/\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

并且运行在根项目文件夹中执行以下命令：

npm i -g jetifier
npx jetify
