こんなのが無限に出る。

あとたまにだけどこんなのも出てるかも。

解決方法

metro.config.jsに以下を追加する。

config.resolver.disableHierarchicalLookup = true

こんな感じ。

// 省略
function withMonorepoPaths(config) {
  const projectRoot = __dirname;
  const workspaceRoot = path.resolve(projectRoot, "../..");

  config.watchFolders = [workspaceRoot];
  config.resolver.nodeModulesPaths = [
    path.resolve(projectRoot, "node_modules"),
    path.resolve(workspaceRoot, "node_modules"),
  ];
  config.resolver.disableHierarchicalLookup = true; // 追加

  return config;
}
