我正在本地环境中克隆现有的 react 本机应用程序，但每次运行时react-native run-ios都会出现以下错误：

** BUILD FAILED **

react-packager 中的这个错误：

当我运行react-native run-ios我克隆的 repo 时，我只会收到此错误。但是当我创建一个新的 react-native 应用程序时，一切正常。我尝试了一切：杀死服务器，再次卸载和安装节点，删除我的 node_modules 文件等，但我仍然无法解决这个问题。任何帮助将非常感激。谢谢。

对我来说，我卸载watchman然后重新安装它brew，如下所示：

npm r -g watchman 
brew install watchman

在编写反应原生应用程序时，我遇到了以下问题。这似乎是 watchman 的错误，所以我们需要重新安装它：

brew remove watchman

brew install watchman

我希望它有所帮助，

尝试运行 jest watch 时出现同样的错误。对我来说简单的解决方案是通过 npm 安装 fsevents 模块（我假设这是您的错误消息告诉您的内容）。我也在使用 React 应用程序，并且遇到了其他类似的错误。

希望这可以帮助！

这发生在create-react-app我身上。我通过更新解决了这个问题react-scripts

yarn add react-scripts@latest

然后删除node_modules，重新安装

yarn

有时此问题可能与您正在运行的节点版本有关。如果您使用的是 nvm，请尝试切换到不同的节点版本并查看它是否修复。它在类似的问题上对我有用。

就我而言，在 MacOS 更新之后，我需要更新版本的yarn.

curl --compressed -o- -L https://yarnpkg.com/install.sh | bash
