我使用的是 Macbook，当我尝试创建 React Native 应用程序时，它会抛出 ESOCKETTIMEDOUT 错误。

我尝试清理 npm 和 yarn 缓存，但没有帮助。

我可以通过我的浏览器下载https://registry.yarnpkg.com/lodash/-/lodash-4.17.11.tgz文件，所以它不可能是网络问题。

【解决方案1】：

在慢速网络上检索大包时遇到同样的问题。正如comment 所建议的那样，增加安装包的网络超时对我有用。

首先，预先创建您的项目目录，然后在其中创建一个.yarnrc 文件，其中包含以下内容：

network-timeout 600000

现在，只需从项目的父目录运行react-native init <project_name> 命令即可。

相当于像这样运行yarn：

yarn install --network-timeout 600000
