react-native init 给出 ESOCKETTIMEDOUT 错误

Question

我正在使用 Macbook，当我尝试创建 React Native 应用程序时，它会引发ESOCKETTIMEDOUT错误。

我试图清理 npm 和 yarn 缓存，但它没有帮助。

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

在慢速网络上检索大包时遇到同样的问题。正如此评论所建议的那样，增加安装软件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包含以下内容的文件：

network-timeout 600000

现在，只需react-native init <project_name>像您一样从项目的父目录运行命令。

它相当于yarn像这样运行：

network-timeout 600000
