npm ERR！代码ELIFECYCLE-无法启动开发服务器

标签： react-native expo

我正在跟随React Native的走马路来开始创建应用程序，但是当我进入 “ npm start”一秒钟后，本地服务器关闭，我在cmd中收到以下错误：

对不起，代码量很大，我不确定您需要什么帮助。关于类似的问题： 我试过了： 步骤1：$ npm缓存清理--force

第2步：通过$ rm -rf node_modules文件夹删除node_modules，或通过进入目录并右键单击>删除/移至回收站来手动删除它。另外，也删除package-lock.json文件。

第3步：npm安装

要重新开始，$ npm start 它对我不起作用，但我首先找不到package-lock.json文件。 版本： node.js-v12.13.1 npm-6.12.1 世博会-3.11.1

1 个答案:

答案 0 :(得分：1)

您使用的节点版本（12.13.1）有问题。 从系统上卸载NodeJ，然后下载并安装NodeJS版本12.9.0 然后，您将不会面对您提到的问题。我和你有同样的问题。但是，它对我有用。
