我通常运行expo-start或expo-start-c，浏览器将在localhost:119000自动打开，并显示metro bundler详细信息，其中显示qr代码、连接：tunnel、lan、local，当然还有应用程序的exp:地址。
突然，当我运行expo启动时，浏览器不再打开。当我导航到localhost:119000时，它显示一个json转储：
{"name":"litplans","slug":"litplans","version":"1.0.0","orientation":"portrait","icon":"./assets/icon.png","userInterfaceStyle":"light","splash":{"image":"./assets/splash.png","resizeMode":"contain","backgroundColor":"#ffffff","imageUrl":"http://127.0.0.1:19000/assets/./assets/splash.png"},"updates":{"fallbackToCacheTimeout":0},"assetBundlePatterns":["**/*"],"ios":{"supportsTablet":true,"bundleIdentifier":"com.mallsecinc.litplans"},"android":{"adaptiveIcon":{"foregroundImage":"./assets/adaptive-icon.png","backgroundColor":"#FFFFFF","foregroundImageUrl":"http://127.0.0.1:19000/assets/./assets/adaptive-icon.png"}},"web":{"favicon":"./assets/favicon.png"},"_internal":{"isDebug":false,"projectRoot":"C:\sites\apps\litplans","dynamicConfigPath":null,"staticConfigPath":"C:\sites\apps\litplans\app.json","packageJsonPath":"C:\sites\apps\litplans\package.json"},"sdkVersion":"45.0.0","platforms":["ios","android","web"],"developer":{"tool":"expo-cli","projectRoot":"C:\sites\apps\litplans"},"packagerOpts":{"scheme":null,"hostType":"lan","lanType":"ip","devClient":false,"dev":true,"minify":false,"urlRandomness":"2x-kif","https":false},"mainModuleName":"node_modules\expo\AppEntry","__flipperHack":"React Native packager is running","debuggerHost":"127.0.0.1:19000","logUrl":"http://127.0.0.1:19000/logs","hostUri":"127.0.0.1:19000","bundleUrl":"http://127.0.0.1:19000/node_modules%5Cexpo%5CAppEntry.bundle?platform=ios&dev=true&hot=false&strict=false&minify=false","iconUrl":"http://127.0.0.1:19000/assets/./assets/icon.png"}
我做的唯一不同的事情是卸载和安装node.js.
为了解决问题，我做了以下操作：
- 试着运行一个现有的博览会项目
- 列出项目
- 启动一个全新的世博项目
- 删除nodemodule并重新安装
- 卸下expo模块并重新安装
Metro Bundler UI在expo-cli@6.0.0

对于我来说，使用"开始"："博览会开始"；而不是"；"开始"："expo-start-dev客户端"；如果你分享你的依赖关系，这可能会对有所帮助
