反应本机开发服务器错误 500

Question

嘿，我正在尝试使用 react-native 制作我的第一个应用程序，但在尝试安装 react-navigation 和 react-navigation 堆栈后遇到了问题。

当我尝试运行 react-native start 时出现此错误：

 BUNDLE  [android, dev] ./index.js ???????????????? 57.2% (431/570)::ffff:127.0.0.1 - - [19/Feb/2020:23:06:17 +0000] "GET /index.bundle?platform=android&dev=true&minify=false HTTP/1.1" 500 - "-" "okhttp/3.12.1"
error: bundling failed: Error: Unable to resolve module `@react-native-community/masked-view` from `node_modules/react-navigation-stack/lib/module/vendor/views/MaskedView.native.js`: @react-native-community/masked-view could not be found within the project.

但是我的节点模块文件夹中有 react-native-community 并尝试再次安装它，但是当我执行 npm install react-native-community 时它似乎不存在。

此外，我不确定这是否相关，但是当我执行 react-native run-android 时，它现在在 app:installDebug 步骤中停留在 99%。

编辑：固定需要做 npm install @react-native-community/masked-view

在您的项目中安装它

expo install react-native-gesture-handler react-native-reanimated react-native-screens react-native-safe-area-context @react-native-community/masked-view
