I execute commandreact-native run-ios.
将显示无法加载捆绑包。
我试过....
-
删除node_modules文件夹 -
rm -rf node_modules&&npm install -
重置打包程序缓存 -
rm -fr $TMPDIR/react-*或node_modules/react-native/packager/packager.sh --reset-cache -
透明守望者手表 -
watchman watch-del-all
但问题没有解决。
请查看错误屏幕截图。
谢谢。

更新：
我尝试删除node_modules并将项目移动到桌面。
还是同样的问题。

清理地铁捆绑器：rm -fr $TMPDIR/metro* 我不确定地铁文件在窗口中的确切位置，但搜索并删除它们。您也可以尝试更改项目名称并在package.json中提高项目版本
"name": "projactname",
"version": "0.0.1",
如果在到目前为止执行的所有步骤后仍然遇到相同的问题，则很可能是应用逻辑中的某个问题。通过在应用程序中创建某种hello world程序来测试它.js而不是加载项目文件。在项目文件的树中向下重复此操作，直到找到问题为止。
问题解决了。我在.babelrc中进行了更改：
"presets": ["react-native-stage-0"]
自
"presets": ["react-native"]
