Do you have any require image like this:
你有这样的需求图片吗：
require("../assets/user.png")
require("../assets/user.png")
If yes then please check the image path. I'm facing the same issue, so I just corrected the path and the error is gone.
如果是，请检查图像路径。我面临同样的问题，所以我只是更正了路径，错误消失了。

1.I suggest restarting React. Just run the following commands:
1.我建议重启React。只需运行以下命令：
# Kill current processes
killall node -9
# Start React - Native
react-native start
# Run android
react-native run-android or react-native run-ios
That should do the trick.
这应该够了吧。
2.If it is not working then check your image path you have used. For example
2.如果它不起作用，请检查您使用的图像路径。例如
<Image
source={require("./images/logo.png")} // check your image path you have used

run these commands
运行这些命令
react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
and this command too
还有这个命令
rm ./node_modules/react-native/local-cli/core/__fixtures__/files/package.json
then run
然后运行
npm i && react-native run-android
or run-ios anything that is applicable
或 run-ios 任何适用的东西

I have faced this issue and here is how I fixed it.
我遇到了这个问题，这是我解决它的方法。
If you are sure that there is nothing wrong with your code you can try to restart process in port 8081.
如果您确定您的代码没有问题，您可以尝试在端口 8081 中重新启动进程。
Open your terminal and find process id with below command:
打开终端并使用以下命令查找进程 ID：
sudo lsof -n -i :8081 | grep LISTEN
Then use kill idwhere idis returned from lsof
然后使用从kill id哪里id返回lsof
After that just run you application
之后，只需运行您的应用程序
react-native run-android

I`ve faced the same issue. In my case basically, it is because of some broken/wrong paths in imports statements. The issue gets solved after correcting all the imports paths i.e styles, components, routers, reducers, actions etc., restarting the emulator and running the build again.
我遇到了同样的问题。就我而言，基本上，这是因为导入语句中有一些损坏/错误的路径。在更正所有导入路径（即样式、组件、路由器、减速器、动作等）后，问题得到解决，重新启动模拟器并再次运行构建。
