因此，我跳入了别人的应用程序，他们无法帮助我解决此问题，但对他们来说“开箱即用” 这样我就可以在终端上成功构建。 但是，当我启动模拟器时，该应用程序将启动，但屏幕黑屏，文本为红色背景：
"unable to load script. Make sure you're either running a Metro server (run 'react-native start)
or that your bundle 'index.android.bundle' is packaged correctly for release."
如果我按R重新加载，文本将更改：
Could not connect to development server. Try the following to fix the issue:
Ensure that the packager server is running.
Ensure that your device/emulator is connected to your machine and has USB debugging enabled - run 'adb devices' to see a list of connected devices
Ensure Airplane Mode is disabled
If you're on a physical device connected to the machine, run 'adb reverse tcp:8081 tcp:8081'
to forward requests from your device
If your device is on the same Wi-Fi network, set 'Debug server host & port for device' in 'Dev settings'
to your machine's IP address and the port of the local dev server - e.g 10.0.1.1:8081
尝试清除缓存，甚至在Linux，Windows和Mac上运行，但都无济于事。 任何建议将不胜感激。
如果我按R，在都会区中的消息是
React Native: No apps connected
sending äreload' to all React Native apps failed.

这是终端转储：

error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:
- react-native-push-notification (to unlink run: "react-native unlink react-native-push-notification")
- react-native-share (to unlink run: "react-native unlink react-native-share")
- react-native-system-setting (to unlink run: "react-native unlink react-native-system-setting")
- rn-range-slider (to unlink run: "react-native unlink rn-range-slider")
This is likely happening when upgrading React Native from below 0.60 to 0.60 or above. Going forward, you can unlink this dependency via "react-native unlink <dependency>" and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.
Read more about autolinking: https://github.com/react-native-community/cli/blob/master/docs/autolinking.md
