RNTester doesn't work

[tipoc123]

🐛 Bug Report

I can't force to work your sample RNTester according to manual https://github.com/facebook/react-native/tree/master/RNTester

To Reproduce

1. git clone https://github.com/facebook/react-native.git. It's OK!
2. cd react-native
3. npm install. It's OK, but shows some warnings:

npm WARN @react-native-community/cli@1.4.2 requires a peer of react-native@^0.59.0 but none is installed. You must install peer dependencies yourself.
npm WARN eslint-config-fbjs@2.0.1 requires a peer of babel-eslint@^7.2.3 but none is installed. You must install peer dependencies yourself.

4. Prerequisites steps (https://facebook.github.io/react-native/docs/building-from-source.html#android):
   a) Set ANDROID_SDK and ANDROID_NDK (in ~/.bash_profile).
   b) Create RNTester/android/local.properties (with sdk.dir and ndk.dir properties within).
5. ./gradlew :RNTester:android:app:installDebug. It's OK. Apk was installed on my android STB device.
6. ./scripts/packager.sh. It's FAILED. Output:
   error Unable to find React Native files. Make sure "react-native" module is installed in your project dependencies.

Then I open installed RNTesterApp on my device:

Logcat error:

Then I close RNTesterApp and run it again. It shows only white screen. Logcat:

Can you run react-native info and edit your issue to include these results under the Environment section?

If you believe this information is irrelevant to the reported issue, you may write `[skip envinfo]` alongside an explanation in your Environment: section.

I ran next command in the cloned repository:

tipoc@tipoc-MS-7817:~/Desktop/react-native$ react-native info
Command `info` unrecognized. Make sure that you have run `npm install` and that you are inside a react-native project.

Thanks. I am on it.

Still doesn't work. The same steps, the same errors.

Did you try to install RNTester by yourself?

[cdskill]

Have you started packager? Run yarn start from root of React Native.
