How to correctly deploy a viro react project to a ready-made example on a smartphone?

Question

JavaScript

Hello!
I'm trying to install viro react for a long time. I tried to do according to these guides: site click and one more, click .
You need to windowsexpand the project.
I switched to node v10.19.0because I was tired of dancing and dancing. It seems that everything started to start, but it still does not work (2).
I did this (1) :

• npm install -g react-native-cli react-viro-cli
  
• react-viro init test_app
  
• npm start= error

  "." не является внутренней или внешней
  командой, исполняемой программой или пакетным файлом.
  npm ERR! code ELIFECYCLE
  npm ERR! errno 1
  npm ERR! [email protected] prestart: `./node_modules/react-viro/bin/run_ngrok.sh`
  npm ERR! Exit status 1
  npm ERR!
  npm ERR! Failed at the [email protected] prestart script.
  npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
  
  npm ERR! A complete log of this run can be found in:
  npm ERR!     C:\Users\User\AppData\Roaming\npm-cache\_logs\2020-03-03T17_11_44_092Z-debug.log

  
  

  //package.json
  "scripts": {
      "prestart": "./node_modules/react-viro/bin/run_ngrok.sh",
      "start": "node node_modules/react-native/local-cli/cli.js start",
      "test": "jest"
    },

  
  

Option (2) :

• react-native init test_app --version=0.59.3
  
• cd test_app && npm install -S -E react-viro
  
• npm run startin the console everything started up, and then what?
  
• installed ngrok, saved API key, launchedngrok http 80
  
• запрос идет, НО 502 ошибка
  

There are no more instructions. Correct, describe the correct / correct installation on windows-android. Thank you.
