For those coming with yarn 127 error code problem

Take a look on https://github.com/reactstrap/reactstrap/issues/711 Most probably you just need to run in console yarn :)

Replace your scripts values with these, and try again:

"scripts": {
    "ios": "react-native run-ios",
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest",
    "test:e2e":"npm run test",
    "test:e2e:build":"npm run build"  // THIS SCRIPT WILL STILL BREAK FOR YOU
},

The last two are the important ones!

You need to prefix a script command with npm run or yarn if the script references another script in your package.json.

So instead of a script calling navicotrackapp test it would call npm run test OR yarn test.

NOTE:

In you example it looks like the terminal is failing on the script navicotrackapp build. Know that you do not have a build script defined so if you replace the script with npm run build it will still fail. You'll need to add a build script in if you want it to work!

"scripts": {
    "ios": "react-native run-ios",
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest",
    "build": // DO SOMETHING HERE!!!!,
    "test:e2e":"npm run test",
    "test:e2e:build":"npm run build"
},

Just use https://app.netlify.com/drop to deploy manually on Netlify

first run this command

npm run build 
OR

Then drag and drop the build folder on the website above.

Try this, and please take care of the spaces.

It worked for me though. I added CI= in the capital before npm run build. Double-check if you did git add. , git commit -m "first commit" and git push -u origin before your final deployment.

Please check this netlify application image
