I am, just tried that and still won't load my javascript bundle. Can I ask what version of watchman you are running?

@AlexB801 4.9.0

Here is my package.json

{ "name": "UdaciFitness", "version": "0.1.0", "private": true, "devDependencies": { "react-native-scripts": "1.14.0", "jest-expo": "~27.0.0", "react-test-renderer": "16.3.1" }, "main": "./node_modules/react-native-scripts/build/bin/crna-entry.js", "scripts": { "start": "react-native-scripts start", "eject": "react-native-scripts eject", "android": "react-native-scripts android", "ios": "react-native-scripts ios", "test": "jest" }, "jest": { "preset": "jest-expo" }, "dependencies": { "expo": "^27.0.1", "react": "16.3.1", "react-native": "~0.55.2", "react-navigation": "1.5.11", "react-redux": "^5.0.6", "redux": "^3.7.2", "udacifitness-calendar": "^11.0.0" } }

Hmmm. Keep getting same error about react-native-scripts in node_modules.

jessequinn commented 6 years ago

@AlexB801 not sure, as I did not receive that message. Are you using NPM or YARN to start the app? I am successful with npm run ios.

AlexB801 commented 6 years ago

I've tried them all. lol always stops at the javascript bundle load error.

Ive tried everything and still no luck... though it worked using expo XDE

nguyenvu commented 6 years ago

When it says "Starting packager..." press the "q" key. To show QR code

Thank you sir, you make my night!

I've tried to reinstall 'exp' by: sudo npm install -g exp on Mac and the problem is solved.

If you did npm audit fix you might have updated your dependencies to latest versions and the problem is that REACT-NATIVE 0.56. DOESNT WORK WITH EXPO 27. You should use 0.55. REACT-NATIVE and never run npm audit fix but npm audit to fix manually

This works for me in package.json

"expo": "^27.0.1",
"react": "16.3.1",
"react-native": "~0.55.2",

here is table of compatabilities image

Even though i've lined up my versions to the table above (row with 0.55.0 react-native), i still get the following error:

Loading dependency graph...jest-haste-map: @providesModule naming collision: Duplicate module name: crud Paths: /Users/name/ProjectName/awsmobilejs/backend/cloud-api/itemsHandler/package.json collides with /Users/name/ProjectName/awsmobilejs/#current-backend-info/cloud-api/itemsHandler/package.json

This warning is caused by a @providesModule declaration with the same name across two different files.

Any idea to resolve this clash?
