No bundle url present

[soutot]

Description

I noticed some people recently asking about this "No bundle url present" error and I just faced it myself.

Reproduction

I had just run ˜react-native init projectName˜, setup my App.js file (a simple Hello World), called it in both iOS and Android indexes and run ˜react-native run-ios˜. Then the No bundle url present error appeared.

Solution

I tried to delete my node_modules and npm install, close the packager and run the project again, but it could only be solved when I follow the steps given here (http://stackoverflow.com/questions/42610070/what-means-of-no-bundle-url-present-in-react-native).

• Run "react-native run-ios"
• When the error appears, run "npm install"
• Then run "react-native run-ios" again.

Additional Information

This is the first project I started using RN 0.42. Since it never happened before and I am not the only one facing this issue, I guess it should be taken a closer look to it.

Here's my package.json:

{
	"name": "myProject",
	"version": "0.0.1",
	"private": true,
	"scripts": {
		"start": "node node_modules/react-native/local-cli/cli.js start",
		"test": "jest"
	},
	"dependencies": {
		"react": "~15.4.1",
		"react-native": "0.42.0"
	},
	"devDependencies": {
		"babel-jest": "19.0.0",
		"babel-preset-react-native": "1.9.1",
		"jest": "19.0.2",
		"react-test-renderer": "~15.4.1"
	},
	"jest": {
		"preset": "react-native"
	}
}

If I can be more helpful to make any further test, it would be a pleasure.

Having the same issue now. Not sure what changed.

Same problem.

I believe it's an issue with XCode. That's he only thing I can figure. It updated and all hell broke loose.

What if you run npm start in console?

[qyvip]

Same problem.

I found
JsCodeLocation = [[RCTBundleURLProvider jsBundleURLForBundleRoot:@ sharedSettings] "index.ios" fallbackResource:nil];
Take effective address not, this happens in connection to the network situation (and not all networks such), when this happens, disconnected from the network, I think, in a virtual machine can run in localhost:8081
This is the way I am

[edwardofclt]

Nope. I tried everything.

Yes, this is the IOS code, I simply look at the code, here will automatically take the local IP, but obviously, did not take, Android I have not tried, but this is obviously different from the IOS code

My situation when I changed a network environment, it is normal, very clever, when I met the home
I try to print out the automatic access to the full address, are taken to return to the null, at the same time, APP will be waiting for the start of the case, this is the local address

NSLog (@ absoluteString:%@), [jsCodeLocation absoluteString]);
NSLog (@ host:%@), [jsCodeLocation host]);
NSLog (@ port:%@), [jsCodeLocation port]);

When I will

jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

Modified into

jsCodeLocation = [NSURL URLWithString:@"http://127.0.0.1:8081/index.ios.bundle?platform=ios&dev=true"];

This time can be a normal start, but after entering the application of remote image loading, it seems wrong
This is just a point of view, and there is no concrete solution

I have gotten that message when the packager is not running when the app is launched on iOS. Typically I have to completely kill the app and launch again after I have started the packager. Can you guys be sure that you have the packager running prior to launching the app?

[soutot]

@rmevans9 in my case the packager was running as always. The solution I posted is done while the packager and the app are running. That's the only way I found by now to handle this. I belive there's something going wrong when the modules are installed on react-native init. I have to do some tests before assurance it

[qyvip]

Yes, the packager is already running. I can access it through the browser

[despreston]

I am also seeing this issue on RN 0.42.0

Same problem and I run "npm install" and "react-native run-ios" ,the problem seems to be not solved yet.

[yustada]

I am seeing same problem @0.42.0 and
"npm install" does not solve it.
