React-native: react native cmd+R cmd+D Shake Gesture doesn't work not refreshing

Created on 27 Jul 2015 · 29Comments · Source: facebook/react-native

when I edit the js file and hit Cmd-R in the simulator, nothing happens.
It was work fine by yesterday. I don't kown what happened. I try to restart , full install every software.
It doesn't work . My simulator Hardware > Shake Gesture doesn't work too.
I try http://facebook.github.io/react-native/docs/troubleshooting.html#content and https://github.com/facebook/react-native/issues/306 methods , not work.
I think does the watchman is not connection in my simulator. How can I fix it ?

xcode - Version 6.4 (6E35b)
simulator - Version 8.4
watchman - 3.3.0
node - 0.12.7

Locked

Try command + shift + T. Your keyboard might be disabled.

@jaygarcia I tried . don't work. All the same. My keyboard could input the word . It connected to the simulator. How can I make sure the watchman was working on the simulator?

chunecai on 27 Jul 2015

Your bundle server might not be running. That server is what should connect to watchman. Does Xcode launch a server in your terminal when you run your app?

Do you see any errors in Xcode or the simulator?

ericvicenti on 27 Jul 2015

@ericvicenti When I run my app, there is no error, in my Xcode or on the simulator. My app was work fine . Just when I modify my js file , hit cmd+R ,the simulator doesn't work,not refreshing. I couldn't see any error. Just not response.

chunecai on 28 Jul 2015

Does the server run? (A terminal window should appear when you press run in Xcode)

ericvicenti on 28 Jul 2015

@ericvicenti yes, ofcourse. The server was running. When I modified the js file , request the index.ios.bundle, At the terminal console i could see the change.

[09:39:13] find dependencies
[09:39:13] find dependencies (66ms)
[09:39:13] transform
[09:39:14] transform (435ms)
[09:39:27] request:/index.ios.bundle
[09:39:27] request:/index.ios.bundle (9ms)

Just not working refreshing in my simulator.

@ericvicenti Also I make sure the watchman was working . In my terminal console , i run the command " ps -ef|grep watchman" , I could see the process code .

@chunecai when the simulator is active, can you go to the top menu and choose Hardware -> Shake Gesture? This should pop up a menu with a button that says Reload. If this works for you, then I believe there is a problem with your computer's keyboard configuration.

@ide It doesn't work . When I choose Hardware -> Shake Gesture , It was not pop anything .

chunecai on 28 Jul 2015

@ide I saw my computer's keyboard configuration , It was right , It was QWERTY keyboard .

chunecai on 28 Jul 2015

This is very strange... are you running the app in RELEASE mode maybe? The menu is enabled only in DEBUG mode.

@chunecai thank you. You saved me a load of time!

Can this fix please be added to https://facebook.github.io/react-native/docs/troubleshooting.html ? Those list of fixes are very good, and I believe this should be noted as well. Thanks, and Happy New Year everyone.

This might be a bit stack overflow-ish but I ran into the same problem.

My keyboard was disabled as @jaygarcia mentioned, but for some reason my hotkey is mapped to command + shift + K, not command + shift + T

From the simulator check "Hardware > Keyboard" and make sure "Connect Hardware Keyboard" is enabled.

I just update to RN0.43,and found that command + R work while command + D not work,anyone can help?

check the pod i use, found that I haven't imort 'DevSupport', so I can't use command + D to debug.

Try this.

I am also finding that CMD+D does not work while CMD+R does. just upgraded RN from 0.40 to 0.44
it is not an issue with keyboard being enabled, i have checked this. note that i run the project from xcode, starting npm server myself beforehand ("node node_modules/react-native/local-cli/cli.js start"). i do not use react-native run-ios (cmd+d works in this case). i need it to work when running from xcode (brownfield app)

Adding 'DevSupport' in the subspecs in my Podfile fixed it for me!

  pod 'React', :path => react_path, :subspecs => [
    'Core',
    'RCTText',
    'RCTImage',
    'RCTWebSocket',
    'RCTNetwork',
    'DevSupport'
  ]

It sadly doesn't work for me on 0.44 @julienfouilhe, I am pretty sure my scheme is on debug, I ran pod install and I have reset all the caches

Any clues?

Version 10.0 (SimulatorApp-745.10 CoreSimulator-375.21)

my version is 0.45, and config pod like below can fix this issue

pod 'React', :path => './ReactNative/node_modules/react-native', :subspecs => [
'Core',
'RCTText',
'RCTNetwork',
'RCTWebSocket',
'BatchedBridge',
'DevSupport',
]
pod "Yoga", :path => "./ReactNative/node_modules/react-native/ReactCommon/yoga"

post_install do |installer|

installer.pods_project.targets.each do |target|
if target.name == 'React'
target.build_configurations.each do |config|
if config.name == 'Debug'
config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['RCT_DEBUG=1','RCT_DEV=1','RCT_NSASSERT=1']
end
end
end
end
end
