Hi everyone,

I was trying to launch safari and do some testing on real device. When I ran my test, I always get “fruitstrap quit unexpectedly” popped out like this:  
 ![](https://discuss.appium.io/uploads/default/original/2X/2/2584993376ed3ef3b83c39223753ff9eaf6e1039.png)

Here is the error (MY\_DEVICE\_UDID represents my iphone udid):  
`org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: Unable to install [/var/folders/y1/qs7n7tb92c15ltn3y0ksfjkc002rd1/T/116117-65663-khwwkw/submodules/SafariLauncher/build/Release-iphoneos/SafariLauncher.app] to device with id [MY_DEVICE_UDID]. Error [Error: Command failed: /bin/sh -c /Applications/Appium.app/Contents/Resources/node_modules/appium/build/fruitstrap/fruitstrap install --id MY_DEVICE_UDID --bundle "/var/folders/y1/qs7n7tb92c15ltn3y0ksfjkc002rd1/T/116117-65663-khwwkw/submodules/SafariLauncher/build/Release-iphoneos/SafariLauncher.app"]) (WARNING: The server did not provide any stacktrace information)`

Here is my settings:  
 ![](https://discuss.appium.io/uploads/default/original/2X/f/f7b18cf1ac18fff9dc0dbc3a2d5c402c49f8f294.png)

`DesiredCapabilities capabilities = new DesiredCapabilities(); capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, "iOS"); capabilities.setCapability(MobileCapabilityType.PLATFORM_VERSION, "8.3"); capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, "iPhone"); capabilities.setCapability(MobileCapabilityType.BROWSER_NAME, "Safari"); iosDriver = new IOSDriver(new URL(http://127.0.0.1:4725/wd/hub), capabilities); iosDriver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS); return iosDriver;`

I followed every step in this instruction: [Mobile Web automation on iOS real device – Safari](https://discuss.appium.io/t/mobile-web-automation-on-ios-real-device-safari/4900) except ./bin/ios-webkit-debug-proxy-launcher.js -cMY\_DEVICE\_UDID -d  
because I got error:  
`module.js:339  
throw err;  
^

Error: Cannot find module ‘underscore’

I am not sure if this is related.

Can someone please help? Thanks ahead!!

I wonder what version of Appium you are using? Fruitstrap has not worked for a while now. Current versions use ideviceinstaller.

How do you feel about updating to the latest? Is there some reason that you haven’t?
