Unable to start server with either the "both" or the "ios" flags. Help needed!

[jhumphrey-rsc]

I have went through all the setup steps and can successfully start the device grid up if I run the following command:

appium server -ka 800 --use-plugins=device-farm,appium-dashboard,execute-driver --plugin-device-farm-platform=android

However, if I try to change platform to either ios or both the appium instance crashes. Here are the logs if I set the flag to both:

Does anyone have any input as to what the problem might be? As mentioned earlier, it works very well if I pass the "android" parameter. Thanks in advance!

@jhumphrey-rsc can you tell me what happens when you run the command in your terminal

ios listen

[jhumphrey-rsc]

I believe I have it working now finally. It looks like there was an issue with adding the variable for go-ios to my bash profile. Thank you for your response!

Hello, I have the same issue with the simulator iPhone 14 in Mac M2.

Here are my steps:

1. Installed Appium plugins: device-farm & dashboard
2. Install go-ios by running the CLI: npm install -g go-ios
3. Set the environment variable in zshrc file. E.g. GO_IOS = /usr/local/lib/node_modules/go-ios/dist/go-ios-linux-amd64_linux_amd64/ios
4. Launch the server: appium server -ka 800 --use-plugins=device-farm,appium-dashboard -pa /wd/hub --plugin-device-farm-platform=ios
5. Got the failure. The details log is at https://gist.github.com/lengochoangminh/1029aaf29f32aa31e965dbad8dca039a

Appreciate for help

Hi @saikrishna321,

I have set an environment GO_IOS in ~/.zshrc file as below and am sure that it's a valid path
export GO_IOS="/usr/local/lib/node_modules/go-ios/dist/go-ios-linux-amd64_linux_amd64/ios"

Also double check for GO_IOS in the terminal by CLI: echo $GO_IOS. But I still failed to start the Appium server ...

Note that I have run it successfully for the Android parameter

[saikrishna321]

export GO_IOS="/usr/local/lib/node_modules/go-ios/dist/go-ios-linux-amd64_linux_amd64/ios" in the screenshot you attached above I see a error when you run the entire path

[lengochoangminh]

hmm... I found the root cause ... all good now. Appreciate your kind support @saikrishna321

[saikrishna321]

@lengochoangminh What was the issue?

[lengochoangminh]

LOL ... I pointed to the wrong OS. It should be export GO_IOS="/usr/local/lib/node_modules/go-ios/dist/go-ios-darwin-amd64_darwin_amd64/ios"
