Hi @pushpank

Are you behind any company proxy or firewall, if yes then you need to configure proxy first and then install.

Hope this will help.

Hello Ravi,

We are not using any proxy or firewall, it may be node install issue but i can not identify

[pushpank]

But in /Applications/Appium.app/Contents/Resources/node_modules/appium/bin> i found only one file > ios-webkit-debug-proxy-launcher.js

may its breaking it ?

Please suggest me further

npm install -g appium

If npm succesfully installed appium globally, you can launch appium by typing "appium" in your command line. But i see some NPM errors, so i assume it didn't. What happens when you directly type "appium" in your console ?

[ravikr42]

To check whether node and npm is working or not try below commands:

Node -v --> This will give you node version
npm -v --> This will give you npm version

Then try below command to install appium:

npm install -g appium

to install specific version use

npm install -g appium@version no

Tip : try giving some invalid version, if you are getting version error it means npm is hitting to appium server and version is being verified.

Let me know if this helps.

Regards
Ravi

@ravikr42 It appears to me that you're not calling "node appium" in the correct directory, can you try this?

cd /Applications/Appium.app/Contents/Resources/node_modules/
node appium

Or
cd /Applications/Appium.app/Contents/Resources/node_modules/appium
node .

[pushpank]

@sam
Its showing appium version but still not working for me shows arror as previous
srikantas-Mac-mini-3:node_modules RajShekhar_DiroLabs$ node appium

[sam_viz]

What errors are you talking about? Because as i see in the last logs you provided, Appium server started

Hello thanks for response , mine this is resolve by re change path of npm .
But now i am facing the issue in start node server with selenium grid, Selenium grid is running but when i start node server with json file "node appium --nodeconfig /Users/RajShekhar_DiroLabs/Desktop/node1.json -p 4730"
it shows me logs like
Appium] Welcome to Appium v1.5.2

} }

node is running but not on selenium grid can please suggest me in this case

[sam_viz]

[Appium] Unable to load node configuration file to register with grid: ENOENT: no such file or directory, open '/Users/RajShekhar_DiroLabs/Desktop/node1.json'

The error means that the server didn't find the file named "node1.json" in you desktop folder. Can you confirm that you're specifying the right path and file name?

P.S: before you launch appium node, make sure you launch selenium hub on the correct url 127.0.0.1:4444/grid/register

Thanks @sam for reply, its resolved now my mac is added some unicode in json.
Now two node server are running but my script are running only in one node do not why, can you suggest me in this

[email2vimalraj]

Use the applicationName capability in your node.json.
Refer: http://www.vimalselvam.com/2016/05/15/selenium-grid-for-appium-mobile-automation/

[pushpank]

Still with applicationName caps script is working only in one node

	}

Could you please post both of your node json and both capabilities from your test script?
