Unable to launch WebDriverAgent because of xcodebuild failure: spawn EACCES

The problem

Unable to launch WebDriverAgent because of xcodebuild failure: spawn EACCES is thrown when I’m running tests on the appium server installed using npm. However, when I start the appium server from Applications/Appium.app my tests work just fine.

Environment

• Appium version (or git revision) that exhibits the issue: 1.6.5 (both app and cli)
• Last Appium version that did not exhibit the issue (if applicable):
• Desktop OS/version used to run Appium: macOS 10.12.6
• Node.js version (unless using Appium.app|exe): 5.4.0
• Mobile platform/version under test: ios 10.3.1
• Real device or emulator/simulator: simulator iPhone 7 Plus
• Appium CLI or Appium.app|exe: both
• Xcode version: 8.3.3 (8E3004b)

Details

My installation steps:

brew install carthage
npm install -g appium
npm install -g authorize-ios
sudo authorize-ios

requirements.txt:

Appium-Python-Client==0.24
pytest==3.2.1
selenium==3.3.1

Also, I have automatic code signing in Xcode and Code Signing Identity: iOS Developer

Code To Reproduce Issue

Start appium server:

appium --webdriveragent-port 8100 -bp 4724 --selendroid-port 8080 --port 4723

Some relevant python code

from appium import webdriver
import os

app = os.path.abspath('ios/build/Build/Products/Debug-iphonesimulator/yourAppNameHere.app')
self.driver = webdriver.Remote(
    command_executor='http://127.0.0.1:4723/wd/hub',
    desired_capabilities={
        'app': app,
        'platformName': 'iOS',
        'platformVersion': '10.3',
        'deviceName': 'iPhone 7 Plus',
        'autoAcceptAlerts': True,
        'autoGrantPermissions': True,
    }
)

This happened to me on 2 different machines after upgrading appium versions. The fix I found was to uninstall and reinstall node (and appium then). My node installation is managed by Homebrew if that matters. Posting here in case someone else is affected.

Looks like the problem with the wrong simulator was because I started appium using sudo. And looks like the problem is solved. I tested the following:

1. This:

   sudo chown -R $USER /usr/local
   sudo npm install -g appium
   appium --webdriveragent-port 8100 -bp 4724 --selendroid-port 8080 --port 4723
   

2. And this:

   sudo chown -R $USER /usr/local
   npm install -g appium  # notice the missing of sudo here
   appium --webdriveragent-port 8100 -bp 4724 --selendroid-port 8080 --port 4723
   

And both of these worked. So my guess is that sudo chown -R $USER /usr/local was enough to solve the problem. I’ll close this issue and thank you.
