Code To Reproduce Issue [ Good To Have ]

No installed drivers, then appium driver install xcuitest , then Attempt to run test, get the above output.

/Users/user/.appium/node_modules/appium-xcuitest-driver/node_modules DOES NOT have the expected within /appium/driver.js

do you have an old appium home structure? try to rm -rf ~/.appium then try the whole thing again. otherwise, do you have an APPIUM_HOME variable set? and otherwise, paste the full set of logs

[jlipps]

yeah i think the way appium home is used changed between beta 37 and 40. glad it worked!
