appium/appium-ios-deviceの導入でつまづいた内容のまとめです。
環境
MacBookPro15 Mojave - macOS 10.14.6
事象
gulpが無いと言われたのでインスコへ
$ npm run watch
> appium-ios-device@1.2.1 watch /Users/gremito/git/appium-ios-device
> gulp watch
sh: gulp: command not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn

npm ERR! appium-ios-device@1.2.1 watch: `gulp watch`
npm ERR! spawn ENOENT
npm ERR!
npm ERR! Failed at the appium-ios-device@1.2.1 watch script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm WARN Local package.json exists, but node_modules missing, did you mean to install?
