appium安装

郭大气儿

执行命令：appium -v.  出现以下报错：
UnhandledPromiseRejectionWarning: Error: ENOENT: no such file or directory, rename '/Users/guohongfei/Library/Application Support/appium-desktop/Settings-tmp' -> '/Users/guohongfei/Library/Application Support/appium-desktop/Settings'

UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)

求助啊，万分感谢
