Не удалось установить Appium

Question 1

Я пытаюсь установить Appium на Ubuntu 16.4 и используя этот ссылочный сайт, я застрял в команде npm install -g appium. Он показывает ниже ошибки:

npm WARN optional Skipping failed optional dependency /appium/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.1.2
npm ERR! Linux 4.10.0-37-generic

npm ERR! Tell the author that this fails on your system:

npm ERR! You can get information on how to open an issue for this project with:
npm ERR!     npm bugs appium-windows-driver
npm ERR! Or if that isn't available, you can get their info via:
npm ERR!     npm owner ls appium-windows-driver
npm ERR! There is likely additional logging output above.

npm ERR! Please include the following file with any support request:

Может кто-нибудь, пожалуйста, предложите мне способ преодолеть эту ошибку.
