I had installed Appium Library: 1.5.0.6 with Python 3.6.7 & RobotFramework: 3.2.1. But while adding AppiumLibrary to RED.xml it throwing below exception:

RED was unable to find classes/modules inside ‘C:\Users\A1029532\AppData\Local\Programs\Python\Python36\Lib\site-packages\AppiumLibrary\__init_\_.py’ module  
Following exception has been thrown:

Appium Lib is using python3’s typing hints which are not compatible with Jython 2.7.2 that looks like what RED is been executed on…

Actually, its Appium-Python-Client which is dependency of robotframework-appiumlibrary which is not compatible with 2.7.2 as it is shipped now …
