Now, enter the command on the command line: python transpire.py
Press ENTER. You will see the file will be compiled without any error.
Things go well when configuration is right
It is always recommended to check path variables when connecting to different components in the development environment. Otherwise, wizard based installations are easy in the Windows system.
