-o : The term '-o' is not recognized as the name of a cmdlet, function, script file, or operable program.

I installed the tool and its requirements, I have the version 1.0.0 but when I started using it on windows10, always I have this error on the out put path:

safaribooks-downloader -d -b 9781484224427 -u myOreillyEmail -p myPassword -o "D:\\Books\\testbook.epub"

Thank you!
