ImportError: cannot import name 'Main' => Cannot install module with pip

[Gribouillis]

If you write pip install main, it means that you are trying to install this module from pypi, which calculates the price of a book from its title. Is it really what you want to do?

If python writes ImportError: cannot import name 'Main', it means that it cannot import a class or function or some other python object named Main. The solution is not to use pip. If you post the whole error traceback here, it will probably help us diagnose the error.
