Hello, I am trying to use 0.3.0, but get an error when trying to login:

>>> from usgs import api
>>> api.login("user","password",save=True)

Hi @sbrunato - have you previously used this library? When save=True during login, a hidden file is written to the user's home directory, $HOME/.usgs. If that file is lingering from a previous login using an older version, it might trigger the JSON parse error you're seeing.

Can you try deleting the .usgs file if it exists?

Thank you very much @kapadia, deleting ~/.usgs fixed the issue
