The conflict is caused by:
    The user requested scrapy-utils 0.1 (from git+ssh://****@gitlab.conceptu.ind.br/wattpanel/scrapy_utils.git@2c5c4139878da555f29b547be1bd9ec5b21210eb#egg=scrapy_utils)

    bill-core 0.6.1 depends on scrapy-utils 0.1 (from git+ssh://****@gitlab.conceptu.ind.br/wattpanel/scrapy_utils.git@2c5c4139878da555f29b547be1bd9ec5b21210eb)

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
