I am using Python 3.7.

Could you please help me?

Thank you

astroid 2.1.0 is only available on Python 3. Your scrapinghub.yml is not specifying any (py3) stack so it picks the default one which is scrapy-1.3 on Python 2.7. You need to specify a Python 3 stack by adding the suffix -py3 to the stack. See: https://support.scrapinghub.com/support/solutions/articles/22000200402-scrapy-cloud-stacks
