I am trying to install scrapy 0.24 in freebsd (MariaDB) system but when I try to run it I have an "keyError: 'z'" which I don't know what it means... I tried to debug it with no success.

I'll try to install also scrapy 0.22 in freebsd just in case that could be the problem
Thanks a lot!!

What could be the root-cause?
I found a solution.
If I disable the python-hunter library it works.
I guess python-hunter is not compatible with Python2.7 any more.
That's fine for my use case. I this case I can remove the library (although it is a great tracing library).
I installed pytest-bdd at /home/marlu/.local using python setup.py install --user, since I don't have admin privileges. Both python2.7 and pytest are located at /usr/bin/. When I check if pytest-bdd is working correctly by running py.test --version I get an error, could anyone tell me why? Thanks!

I am using the flask-sqlalchemy extension with alembic for migrations. When I try to add a new migration file and upgrade the schema to the latest one, I get the following error:
AttributeError: 'int' object has no attribute '_compiler_dispatch'
The content of the migration file:

from alembic import op

Alright, I just went through this same issue. I'm not using flask-sqlalchemy, just straight alembic, but it should be identical.
Second, it worked for me with sa.Integer with no parentheses, so I would recommend that.
The alembic docs say:
When producing MySQL-compatible migration files, it is recommended that the existing_type, existing_server_default, and existing_nullable parameters be present, if not being altered.
Since it seems you are not altering these columns, the docs suggest they should be present. So:
Remove nullable, type_, and server_default. They are not being altered.
Keep existing_nullable, existing_type, and existing_server_default.
I have a strange problem. I am using a program developed in python 2.7 (not by me). The software use matplotlib and I installed it fine. But somehow I still get this error. Anyone has any idea what to check?

It's very clear:
django.core.exceptions.ImproperlyConfigured: IndentationError('unexpected indent', ('/etc/sentry.conf.py', 58, 1, " SENTRY_URL_PREFIX = 'http://logs.felipeurrego.com'\n"))
You have a unwarranted space before the configuration variable SENTRY_URL_PREFIX in your /etc/sentry.conf.py. Python requires that everything is uniformly indented in your source code files.
