Does cql support python 3?

Does cql has support python3?

I tried to install with pip but it failed.

In fact cql is dependent on Thrift which probably not support python3

Any solution??

回答1:

Thrift does indeed explicitly not support Python 3, it's metadata is marked as supporting Python 2 only, and installing it gives you a Syntax error.

The solution is to contact the authors of Thrift and help them port to Python 3. and once that is done, help port cql. Updating is usually easy (except in some special cases) and fun!

回答2:

No, the cql library is not compatible with Python 3. It relies on thrift, a package that is not Python 3 compatible itself:

Traceback (most recent call last):
  File "<string>", line 16, in <module>
  File "/Users/mj/Development/venvs/stackoverflow-3.3/build/thrift/setup.py", line 45
    except DistutilsPlatformError, x:
                                 ^
SyntaxError: invalid syntax

cql itself uses the same obsolete syntax in cqltypes.py:

except (ValueError, AssertionError, IndexError), e:

Both thrift and cql need to be ported first.

For Python 3, you can use CQLEngine.
