cql是否支持python3？

我尝试用pip安装但是失败了。

实际上cql依赖于Thrift，它可能不支持python3

任何解决方案??

Answer 1

Thrift确实明确地不支持Python 3，它的元数据被标记为仅支持Python 2，并且安装它会给你一个语法错误。

解决方案是联系Thrift的作者并帮助他们port to Python 3。一旦完成，请帮助端口cql。更新通常很容易（除了在某些特殊情况下）并且很有趣！

Answer 2

不，cql库不与Python 3兼容。它依赖于thrift，一个不 Python 3兼容的软件包本身：

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本身在cqltypes.py中使用相同的过时语法：

except (ValueError, AssertionError, IndexError), e:

首先需要移植thrift和cql。

Answer 3

对于Python 3，您可以使用CQLEngine。
