cql支持python 3吗？

Question

cql是否支持python3？

我试着用pip安装，但是失败了。

实际上，cql依赖于Thrift，它可能不支持python3。

有什么解决方案吗？

Answer 1

Thrift确实明确地不支持Python3，它的元数据被标记为只支持Python2，安装它会给你一个语法错误。

解决方案是联系Thrift的作者，帮助他们进行port to Python 3。完成后，帮助端口cql。更新通常很简单(除了在某些特殊情况下)和乐趣！

Answer 2

不，cql库是与Python3不兼容的。它依赖于thrift，这是一个本身与Python3不兼容的包：

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:

thrift和cql都需要首先移植。

Answer 3

对于Python3，您可以使用CQLEngine。
