Question

我正在尝试在Ubuntu 12.04上安装并运行Camelot框架。但从错误来看，问题似乎是sqlalchemy。我安装了camelot：

pip install camelot安装没有任何问题。我试图升级sqlalchemy和camelot，但是它会引发异常并且在我运行时不起作用：

python -m camelot.bin.camelot_admin

某些版本：

In [1]: import camelot

In [2]: camelot.__version__
Out[2]: '12.06.29'

In [3]: import sqlalchemy

In [4]: sqlalchemy.__version__
Out[4]: '0.8.0b2'

这是追溯：

Answer 1

我从0.8降级到sqlalchemy 0.7.8并清理了之前安装的一些文件。现在它很棒。

Camelot无法创建新项目
