cygdb ImportError:没有名为'Cython'的模块

Question

我想调试我的Cython代码,并按照这里描述的确切步骤.我的Cython代码编译($ cython --gdb xxx.pyx然后$ python setup.py build_ext --inplace)但似乎cygdb在我的系统上无法正常工作.我使用的是Ubuntu 14.04,Python 2.7.6,Cython 0.23.4.我也尝试过另一个系统(Ubuntu 15.04),但也没有运气.也没有重新安装Cython工作.

$ python -c 'import Cython' 适用于我的系统,我相信这表明Cython已正确安装.

我用Google搜索,但找不到解决方案.如果有什么我错过了,请指出.

$ cygdb .

Answer 1

正如@MarkPlotnick所指出的那样,问题是"Ubuntu的最新版本有一个使用Python3的gdb".

要测试本地gdb使用的Python版本:

$ gdb
(gdb) python import sys; print(sys.version)

我常说3.4.x,这就是问题所在.

要解决它,我重新编译了我的gdb ./configure --with-python=python2.有关详细信息,请参阅此处.

我不确定这是否是最好的解决方案,因为我是Cython和cygdb的新手.如果有,请指出.
