我尝试通过下载来构建此应用程序http://sourceforge.net/projects/miramath/?source=dlp在此过程中已经下载了+500mb数据，但在某一时刻我不断失败...这是我安装许多依赖项后最终得到的输出：
sudo python main.py
Traceback (most recent call last):

class PolarPlotWidget(Qwt.QwtPolarPlot):
AttributeError: 'module' object has no attribute 'QwtPolarPlot'
所以我通过下载了 PyQwthttp://sourceforge.net/projects/miramath/files/PyQwt-Polar/
按照手册我导航到配置文件夹并运行：
python configure.py -Q ../qwt-5.2

SIP failed to generate the C++ code.
我该如何解决这个问题？
上述问题通过安装解决：python-qt4-dev libqwt-dev python-sip-dev python-dev
成功构建 PyQwt 后，我在运行 miramath 时遇到一个新错误
python main.py
running...

问题已解决@green7 的回答如下
答案1
- 打开文件
symbolics_init.py。 - 转至第 行
91。 sympy.abs用。。。来代替sympy.Abs
