在 Ubuntu 12.10 中安装 Miramath

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):
  File "main.py", line 28, in <module>
    from mainwindow import *
  File "/home/usama/Downloads/miramath/mainwindow.py", line 24, in <module>

    from polarplotwidget import PolarPlotWidget
  File "/home/usama/Downloads/miramath/polarplotwidget.py", line 29, in <module>
    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

The following modules will be built: ['iqt', 'Qwt5'].

Setup the PyQwt package build.
sip invokation:
'/usr/bin/sip -b tmp-iqt5qt4/iqt5qt4.sbf -c tmp-iqt5qt4   ../sip/iqt5qt4/IQtModule.sip'
sh: 1: /usr/bin/sip: not found
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...
Traceback (most recent call last):
  File "main.py", line 77, in <module>
    main(sys.argv)
  File "main.py", line 51, in main

    exec symbolics_init_program in self.symbolics_global_namespace    # execfile goes away in 3.0
  File "<string>", line 91, in <module>
AttributeError: 'module' object has no attribute 'abs'

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
