Instalando o Miramath no Ubuntu 12.10

Question

Eu tentei criar este aplicativo por meio de download no link & no processo já baixei + 500mb de dados, mas em um ponto eu estou constantemente falhando ... Esta foi a saída que finalmente consegui depois de instalar muitas dependências:

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>
    import worksheet
  File "/home/usama/Downloads/miramath/worksheet.py", line 37, in <module>
    import polarplot
  File "/home/usama/Downloads/miramath/polarplot.py", line 30, 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'

Por isso, fiz o download do PyQwt por meio do link

de acordo com o manual, naveguei para a pasta de configuração & correu:

python configure.py -Q ../qwt-5.2

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

Setup the PyQwt package build.
sip invokation:

sh: 1: /usr/bin/sip: not found
SIP failed to generate the C++ code.

Como posso resolver isso?

Os problemas acima foram resolvidos através da instalação: python-qt4-dev libqwt-dev python-sip-dev python-dev

Após criar com sucesso o PyQwt, enfrentei um novo erro ao executar o miramath

 python main.py
running...

Answer 1

• Abra o arquivo symbolics_init.py .
• Ir para a linha 91 .
• Substitua sympy.abs por sympy.Abs
