我有一个PyQt4应用程序项目，我想在Windows上变成.exe。我cd到主脚本并运行pyinstaller SPCanalyse.py。当我尝试运行.exe时，我得到：
C:\Users\user\Documents\BMDanalyse\BMDanalyse\BMDanalyse>C:\Users\user\Documents
\BMDanalyse\BMDanalyse\BMDanalyse\dist\SPCanalyse\SPCanalyse.exe
Traceback (most recent call last):
File "<string>", line 12, in <module>
ImportError: cannot import name NavigationToolbar2QTAgg
SPCanalyse returned -1
阅读this我尝试将matplotlib.backends.backend_qt4agg import NavigationToolbar2QT添加到SPCanalyse.py的顶部，但无效。虽然我很惊讶我仍然有错误，因为看起来他们修好了。
我有matplotlib版本1.5.1，我确实在这个版本中找到了NavigationToolbar2QTAgg was removed，我肯定与我得到错误的原因有关。所以，如果它被删除，为什么我的代码会尝试导入它？如何防止尝试导入？
请注意，我在Ubuntu上运行我的应用程序时遇到任何问题。
