ImportError：名前をインポートできませんNavigationToolbar2QTAgg

Question

私はPyQt4アプリケーションプロジェクトを持っています。私はWindows上で.exeに変わりたいと思います。私はcdをメインスクリプトに付けて、pyinstaller SPCanalyse.pyを実行します。私は.exeファイルを実行しようとすると私が取得：

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 

はthisを読んで、私はmatplotlib.backends.backend_qt4agg import NavigationToolbar2QTからSPCanalyse.pyの先頭になく、無駄に追加しようとしました。私は驚いていますが、彼らはそれを修正したように見えるので、私はまだエラーがあります。

私はmatplotlibバージョン1.5.1を持っていて、このバージョンではNavigationToolbar2QTAgg was removedが見つかりましたが、これは私がエラーが出る理由と関係があります。それが削除された場合、なぜ私のコードはそれをインポートしようとしますか？この試行されたインポートを防止するにはどうすればよいですか？

私はUbuntuで自分のアプリケーションを実行する際に問題がないことに注意してください。

だから私は今、このに百万回をやりました。 MatplotlibWidget.pyに違反しているラインに

C:\Python27\python.exe C:/Users/user/PycharmProjects/BMDanalyse/BMDanalyse/SPCanalyse.py

移動し、これに

from matplotlib.backends.backend_qt4agg import NavigationToolbar2QTAgg as NavigationToolbar 

を変更します：あなたはこれを見たとき

from matplotlib.backends.backend_qt4agg import NavigationToolbar2QT as NavigationToolbar 

はい、あなたは、この修正プログラムのために恒久的にバックエンドのコードを変更しています。私はこの変更を行った後、何の問題もありませんでした。 NavigationToolbar2QTAggが削除されましたmatplotlib 1.5.0
