F2PY返回ValueError：無效版本號'4'。

Question

我是Python的新手，希望能夠使用我現有的Fortran代碼並從Python運行它。我正在嘗試使用F2PY編譯一個小型的「Hello world」Fortran程序，方法是按照在線說明進行操作。

我正在使用Windows。到目前爲止，我已經安裝了Python 2.7.3，NumPy 1.6.1，SciPy 10.1和MinGW 4.8。

然後，我嘗試（除其他事項外）

f2py.py -c --compiler=mingw32 --fcompiler=gnu95 -m foo foo.f90 

此報告無效的版本號。

ValueError: invalid version number '4.'

如果任何人可以建議什麼是錯的，我需要改變這個來運行，我將非常感激。 F2PY的全部輸出如下：

mingw32的distutils插件使用不兼容的版本字符串。在的distutils/version.py，線100，版本字符串匹配正則表達式是

r'^(\d+) \. (\d+) (\. (\d+))? ([ab](\d+))?$' 

編輯文件mingw32ccompiler.py手動和變更線127閱讀

elif self.gcc_version < "4.0":
