Pyinstaller + Django = No module named 'django.core.context_processors'
Question: I am trying to package my django app with pyinstaller and I created this
pyinstaller spec file for this purpose:

    
    
    # -*- mode: python -*-
    
    block_cipher = None
    
    
    a = Analysis(['manage.py'],
                 pathex=['/home/gero/PycharmProjects/gen-optimizer-precision'],
                 binaries=None,
                 datas=None,
                 hiddenimports=[],
                 hookspath=None,
                 runtime_hooks=None,
                 excludes=['matplotlib'],
                 win_no_prefer_redirects=None,
                 win_private_assemblies=None,
                 cipher=block_cipher)
    pyz = PYZ(a.pure, a.zipped_data,
                 cipher=block_cipher)
    exe = EXE(pyz,
              a.scripts,
              exclude_binaries=True,
              name='optimizer',
              debug=True,
              strip=None,
              upx=True,
              console=True )
    coll = COLLECT(exe,
                   a.binaries,
                   a.zipfiles,
                   a.datas,
                   strip=None,
                   upx=True,
                   name='optimizer')
    

Here is the pyinstallers log:

Any clues fellows?


Answer: From [docs](https://docs.djangoproject.com/en/1.8/ref/templates/api/):

Probably you are importing context_processors using the old path in
`~/PycharmProjects/gen-optimizer-precision/optimizer/views.py`.
