I had the same problem. Was solved by reinstalling the pyinstaller with the developer's branch version, following the directions in: https://github.com/pyinstaller/pyinstaller/issues/2137

from kivy_deps import sdl2, glew
import pkg_resources.py2_warn # before you add it to hiddenimports, import it here.
import dependency_injector.errors
import six
block_cipher = None


a = Analysis(['...'],
             pathex=['..'],
             binaries=[],
             datas=[],
             hiddenimports=['pkg_resources.py2_warn', 'dependency_injector.errors', 'six'], # This is the line you need
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='...',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe,
                Tree('./'),
               a.binaries,
               a.zipfiles,
               a.datas,
               *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
               strip=False,
               upx=True,
               upx_exclude=[],
               name='...')

Whenever you encounter an import error, just import them at the top and add them as a string to hiddenimports in the array.
