python - RuntimeError: could not find any library for SDL2_ttf

Question

I have a problem with pysdl2. I'm trying to launch examples from site-packages\sdl2\examples and see this error:

c:\Python33\Lib\site-packages\sdl2\examples>python draw.py
Traceback (most recent call last):
  File "draw.py", line 10, in <module>
    import sdl2.ext as sdl2ext
  File "C:\Python33\lib\site-packages\sdl2\ext\__init__.py", line 14, in <module>
        from .common import *
  File "C:\Python33\lib\site-packages\sdl2\ext\common.py", line 8, in <module>
    from .. import sdlttf
  File "C:\Python33\lib\site-packages\sdl2\sdlttf.py", line 40, in <module>
    os.getenv("PYSDL2_DLL_PATH"))
  File "C:\Python33\lib\site-packages\sdl2\dll.py", line 51, in __init__
    raise RuntimeError("could not find any library for %s" % libinfo)
RuntimeError: could not find any library for SDL2_ttf

But files which don't use sdl2_ttf (such as sdl2hello.py) work correctly and without errors. I have no idea how to solve it.
