eclipse - RuntimeError for SDL2 after installing pySDL2 -

i installed pysdl2 0.4.1 by:

downloading source package, entering python setup.py install. tried run copypasted pydev eclipse "the pong game: getting started" tutorial code example:

import os, sys

try:     os.environ["pysdl2_dll_path"] = "/home/me/workspace/pong/third-party"     print(os.getenv("pysdl2_dll_path"))     sdl2 import events, sdl_quit     import sdl2.ext sdl2ext except importerror:     import traceback     traceback.print_exc()     sys.exit(1)  def run():     sdl2ext.init()     window = sdl2ext.window("the pong game", size=(800, 600))     window.show()     running = true     while running:         events = sdl2ext.get_events()         event in events:             if event.type == sdl_quit:                 running = false                 break         window.refresh()     return 0  if __name__ == "__main__":     sys.exit(run()) 

i got following error:

traceback (most recent call last):   file "/home/me/workspace/pong/main.py", line 11, in <module>     sdl2 import *   file "/usr/local/lib/python3.3/dist-packages/sdl2/__init__.py", line 2, in <module>     .dll import get_dll_file, _bind   file "/usr/local/lib/python3.3/dist-packages/sdl2/dll.py", line 90, in <module>     dll = _dll("sdl2", ["sdl2", "sdl2-2.0"], os.getenv("pysdl2_dll_path"))   file "/usr/local/lib/python3.3/dist-packages/sdl2/dll.py", line 51, in __init__     raise runtimeerror("could not find library %s" % libinfo) runtimeerror: not find library sdl2 

i have both pypy , libsdl installed via synaptic , have no external libraries added in pydev - pythonpath.

what doing wrong?

it seems pysdl2 doesn't find sdl2 runtime library. available on libsdl download page (except linux).

you should let pysdl2 library setting pysdl2_dll_path so:

# win32 platforms set pysdl2_dll_path=c:\path\to\fancy_project\third_party  # unix/posix-alike environments - bourne shells export pysdl2_dll_path=/path/to/fancy_project/third_party  # unix/posix-alike environments - c shells setenv pysdl2_dll_path /path/to/fancy_project/third_party 

or in python script:

# win32 platform path os.environ["pysdl2_dll_path"] = "c:\\path\\to\\fancy_project\\third_party" # unix/posix-alike environments path os.environ["pysdl2_dll_path"] = "/path/to/fancy_project/third_party" 

that way, pysdl2 find library files (as long path correct of course) ! seems me easier way.

happy coding sdl2 !
