Is there any helpfull information?

Answer 1

Had the same problem. In the end I was able to fix the problem by deleting my old interpreter in Preferences > PyDev > Interpreters, and creating a new interpreter called "python" which had the correct paths. After quitting and reopening eclipse, pydev found all my modules.

Answer 2

Probably your PYTHONPATH is not set properly (or if those are libraries in the interpreter, maybe you added them after configuring it).

See: http://pydev.org/manual_101_interpreter.html for references (note the part on forced builtins there as it might be your case).

Answer 3

You get an unresolved import if the required module cannot be found. Modules are searched for in the current working directory and the directories listed in sys.path. Your python cannot find the modules pycassa and tweepy it appears.
