from sikuli import *. ImportError: No moude named sikuli

I am running Sikuli X 1.1.0 on Win7 Professional x64. Jython 2.7.0
I have built several test scripts which run fine in the Sikuli IDE, but do not run correctly from the command line.

Here is my code:
===========================================================================
import unittest
from sikuli import *

class TestType(unittest.TestCase):
    def testOpenText(self):
        try:
            doubleClick("C:/Sikulix1.1.1/TestKeyIn.sikuli/1487128963180.png")
            wait("C:/Sikulix1.1.1/TestKeyIn.sikuli/1487129022614.png")
        except:
            print "StartFailed"
        if exists("C:/Sikulix1.1.1/TestKeyIn.sikuli/1487129022614.png"):
            type("123456")
            sleep(1)
            type(Key.ENTER)
            sleep(1)
            type("KEVIN")
            print "OpenText_Succeeded"
            assert True
        else:
             print "OpenText_Failed"
             assert False
    def testSaveText(self):
        try:
            sleep(1)
            click("C:/Sikulix1.1.1/TestKeyIn.sikuli/1487129113840.png")
            sleep(1)
            click("C:/Sikulix1.1.1/TestKeyIn.sikuli/1487129165925.png")
            print "SaveText_Succeeded"
            assert True
        except:
            print "SaveText_Failed"
            assert False

suite = unittest.TestLoader().loadTestsFromTestCase(TestType)
unittest.TextTestRunner().run(suite)
===========================================================================

It can runs at Sikuli IDE.

But if I use windows command line:
jython test.py

I got the error msg:
Traceback <most recent call last>:
  File "test.py", line 2, in <module>
    from sikuli import *
ImportError: No module named sikuli

Could someone help me please ?
Thanks.
