10.2: ImportError with other script in same folder --- sys.path has to contain each script folder, that you want to import

might be, that this is because C:\Program Files\ needs special access rights and it is not writeable for everyone.

When importing a some_name.py file from some_name.sikuli in Jython (means Sikuli IDE), Jython writes a some_name$py.class file to that directory. this write operation might make problems deep down inside and comes to the surface as "No module ..." error.

So I suggest to put your files in a directory, that you have full access to (e.g. C:\Sikuli_Modules\ ) and put your .sikuli stuff there.

I moved my two Sikuli's scripts in C:\NonReg to avoid this kind of issue but it's not working.
I get the same message :
"[sikuli] Error message:
Traceback (most recent call last):
  File "C:\DOCUME~1\LOCALS~1\Temp\sikuli-tmp5123543583718084860.py", line 1, in <module>
  import VPsLogin
ImportError: No module named VPsLogin"

I tested also with 'from VPsLogin import *' and 'import VPsLogin' but always the same error

I've added at the top main.sikuli these lines :
myScriptPath="C:\\NonReg\\VPsLogin.sikuli"
if not myScriptPath in sys.path: sys.path.append(myScriptPath)

And now it works fine !

Thanks for your help RainMan

---1. If the main script and the imported scripts (all as .sikuli) are in the same folder and running the main script, the import should find the stuff to import.

So if you have:
# c:\NonReg\main.sikuli
import sub

and
# c:\NonReg\sub.sikuli
from sikuli import *

running main in Sikuli IDE should give no error

---2. sys.path
In sys.path you need only the folder that contains the .sikuli scripts and not the scripts itself.

your case:
myScriptPath=r"C:\NonReg" # raw string r"no double \ needed"
if not myScriptPath in sys.path: sys.path.append(myScriptPath)

In my case it doesn't work.
I tested :
# c:\NonReg\main.sikuli
myScriptPath=r"C:\NonReg"
if not myScriptPath in sys.path: sys.path.append(myScriptPath)
import sub

# c:\NonReg\sub.sikuli
from sikuli import *

and I have always the same issue "ImportError: No module named VPsLogin"

It's working only if I have :
# c:\NonReg\main.sikuli
myScriptPath=r"C:\NonReg\sub.sikuli"
if not myScriptPath in sys.path: sys.path.append(myScriptPath)
import sub

# c:\NonReg\sub.sikuli
from sikuli.Sikuli import *

That's really weird but if I'm able to work in this way, it doesn't matter for me

Please, do me a favor and run the following test script after saving it to the c:\NonReg folder as main.sikuli:

print "***** before import"
for e in sys.path: print e
okImport = False

try:
    import subNotExists
    okImport = True
except:
    print "***** after import not ok"
    for e in sys.path: print e

if okImport:
    print "***** after import ok"
    for e in sys.path: print e

... and paste the content of the message area here, please.

Here are the content of the message area :

I just realized, that I never asked:
What version of Sikuli are you using?

Does not seem to be the latest version or even rc3?

I'm using 0.10.2

Uuuups, I already doubted that ;-)

10.2 does not have the import support for .sikuli scripts, that is only available in X-1.0rc3.
In 10.2 you have to do it as you found out already.

Any reason for using 10.2 instead of X?

X is much faster and has more features.

One more thing:

10.2 import does not make available the images, that are captured in the imported scripts.

All images have either be referenced with absolute path or be in the main script (where bundlePath points to)

OK RaiMan.
So I install Sikuli X rc3 (https://launchpad.net/sikuli/+milestone/x1.0-rc3)
So now, my first test with main and sub in C:\Program Files\Sikuli
#main.sikuli:
print "***** before import"
for e in sys.path: print e
okImport = False

try:
    import subNotExists
    okImport = True
except:
    print "***** after import not ok"
    for e in sys.path: print e

if okImport:
    print "***** after import ok"
    for e in sys.path: print e

#sub.sikuli
from sikuli import *

I made a brand new install of Sikuli X and all exceptions are gone.
main.sikuli and sub.sikuli are in the same folder (c:\NonReg)

So I ran the main.sikuli :
print "***** before import"
for e in sys.path: print e
okImport = False

try:
    import subNotExists
    okImport = True
except:
    print "***** after import not ok"
    for e in sys.path: print e

if okImport:
    print "***** after import ok"
    for e in sys.path: print e

Here is my message area :

I made a new test with the x release :
main.sikuli :
myScriptPath=r"C:\NonReg"
if not myScriptPath in sys.path:sys.path.append(myScriptPath)
import VPsLogin
VPsLogin.sub1()
....

VPsLogin.sikuli :
from sikuli import *
def sub1(self):
....

And it works !!
So it was clearly a release issue.
Thanks a lot for your time and your help RaiMan !!!

BTW: def sub1(self):
does not make sense if you do not have self defined classes with methods.
So it should be:
def sub1():

So this should give you a runtime error in main like:
sub1 needs 1 parameter 0 given

Indeed, it's just a copy/paste issue ;)
