问题
I am having trouble porting a working, Windows Python application to Linux. I am having some problems, because I did not write the code and am just learning Python. I am having trouble fixing the issues that it keeps throwing up. So here is a kind of error that right now I am stuck with
Traceback (most recent call last):
File "alpha_beta", line 237, in <module>
main()
File "alpha_beta", line 185, in main
ABCCmd()
File "alpha_beta.py", line 74, in ABCCmd
File "C:\softs\Python\Lib\shutil.py", line 80, in copy
File "C:\softs\Python\Lib\shutil.py", line 47, in copyfile
IOError: [Errno 13] Permission denied: '/myPath/XFiles.bin.addr_patched
Any pointers on how to fix it will be much appreciated
Edit:
1) What I mean by I am stuck is, the traceback of the error goes to C:\softs\Python\Lib but actually I am currently executing this code in Ubuntu. Why would the traceback reference to windows library
2) Another thing that bothers me is it says there is an IOError.But when I try to add permission for the denied one it gives me a chmod: changing permissions of /myPath/xFiles.bin.addr_patched': Operation not permitted Edit 2:
I had commented out a module because I thought it wasn't very useful. Since Now I am anyway discussing the porting issues, I thought I can bring up this additional problem as well since I think the issue is the same and the fix should be similar. On including #pdb module in the python code, I get the following error
traceback (most recent call last):
File "alpha_beta", line 6, in <module>
import pdb
File "C:\softs\Python\Lib\pdb.py", line 14, in <module>
File "C:\softs\Python\Lib\pprint.py", line 39, in <module>
ImportError: No module named cStringIO
I looked at the importer_Cache and looks like this
'': None, '/usr/lib/python2.6/plat-linux2': None, '/usr/lib/python2.6/': None
'/usr/lib/pymodules/python2.6/gtk-2.0': None, '/usr/lib/python2.6/lib-tk': None,
'/usr/lib/python2.6/lib-old': <imp.NullImporter object at 0x7f1269048070>, '/usr/

'/usr/local/lib/python2.6/dist-packages': None, '/usr/lib/python2.6/dist-packages':
None
*SOLVED : There was a weird wrapper in the script which was causing the python script to execute from a different location. Still don't understand how though. After modifying my script to just directly execute as python myScript.py it runs fine. Thank you all anyway for the help
回答1:
The mixture of Windows and Unix style paths in your error messages makes me think that you may have some filenames that are hard coded or manually created using os specific path separators ('\' or '/'). If you can figure out where the gOptions.inputTf and gWorkingTfFile values are assigned you should look into using os.path.join to help you use the correct paths.
from os.path import join
file = join('A', 'B')
# 'A/B' on unix systems
# 'A\B' on windows systems
