64bit ubuntu 12.04 python cannot run an existing python file

Question

absolute path, fails:

nan@UXN:~$ python /home/nan/google_appengine/goagent/local/proxy.py
python: can't open file '/home/nan/google_appengine/goagent/local/proxy.py': [Errno 2] No such file or directory

relative path, also fails:

nan@UXN:~$ cd /home/nan/google_appengine/goagent/local
nan@UXN:~/google_appengine/goagent/local$ python proxy.py
python: can't open file 'proxy.py': [Errno 2] No such file or directory

I have read some solutions, they say its a shared problem. and I ran：

sudo apt-get install libc6-i386 lib32gcc1 lib32z1 lib32stdc++6 ia32-libs

but still fails. What should I do? thanks.

nan@UXN:~$ ls -alhs /home/nan/google_appengine/goagent/local/

Answer 1

This is a fairly traditional permissions problem.

You should make your file executable before you try and run it. Just do chmod +x /home/nan/google_appengine/goagent/local/proxy.py. That gives this file the permission to be executable (x).

Do not run these local script using sudo if you ask me. Unless you are 100% sure they can do nothing bad to your system.

Correction

Hmm. I just read through your question again and your proxy.py already has executable permissions... So this cannot be the problem. Apologies. All suggestions welcome.
