shebang line not working

问题

Don't know what's wrong with my shebang line:

vic@ubuntu:~/Desktop$ ./test.py 
: No such file or directory

vic@ubuntu:~/Desktop$ ls -l
...
-rwxr-xr-x  1 vic vic        35 2011-11-06 15:46 test.py
...

vic@ubuntu:~/Desktop$ cat test.py 
#!/usr/bin/env python
print('!')

vic@ubuntu:~/Desktop$ /usr/bin/env python
Python 2.7.2+ (default, Oct  4 2011, 20:06:09) 
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 

Any ideas?

vic@ubuntu:~/Desktop$ head -n 2 test.py|hexdump -C

Your file has Windows-type line endings. Convert it to proper Unix-type line endings and you should be good to go.

$ dos2unix test.py
