Actually I tried to use dbgpavim to debug a python program on linux. So I typed in sudo ./pydbgp -d 127.0.0.1:9009 ~/myProjectj/main.py on linux but I got an error message "dbgpSocket: error: unable to connect to remote host at 127.0.0.1:9009". Here pydbgp is installed in current directory and main.py is my python program. I also entered "let gbgPavimPort = 9009" and "let gbgPavimBreakAtEntry = 0" in file ~/.vimrc. Does any python guru know what might be the problem? Thank you very much!
