Python CGI Script: OSError: [Errno 8] Exec format error
cgi, python
Solution
The solution in this case was that I was using the wrong version of Python to run the script. The default in osx 10.9 is Python 2.7.5. I wanted to run it with python 3.3, therefore my solution was simply to execute it with the appropriate version: `#!/usr/local/bin/python3`
Problem
When I send `http://localhost:8888/cgi-bin/peoplecgi.py?action=Fetch&key=sue` (sue is a valid key in the shelve) to the cgi script below I get the following (also I'm on OSX with Python 3.3). Any ideas what is going wrong? ``` 127.0.0.1 - - [04/Feb/2014 10:38:41] "GET /cgi-bin/peoplecgi.py?action=Fetch&key=sue HTTP/1.1" 200 - Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/http/server.py", line 1131, in run_cgi os.execve(scriptfile, args, env) OSError: [Errno 8] Exec format error: '/Users/rich/Google Drive/Code/Python/PP4E/Preview/cgi-bin/peoplecgi.py' 127.0.0.1 - - [04/Feb/2014 10:38:41] CGI script exit status 0x7f00 ``` I am working out of O'Reilly's Programming Python 4th Edition.
