End Of Script Output Before Headers Python
up vote 0 down vote favorite I'm new to python, and i'm trying to run a simple script (On a Mac if that's important). Now, this code, gives me Internal Server Error: #!/usr/bin/python print 'hi' But this one works like a charm (Only extra 'print' command): #!/usr/bin/python print print 'hi' Any explanation? Thanks! Update: When I run this script from the Terminal everything is fine. But when malformed header from script python I run it from the browser: http://localhost/cgi-bin/test.py I get this error (And again, only if i'm not adding the extra print command). I use Apache server of course. python osx apache cgi share|improve this question edited Nov 19 '13 at 19:48 robertklep 75.3k9114118 asked Nov 19 '13 at 19:14 Avi Tsadok 1,506815 1 What is the exact error stacktrace ? –codegeek Nov 19 '13 at 19:19 I'm surprised you get an "internal server error" when running a simple script. I noticed the 'apache' tag but that doesn't say anything about the way you actually run your script... –Ioan Alexandru Cucu Nov 19 '13 at 19:26 HI, I updated my question. –Avi Tsadok Nov 19 '13 at 19:36 add a comment| 1 Answer 1 active oldest votes up vote 6 down vote accepted Looks like you're running your script as a CGI-script (your edit confirms that you're using CGI) ...and the initial (empty) print is required to signify the end of the headers. Check your Apache's error log (/var/log/apache2/error.log probably) to see if it says 'Premature end of script headers' (more info here). EDIT: a bit more explanation: A CGI script in Apache is responsi

Also, when I run the file from the command line it executes just fine. " So far the http://stackoverflow.com/questions/378811/getting-python-to-work-internal-server-error only change I have made to apache is to add the .py to the "AddHandler cgi-script" line. Thanks! Thanks for the quick responses. Here is the latest version of the test code. I added a couple new lines before the output as suggested but still get the same error: #!/usr/local/bin/python print "Content-type: text/html\n" print "\n\n" print "" print "

" print "" print "" Some other details: I am running Apache 1.3 and don't have mod_python. I set apache to recognize .py as mentioned above. I am running the script from the main public_html folder. An update. It doesn't seem to matter what I put in the shebang line. I tried all of the suggestions and even if I leave it blank the same error is showing up in the errors log and I'm getting a 500 error.

Try: chmod a+x foo.py (where foo.py is your script name).

The short answer: this is internal server usually a permissions error on your CGI script, which is easy to fix. Go to your FTP client, or your website file manager, and highlight or right-click on the CGI script. Then choose Properties, or Permissions, or "Chmod", and set it to world-executable: that's 0755, or a+rx, or -rwxr-xr-x. Do NOT use 0777 (a+rwx or -rwxrwxrwx). And your cgi-bin internal server error directory itself should also be 0755, not 0777. The long answer: when running a Perl CGI script like FileChucker or UserBase, you may see the "Internal Server Error" message in your browser. The message will usually also say something like "please check the server's error-log for more information." You should do that -- the message printed to the error log will often tell you exactly what the problem is. The Apache error log, for example, is often located at /var/log/apache/error_log or /var/log/apache2/error_log (or sometimes "error.log"). If you don't have access to the error log, the next simplest thing to do is to make a backup copy of the script, then open the original and delete all of its contents, and add just these 3 lines to the file: #!/usr/bin/perl print "Content-type: text/plain\n\n"; print "testing...\n"; (Note: if the server is a Windows system, then replace the first line above with either #!perl or #!c:\path\to\perl.exe.) Now try to access the page in your browser again. If it works (you see "testing..." as its output)
