如果 CGI 脚本以 #!/usr/bin/env perl 开头，则 HTTP 错误 404（未找到）

Question

I have a CGI script whose content is not important. It works fine when executed from the web, but only if the first line is

#!/usr/bin/perl -w

If I change it to

#!/usr/bin/env perl

...then I got HTTP Error 404 (Not found).

When executed from the console, the script works properly in both cases. What is wrong?

---

EDIT

I solved my problem with adding the following lines at the beginning of my script:

#!/usr/bin/env perl

use lib '/usr/local/lib64/perl5';
use lib '/usr/local/share/perl5';
use lib '/usr/lib64/perl5/vendor_perl';
use lib '/usr/share/perl5/vendor_perl';
use lib '/usr/share/perl5';
use lib '/root/perl5/lib/perl5';

Obviously there is some problem with path, which I don't understand why, because when I execute script from the console, it works even without the use of use lib .

Answer 1

I don't think the problems have anything to do with each other, or the solution actually solves anything. If Apache can't find the script, it will still not be able to find it by adding the library paths. On the other hand, if there's any problem running the script the server would return a 500 status, not a 404. In every case, it's always the best to check the logs for the exact problem.

Answer 2

Your CGI environment probably has no PATH , or doesn't have /usr/bin/ in PATH , therefore env doesn't find perl.
