Question

The first time Twiki installation on FreeBSD. The configuration utility generates the following

Error: The CGI::Session Perl module is required for session support, but is not available.

{UseClientSessions} is always on

Also /var/log/httpd-error.log shows:

[Sat Nov 04 19:02:43 2006] [error] [client xxx] Can't locate CGI/Session.pm in @INC (@INC contains: /usr/local/www/twiki/lib/CPAN/lib//arch/ /usr/local/www/twiki/lib/CPAN/lib//5.8.8/i386-freebsd-64int/ /usr/local/www/twiki/lib/CPAN/lib//5.8.8/ /usr/local/www/twiki/lib/CPAN/lib// /usr/local/www/twiki/lib . /usr/local/lib/perl5/5.8.8/BSDPAN /usr/local/lib/perl5/site_perl/5.8.8/mach /usr/local/lib/perl5/site_perl/5.8.8 /usr/local/lib/perl5/site_perl/5.8.7 /usr/local/lib/perl5/site_perl /usr/local/lib/perl5/5.8.8/mach /usr/local/lib/perl5/5.8.8) at (eval 15) line 1.

Any help appreciated.

Answer

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

That looks pretty straightforward: Install CGI::Session, or set $TWiki::cfg{UseClientSessions} to a false value.

This is my first Twiki installation and the following is what I have done so far.

What I have done wrong?

Thank you for your help.

  Current PATH  /bin:/usr/bin 
This is the actual PATH setting that will be used by Perl to run programs. It is normally identical to {SafeEnvPath}, unless that variable is empty, in which case this will be the webserver users standard path..

To install CGI::Session see HowToInstallCpanModules.

-- PeterThoeny - 07 Nov 2006

On FreeBSD you can install a port called "portupgrade" which will help with this. It's in /usr/ports/sysutils.

Once portupgrade is installed you can do;

portinstall -vR --exclude "twiki" twiki

If you're needing CPAN modules, it's better to see if it is available as a FreeBSD port before installing it directly from CPAN. It makes upgrades and management much easier.

Hi, thank you all for suggestions.

I tried to install CPAN:

... cpan shell -- CPAN exploration and modules installation (v1.7602) ReadLine support enabled

Unfortunately nothing changed and TWiki still complain that cannot find TWiki/Plugins/TablePlugin/Core.pm

Is this is due to path setting or incomplete CPAN installation?

Thank you for your help

-- TWikiGuest - 12 Nov 2006

This is where Core.pm can be found:

/usr/local/www/twiki/lib/TWiki/Plugins/EditTablePlugin/Core.pm /usr/local/www/twiki/lib/TWiki/Plugins/TablePlugin/Core.pm /usr/ports/www/twiki/work/lib/TWiki/Plugins/EditTablePlugin/Core.pm /usr/ports/www/twiki/work/lib/TWiki/Plugins/TablePlugin/Core.pm

Where should I set the path that twiki locates that module?

-- TWikiGuest - 13 Nov 2006

Oops. My mistake. I forgot to set proper permission.

It is working now; thanks for the help.

-- TWikiGuest - 13 Nov 2006

Glad it worked, closing question.
