SID-01397: CPAN is not available

Status:	Unanswered	TWiki version:	5.1.1	Perl version:	perl, v5.10.1
Category:	CategoryInstallation	Server OS:	Red Hat Enterprise Linux Server release 6.2	Last update:	13 years ago

Hi,

I have followed this http://twiki.org/cgi-bin/view/TWiki/HowToInstallCpanModules and this http://twiki.org/cgi-bin/view/Codev/TWikiOnRedHat

I tried rpm and manual methods to install CPAN

But I still get this :

Warning: CPAN is not available, some installer functions have been disabled

When I try to install plugins or extensions from the web installer.

Could anyone help ?

Thanks

Discussion and Answer

Try to resolve the dependencies first on the shell level. Use yum install ... if package is available, else follow the instructions in HowToInstallCpanModules. Once the dependencies are solved you should be able to install the plugin via the configure script. You can install plugins also manually.

Thanks Peter, but that is already done, see below :

# rpm -qa | grep -i CPAN
perl-Parse-CPAN-Meta-1.40-119.el6_1.1.x86_64 perl-CPANPLUS-0.88-119.el6_1.1.x86_64 perl-CPAN-1.9402-119.el6_1.1.x86_64
# rpm -qa | grep perl-CGI-Session
perl-CGI-Session-4.35-5.el6.noarch
# rpm -qa | grep FreezeThaw
perl-FreezeThaw-0.45-5.el6.noarch
# rpm -qa | grep gd-
gd-2.0.35-10.el6.x86_64

I have also downloaded and installed manually specific perl modules :

# cd /data/my-build
# ls

CPAN-1.9800/                       HTML-Tree-4.2/                     perl-ldap-0.44/                 Test-Exception-0.31/
Unicode-Map-0.112/              Unicode-MapUTF8-1.11/        Authen-SASL-2.15/          Digest-MD5-2.51/ Jcode-2.07/
Sub-Uplevel-0.22/                 Unicode-Map8-0.13/              Unicode-String-2.09/        Time-modules-2011.0517/

Since I want these modules to be only installed and used by twiki (outside of the global packaged system), I have installed them like this :

# cd /data/my-build/perl-modulexxx
# perl -I /data/twiki/lib/ Makefile.PL INSTALL_BASE=/data/twiki/
# make
# make install 

/data/twiki is the twiki web root

I also have added this in /data/twiki/bin/LocalLib.cfg:

 $twikiLibPath = "/data/twiki/lib";
@localPerlLibPath = ( '/data/twiki/lib, /data/twiki/lib/perl5' )

As you can see, CPAN is installed both as a whole system package and as a specific twiki library as well, but I still get this warning :

Warning: CPAN is not available, some installer functions have been disabled

and installation of an extension such as LdapContrib fails
