View Full Version : Installing URI::Escape using cpan

I'm trying to install URI::Escape on a linux system in order to use uri_escape and am coming a cropper. I've never really got the hang of cpan and I don't fully understand perl modules, so I'm probably doing something stupid. Could someone help, please?
server:/home/max# cpan URI::Escape
CPAN: Storable loaded ok
Going to read /root/.cpan/Metadata
Database was generated on Sun, 09 Oct 2005 22:42:30 GMT
Running install for module URI::Escape
The module URI::Escape isn't available on CPAN.
Either the module has not yet been uploaded to CPAN, or it is
temporary unavailable. Please contact the author to find out
more about the status. Try 'i URI::Escape'.
Thanks,
Max

Isn't it installed by default? If not, I'm pretty sure your distribution
has a package for this.

perl -MURI::Escape -e 1
Can't locate URI/Escape.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.8.4 /usr/local/share/perl/5.8.4 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.8 /usr/share/perl/5.8 /usr/local/lib/site_perl .).
BEGIN failed--compilation aborted.
Thanks for the tip on packages, libcgi-perl includes it. However, the original question still stands. How would I install it with CPAN?

I think that module is part of LWP , isn't it?

What does that mean? I'm very new to Perl, so feel free to talk slowly and loudly! I thought I could use cpan to install any module that they had. Is this not the case?
Max

http://search.cpan.org/search?module=URI::Escape
Max - you can use CPAN to install directly. Some modules depend on other modules when intalling, and as such are requested for inclusion during the install (eg. the LWP module depends on URI::Escape).
You can simply run CPAN and install the module you want.
First, be sure it does not yet exist. As root, enter CPAN interactively. Then, enter the
i URI::Escape
command to see info about the module. If the module is installed, the last two lines of the output will be: something like:
INST_FILE /usr/local/lib/perl5/site_perl/5.8.5/URI/Escape.pm
INST_VERSION 3.28
This is the location and version of your module. If it does exist on your system, and you're not finding it, then you likely have a permissions problem in that it was installed with root permissions, but not group-other permissions. A change or permissions on all the files included with URI::Escape will solve the problem.
If the module is not installed, as root and with a umask of 022, install the module.
su - root
umask 022
cpan
install URI::Escape

Type this is in as root:
perl -MCPAN -e shell
That'll give you the CPAN prompt. From there, type in:
install LWP
And answer any questions it asks about dependencies and such. That's
it :)

Have a look at my original posts in this thread. It wasn't installed, and cpan install URI::Escape failed - all the logs are in the posts. I had this last time I tried to use cpan to install something, but on a completely different server. I'm guessing I'm doing something stupid.
Thanks,

But how should I know to install LWP rather than URI::Escape?
Max
Type this is in as root:
perl -MCPAN -e shell
That'll give you the CPAN prompt. From there, type in:
install LWP

You don't without experience, and the advice was a little misguided. LWP is yet another module that's commonly used. Just install the module that you want.

Look at the URL I sent you: http://search.cpan.org/search?
module=URI::Escape
You can search that site for module info.
But in general, you don't need to do that. In 99% of the time, the
CPAN installer is smart enough to know when a module is a subset of
some package and install that whole package.

I read the posts completely and understood the problem. You error only indicated the module could not be found in the INC path, not that it didn't exist. Unfortunately, the error message for uninstalled module and incorrectly installed module is exactly the same. So, you have to determine which problem it is.

The error message when I tried to use cpan implied that the module simply wasn't in cpan:
---
The module URI::Escape isn't available on CPAN.
Either the module has not yet been uploaded to CPAN, or it is
temporary unavailable. Please contact the author to find out
more about the status. Try 'i URI::Escape'.
---
But 'i URI::Escape' listed it quite happily. This is the bit that I don't understand. Needless to say, attempts to use the module failed with a compilation error.

Unfortunately, the error message for uninstalled module and incorrectly installed module is exactly the same. So, you have to determine which problem it is.
Why you weren't able to find the module that instant is a mystery. Its there.
Here's the deal. CPAN is simply as set of perl modules that helps download and install other perl modules. its also a database that tracks their version numbers and dependencies.
Your CPAN module is having trouble running, because it is currently requiring the very module you cannot find (URI::Escape).
The question is - why is that module missing / inacessible on your system? What we have not established is which of these is the problem - is it missing, or is it inaccessible?
As root, use the find command to verify this:
find / -name Escape.pm -ls
and see what comes back. This will give you all the Escape.pm files found, and their permissions. If it is found, and the permissions are restrictive, you know the problem. If it is not found anywhere, you can manually install by downloading the software in some directory, unpacking it, and running
su - ; umask 022; perl Makefile.pl; make; make test; make install

FYI - we include URI::Escape in the CPAN/ directory.

I know, this is non-slim related Perl. It's all part of learning Perl for Slim's benefit though. ;-)
