I agreed to everything it asked me, and everything turned out fine. It will prompt you a few times about dependencies. This will spend a long time downloading, testing, and compiling various files and dependencies. $ sudo perl -MCPAN -e 'install Bundle::CPAN'ĭon’t forget the sudo, or it’ll fail with permissions errors, probably when doing something relatively unimportant like installing man files. If you skip Step 2, you may get errors about make being unavailable.
If you use a proxy or a very restrictive firewall, you may have to configure those settings as well. The two things you must fill in are the path to make (which should be /usr/bin/make or the value returned when you run which make from the command line) and your choice of CPAN mirrors (which you actually choose don’t really matter, but it won’t let you finish until you select at least one). You can accept the defaults for almost everything (just hit “return”). If you like, you can run which make again to confirm that everything’s installed correctly.
#INSTALL PERL MODULES INSTALL#
Click to install the Command Line Tools.Launch XCode and bring up the Preferences panel.If you just get a new prompt and no output, you’ll need to install the tools: If it spits out something like /usr/bin/make you’re golden and can skip ahead to Step 2. This command checks the system for the “ make” tool. To check whether you have the command line tools already installed, run the following from the Terminal: Older versions of XCode installed the command line tools (which are required to properly install CPAN modules) by default, but apparently newer ones do not. (Thank you to Tom Marchioro for informing me about this step.) 1.5) Install Command Line Tools (Recent XCode versions only) If you don’t have this stuff installed, your installation will fail with errors about unavailable commands. I thought I had them, but apparently when we upgraded that computer to Tiger, they went missing. These are on one of your install discs, or available as a huge but free download from the Apple Developer Connection or the Mac App Store.
#INSTALL PERL MODULES HOW TO#
So, with a script that called on several apparently unavailable modules, and a deadline looming, I finally decided to suck it up and figure out how to use CPAN to install them: 1) Make sure you have the Apple Developer Tools (XCode) installed. Moreover, Fink doesn’t seem to make every module available, and it’s not very easy to determine which Fink package you need to install if you need a particular module.
#INSTALL PERL MODULES FULL#
The only instructions I could find point to Fink, which basically installs modules in a path that isn’t included in the Perl variable, meaning you have to manually specify the full path to the modules in every script - which is not a lot of fun if you’re developing on OS X and deploying on Red Hat, for instance. You see, for the past couple of years, I’ve been a bit frustrated because OS X does not come with a whole lot of Perl modules pre-installed, and for all I googled, I couldn’t find an “idiot’s” guide for moderately-savvy-but-not-expert users like myself to install modules and dependencies on demand. Today at work, I learned how to install Perl modules using CPAN.
