Here you can see a warning that the freeradius Not all modules are compatible with all other modules. Next, you can see a confirmation for enabling the Perl 5. And, finally, there is another warning about installed packages. The last warning means that the system still can have installed RPM packages from the 5.
Changing modules and changing packages are two separate phases. You can fix it by synchronizing a distribution content like this:.
It works. No scl enable incantation is needed, in contrast to the software collections. A future YUM update is going to clean up the unnecessary warning.
Despite that, I can show you that other Perl-ish modules are compatible with any Perl stream. Yum can search in a packaged CPAN module, so give a try:.
Thus, yum asked for enabling the streams and installing the packages. Notice that perl These two modules have no other streams. In general, any module can have multiple streams.
At most, one stream of a module can be the default one. And, at most, one stream of a module can be enabled. An enabled stream takes precedence over a default one. If there is no enabled or a default stream, content of the module is unavailable. Enough theory, back to some productive work. Let's create a test database, a foo table inside with one textual column called bar , and let's store a row with Hello text there:.
The above set of commands downloads and installs the perl module locally. However, you still need to add this module to the perl environmental variables to let perl know where to look for the package.
So how do we do this? If you are looking for more information about environmental variables in general, here is another blogpost link here explaining these terms and why they are important. Here are some perl-related environment variables that you might need or run into:.
You may also want to explicitly unset these variables. This is especially true in cases where you want to share the code you install with others.
This is useful for setting up your own perl dependencies, but I find that installing manually and adding the files to PERL5LIB path is best for software packages that need to be widely shared. So to fix the above-mentioned error in the above section , first, you should install the perl module from source and then add the modules to the environmental variable — PERL5LIB.
To do this run the below command. To add the above-mentioned path permanently to the environmental variable, you can add this line to your. The paths are reset every time you log out and log back in. If you have to stick your hands elbow-deep into the guts of a perl program, I would start by placing this at the top:.
Then, find the line that the error is happening on, and start dumping out variables around it. To print the contents of a variable, stick this line into the code:.
Some things will be more complex than this; before learning perl in-depth or spending a week debugging a program, we would recommend contacting the software developers or placing an issue on the project if it is on Github!

That doesn't tell you where Perl is looking for the file, though. For Windows, might need to use double-quotes on the outside, single quotes on the inside.
