yum install php dependency errors

Question

I'm trying to install php 5.4 or 5.6 on an Amazon Linux 2 server using this command:

yum install php54

This is the output:

Loaded plugins: extras_suggestions, langpacks, priorities, update-motd

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

The output suggests that it knows which packages contain the dependencies that the errors mention, yet it doesn't install them.

I've previously installed the epel and remi repositories, since amazon-linux-extras does not have php version lower than 7.1.

When I execute:

yum list installed | grep "php"

I get not results, so I don't think there's a conflict with existing packages.

I also tried:

yum install php54 --disablerepo="*" --enablerepo="remi"

to make sure that there are no repository conflicts.

EDIT: I've also tried other versions of the command:

yum install php70
yum install php71
yum install php72

And they all had similar errors regarding the same "lib*" requirements.

Any idea why this is happening and how to fix this?

Answer 1

I removed an amazon repo that was needed to find the lib* dependencies when I was troubleshooting and forcing yum to select the remi repo. After adding it back in, the command worked.

However, now I have to figure out how to configure php, as those packages didn't create a php.ini file that was deleted when I uninstalled amazon's php7.1.
