PHP Error Installing Imagick on CentOS7 – Fix

centos7linuxpeclPHP

System – CentOS 7.5.1804

PHP Version – 7.0.3

So, I'm trying to install Imagick in order to be able to render/make an image off the first page of a PDF.

I'm tried to understand how it is setup, but I'm missing something, so I'll reproduce what I've and what I've got so far:

After a long list of errors, I got down to these 4 instalations:

sudo rpm -Uvh ImageMagick-7.0.8-9.x86_64.rpm
sudo rpm -Uvh ImageMagick-libs-7.0.8-9.x86_64.rpm 
sudo yum install php70-php-pecl-imagick.x86_64
sudo php go-pear.phar

When I'm trying to run this: sudo /usr/bin/pecl install imagick, it's giving me the following error:

WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
downloading imagick-3.4.3.tgz …

The php-devel package is required for use of this command.
ERROR: `phpize' failed

So, after checking that 'php-devel' is somewhat not here, I try to install it and I get this:

What am I doing wrong/what am I missing?

You've mixed a whole bunch of manually downloaded RPMs (some built for the wrong versions of PHP, Imagick or other things) and conflicting repositories. Stop now. Don't manually download RPMs.

You've done well to use Remi's PHP repositories, but you've enabled his repo for PHP 5.6, while you say you want PHP 7.0. You need to disable the remi-php56 repo and enable the remi-php71 or remi-php72 repo (7.0 is EOL, don't use it).

After getting the correct repo enabled, use yum distro-sync to replace all the wrong versions of packages with correct versions of packages. You'll also need to remove some packages you got from SCL or other repos, such as those with names starting with php70-.

Finally, you can get to installing the package you were looking for:
