PECL yaml in PHP7

Question

Having some issues with pecl yaml in PHP7 (see below for error log). What I can see on: https://pecl.php.net/package/yaml is that there's some RC's for 2.0 that is suppose to cover the issue... I'm currently running the command:

pecl install yaml && echo "extension=yaml.so" > /usr/local/etc/php/conf.d/ext-yaml.ini. 

But guess this won't install the RC version. How do I install the RC? is there a parameter to supply maybe..?

I could google the following solution (not tested):

pear config-set preferred_state beta

But I guess that this will set a global beta state for all extensions. I only want to install this extension as beta..

Answer 1

So after some additional googling I found how to install by searching for how to install beta packages, instead of RC's as I first was looking for.. face-palm

http://php.net/manual/en/install.pecl.pear.php

..so the correct command would be:

pecl install yaml-beta && echo "extension=yaml.so" > /usr/local/etc/php/conf.d/ext-yaml.ini

Stable 2.0.0 was released 2016-09-24. Version 1.x.x is still supported, so you need to specify the version number, eg:

pecl install yaml-2.0.0 && echo "extension=yaml.so" > /usr/local/etc/php/conf.d/ext-yaml.ini

Find latest release at https://pecl.php.net/package/yaml

Do you mean >> not >? – Lablab

@ShaunF One or the other, don't matter in this context. The file don't exist and you need to create it. If you like to use ">>" it will accomplish the same in this context. – Osis

I had solved this with yaml-beta earlier (and upvoted the answer), but recently I got the error again, and it was fixed with yaml-2.0.0 (as in the edited answer) – Deprived

Answer 2

On ubuntu 16.04 (PHP 7.0), you can do this :

apt install libyaml-dev php-dev php-pear
pecl install yaml-2.0.0
echo "extension=yaml.so" > /etc/php/7.0/cli/conf.d/20-yaml.ini
echo "extension=yaml.so" > /etc/php/7.0/apache2/conf.d/20-yaml.ini

• php-pear is needed to use the pecl command
• php-dev is needed for the phpize command (used by pecl)
• libyaml-dev is needed for... the yaml library

I was using pecl install yaml and I just changed to pecl install yaml-2.0.0 and it worked, thanks – Annalist

... but my php says yaml functions are not available, the phpinfo doesnt show any yaml extension... – Annalist

ok, found the reason why... there was no conf.d file added to the appropriate folder... follow these instructions if you are in the same situation as I am: forum.phalconphp.com/discussion/13753/config-yaml-in-php-7 – Annalist

Answer 3

so far so good the answer wasn't working on my Centos 7 PHP 7.

but I figure how to do it :

yum install php70w-devel php70w-pear zlib-devel curl-devel gcc
yum install libyaml-devel
pecl install yaml-beta

I hope that will help others using Centos too.

can someone please help with similar problem but in Debian? – Annalist
