为PHP 5.5.9安装旧版本的Yaml（1.3.1）

Question

I tried to install yaml by using this commands

 sudo apt-get install php-pear libyaml-dev
 sudo pecl install yaml

But this YAML requires php7.0 and newer version. I use PHP 5.5.9 How can install older version of YAML.

Answer 1

You should change your package repository (For example in Debian/Ubuntu Aptitude repositories), for PHP5 versions and then install that version or YAML.

You can use also Composer for the dependencies management, or the "hardest" way, download the source code and implement by yourself.

echo "deb http://packages.dotdeb.org wheezy-php56 all" >> /etc/apt/sources.list.d/dotdeb.list
echo "deb-src http://packages.dotdeb.org wheezy-php56 all" >> /etc/apt/sources.list.d/dotdeb.list


wget http://www.dotdeb.org/dotdeb.gpg -O- |apt-key add -

apt-get update
apt-get install php-pearl ....
