Pear Upgrade Installer

I was trying to install PHPUnit today, but the box wouldn’t allow me because the Pear Installer version wasn’t current. But there was no obvious way to upgrade the pear installer.

[root@ci /]# pear install phpunit/PHPUnit
Did not download optional dependencies: pear/Image_GraphViz, pear/Log, channel://pear.symfony-project.com/YAML, use --alldeps to download automatically
phpunit/PHPUnit requires PEAR Installer (version >= 1.8.1), installed version is 1.4.9
phpunit/PHPUnit can optionally use package "pear/Image_GraphViz" (version >= 1.2.1)
phpunit/PHPUnit can optionally use package "pear/Log"
phpunit/PHPUnit can optionally use package "channel://pear.symfony-project.com/YAML" (version >= 1.0.2)
phpunit/PHPUnit can optionally use PHP extension "json"
phpunit/PHPUnit can optionally use PHP extension "xdebug" (version >= 2.0.5)
No valid packages found
install failed

The trick is to install the PEAR package with –force to make it go through

[root@ci /]# pear upgrade --force PEAR
warning: pear/PEAR dependency package "pear/Archive_Tar" installed version 1.3.6 is not the recommended version 1.3.3

From there, you can continue on the the PHPUnit Install
