Pear telling me to upgrade and then "Nothing to upgrade"

I'm trying to install PHPUnit. I'm getting an error message that I need to update the version of Pear, but then when I try to do it, it says Nothing to update.

Any ideas what's happening here?

UPDATE - this is the output on `pear list`

I had the same problem and in my case it was because phpunit has a dependency of the pear.symfony.com channel. The following worked for me:

pear uninstall phpunit
pear channel-discover pear.phpunit.de
pear channel-discover pear.symfony.com
pear install phpunit/phpunit

Without the symfony channel, pear did only install in version 3.5.15. After adding the channel, i got 3.7.7.

First, clear the cache. Stale package information may be in there.

$ pear clear-cache
$ pear upgrade pear

Then, verify you get the correct remote package information - it should show 1.9.2:

$ pear remote-info pear
Latest      1.9.2
Installed   1.9.1
...

If the latest is not 1.9.2, you've got strange network problems. If the "installed" is listed as 1.9.2., your installation is strange :)

Verify that the PEAR version you are using is the same you are trying to upgrade:

$ which pear
/usr/bin/pear
$ pear list pear|grep bin
script /usr/bin/pear
script /usr/bin/peardev
script /usr/bin/pecl

If they do not match, fix your include path to include the correct pear version, or the pear configuration by using

$ pear config-show
$ pear config-get bin_dir
$ pear config-set bin_dir /path/to/my/bin

and force-upgrade to install the files to the correct locations:

$ pear upgrade -f pear
