问题
I've got a fresh copy of PHPUnit installed on my system (Ubuntu 11), but whenever I type phpunit in the console I get the following error:
PHP Fatal error: Call to undefined method PHP_CodeCoverage_Filter::getInstance() in /usr/bin/phpunit on line 39
I have PHPUnit's code coverage installed, as far as I know:
>sudo pear install phpunit/PHP_CodeCoverage
phpunit/PHP_CodeCoverage is already installed and is the same as the released version 1.1.1
install failed
Why am I getting this error and how can I fix it?
回答1:
The executable script that loads PHPUnit must not have been updated when going to 3.6.x. Reinstall it.
sudo pear uninstall phpunit/PHPUnit
sudo pear install phpunit/PHPUnit
If this doesn't work, make sure PEAR itself is up-to-date.

Ubuntu 11.10 has had an issue for a while that hasn't been fixed. This is the only thing that will get phpunit to work with pear. (Outside of using pear you can look up a way to do it without pear. There is an article online about that but I wouldn't want that kind of burden to do it manually). This is the only thing that worked for me:
sudo apt-get remove phpunit
sudo pear channel-discover pear.phpunit.de
sudo pear channel-discover pear.symfony-project.com
sudo pear channel-discover components.ez.no
sudo pear update-channels
sudo pear upgrade-all
sudo pear install --alldeps phpunit/PHPUnit
sudo pear install --force --alldeps phpunit/PHPUnit

For some, Anthony's solution will not work fully because of the Unknown remote channel: pear.symfony.com or phpunit/PHPUnit requires package "channel://pear.symfony.com/Yaml".
SO here is the upgraded solution that solves this:
sudo apt-get remove phpunit
sudo pear channel-discover pear.phpunit.de
sudo pear channel-discover pear.symfony-project.com
sudo pear channel-discover components.ez.no
sudo pear channel-discover pear.symfony.com
sudo pear update-channels
sudo pear upgrade-all
sudo pear install pear.symfony.com/Yaml
sudo pear install --alldeps phpunit/PHPUnit
sudo pear install --force --alldeps phpunit/PHPUnit

The method getInstance() seems to have been dropped from the class.

Use the constructor instead if you come across this error. However, this is not applicable to the opening post as the command came from PHPUnit itself.
回答5:
it works for me. at the beginning, I didn't use --force for the last command, I got a fatal error that "Call to undefined method PHP_CodeCoverage_Filter::getInstance". Then I used --force, which resolved this issue.

While i had the same problem and managed to solve it using setting correct environment variables.
You can get to the solve here http://rkrants.blogspot.in/2013/01/installing-phpunitpear-in-ubuntu-1210.html
In short I had to re-install PHPUnit using pear after setting the variables correct.
I used a Ubuntu 12.10 installation and it works perfectly now.

I came across the same problem, managed to solve it using composer
Try these steps -
First uninstall phpunit
sudo apt-get remove phpunit
Install composer - http://getcomposer.org/doc/01-basic-usage.md#installation
$ curl -sS https://getcomposer.org/installer | php
Install phpunit - http://phpunit.de/manual/3.7/en/installation.html
For a system-wide installation via Composer, you can run:
$ composer global require 'phpunit/phpunit=3.7.*'
You will also have to make sure that you have ~/.composer/vendor/bin/ in your path.
