Ubuntu无法安装PHPUnit

[damonfutan]

我是按照下面的步骤安装的

代码： 全选

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

执行到 sudo pear install --alldeps phpunit/PHPUnit 命令时出现下面的错误

代码： 全选

futan@futan-Aspire-V5-471G:/build$ sudo pear install --alldeps phpunit/PHPUnit
