我正在尝试通过以下命令在我的 Ubuntu 12.04 机器上安装 Gearman
sudo apt-get install gearman-job-server libgearman-dev
sudo apt-get install php-pear php5-dev
以上命令运行正常，但是当我运行时
sudo pecl install gearman
它给出的错误如下
checking whether to enable gearman support... yes, shared
found in /usr
checking for gearman_client_set_context in -lgearman... yes
checking for gearman_worker_set_server_option in -lgearman... yes
checking for gearman_job_error in -lgearman... no
configure: error: libgearman version 1.1.0 or later required
ERROR: `/tmp/pear/temp/gearman/configure' failed
我找不到如何安装它。
