Answer 1

安装是一回事.启用是另一个.请确保您的/etc/php.ini文件包含以下行:

extension=mcrypt.so

如果找不到php.ini,请创建一个test.php包含以下内容的文件:

<?php phpinfo(); ?>

执行它php test.php | grep ".ini",你会找到你的ini文件的路径.其中一个必须包括extension=上面的行.

Answer 2

您可能必须启用该模块.在Ubuntu系统上,最简单的方法是将您ini附带的文件链接php5-mcrypt到您conf.d想要使用的每个PHP二进制文件中:

sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/cli/conf.d/mcrypt.ini
sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/cgi/conf.d/mcrypt.ini
