尽管有其他几个答案建议这样做，但安装更多不必要的软件通常不是最好的解决方案。相反，您应该解决根本问题。出现这些消息的原因是您尝试加载这些扩展，但未安装它们。所以简单的解决方案就是告诉 PHP 停止尝试加载它们:

首先，找出哪些文件正在尝试加载上述扩展:

$ grep -Hrv ";" /etc/php5 | grep -E "extension(\s+)?="

Ubuntu 的示例输出:

/etc/php5/mods-available/gd.ini:extension=gd.so
/etc/php5/mods-available/pdo_sqlite.ini:extension=pdo_sqlite.so
/etc/php5/mods-available/pdo.ini:extension=pdo.so
/etc/php5/mods-available/pdo_mysql.ini:extension=pdo_mysql.so
/etc/php5/mods-available/mysqli.ini:extension=mysqli.so
/etc/php5/mods-available/mysql.ini:extension=mysql.so
/etc/php5/mods-available/curl.ini:extension=curl.so
/etc/php5/mods-available/sqlite3.ini:extension=sqlite3.so
/etc/php5/conf.d/mcrypt.ini:extension=mcrypt.so
/etc/php5/conf.d/imagick.ini:extension=imagick.so
/etc/php5/apache2/php.ini:extension=http.so

现在只需找到正在加载导致错误的扩展的文件并使用 ; 注释掉这些行。由于某种原因，默认安装的 Ubuntu 发生在我身上，所以希望这对其他人有帮助。
