推荐答案

即使有其他答案，建议安装更多不必要的软件通常也不是最佳解决方案.相反，您应该解决潜在的问题.出现这些消息的原因是因为您试图加载这些扩展名，但未安装它们.因此，简单的解决方案只是告诉PHP停止尝试加载它们:

Even though several other answers suggest it, installing more unnecessary software is generally not the best solution. Instead, you should fix the underlying problem. The reason these messages appear is because you are trying to load those extensions, but they are not installed. So the easy solution is simply to tell PHP to stop trying to load them:

首先，找出哪些文件正在尝试加载上述扩展名:

First, find out which files are trying to load the above extensions:

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

Ubuntu的示例输出:

Example output for Ubuntu:

/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，只需查找正在加载导致错误的扩展名的文件，并用;注释掉这些行.由于某种原因，默认安装的Ubuntu发生在我身上，因此希望对其他人有所帮助.

Now just find the files that are loading the extensions that are causing the errors and comment out those lines with a ;. For some reason this happened to me with the default install of Ubuntu, so hopefully this helps someone else.
