Question

“PHP模块gd：缺少”我收到了这样的错误。我正在尝试安装php5-gd。

apt-get install php5-gd

我正在使用Ubuntu 16.10和PHP版本7.我进行了所有更新。

当我尝试安装php5-gd时，我收到如下错误。

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package php5-gd is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'php5-gd' has no installation candidate

首先通过sudo php -v检查您拥有的php版本。我有php7所以结果是：

PHP 7.0.18-0ubuntu0.17.04.1 (cli) (built: Apr 26 2017 23:59:48) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
with Zend OPcache v7.0.18-0ubuntu0.17.04.1, Copyright (c) 1999-2017, by Zend Technologies

因为我有php7，我将执行以下操作来列出php包

sudo apt-cache search php7-*

此返回
