我想用 GD 转换低分辨率的图像.我正在这些规范下的 IBM 服务器上工作版本:PHP 7.0.15-0ubuntu0.16.04.4 (cli) ( NTS )
我也从 php.ini 注释掉了扩展名，但无法在 php 服务器上启用 GD.我刚收到这个错误.

and I have also comment out the extension from php.ini but can't enabled the GD on php server. I Just received this error.

运行命令: sudo apt-get install libgd

当我运行时的第二个命令给出此消息:

1) 包有未满足的依赖项

1) packages have unmet dependencies

并在运行此命令后收到:

您可能需要运行apt-get -f install"来更正这些:

You might want to run 'apt-get -f install' to correct these:

以下软件包具有未满足的依赖项:libgd-dev : 取决于: libgd3 (= 2.1.1-4ubuntu0.16.04.6) 但它不会被安装

The following packages have unmet dependencies: libgd-dev : Depends: libgd3 (= 2.1.1-4ubuntu0.16.04.6) but it is not going to be installed

E:未满足的依赖项.尝试不带软件包的apt-get -f install"(或指定解决方案).

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

此问题的原因:

PHP 致命错误:未捕获的错误:调用未定义的函数 imagecreatefromstring()

PHP Fatal error: Uncaught Error: Call to undefined function imagecreatefromstring()
