无法安装 php5-mysql 或 php5-mysqlnd

  • 772

我在 docker container 中使用 Debian Jessie docker run --entrypoint /bin/bash -i -t php:5-apache。不幸的是，我无法安装 php5-mysql 或 php5-mysqlnd 。我做了以下步骤：

apt-get update

Hit http://security.debian.org jessie/updates InRelease

Package php5-mysql is a virtual package provided by:
  php5-mysqlnd 5.6.33+dfsg-0+deb8u1 [Not candidate version]
  php5-mysqlnd 5.6.30+dfsg-0+deb8u1 [Not candidate version]

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

apt-get install php5-mysqlnd

Building dependency tree       
Reading state information... Done
Package php5-mysqlnd 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
However the following packages replace it:
  php5-mysql

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

我错过了什么？

    如果您使用的是Docker PHP5-apache 映像，那么所描述的行为很可能是由 APT 首选项文件 /etc/apt/preferences.d/no-debian-php 引起的。其中的内容似乎阻止了 APT 考虑任何与 PHP 相关的包。

    您正在使用的 docker 映像提供了一个源构建的 PHP，APT PHP 包在这里不会帮助您。如果您需要为 docker 镜像中安装的 PHP 添加扩展，您应该使用文档中描述的帮助脚本从源代码构建。
