问题描述

我正在关注本教程:这基本上是对此的更新: Laravel + Docker第1部分—开发设置

Which is basically an update of this: Laravel + Docker Part 1 — setup for Development

但是当我跑步

docker-compose up

我收到此错误

E: Unable to locate package mysql-client —-no-install-recommends
ERROR: Service 'app' failed to build: The command '/bin/sh -c apt-get update && apt-get install -y mysql-client —-no-install-recommends  && docker-php-ext-install pdo_mysql' returned a non-zero code: 100

有人知道如何解决吗?

推荐答案

图像缺少能够安装mysql-client的依赖项，这是由--no-install-recommends标志引起的.默认情况下，Ubuntu安装推荐但不推荐的软件包.使用--no-install-recommends，仅安装主要依赖项(依赖"字段中的软件包).

The image is missing dependencies to be able to install mysql-client, this is caused by the --no-install-recommends flag. By default, Ubuntu installs recommended but not suggested packages. With --no-install-recommends, only the main dependencies (packages in the Depends field) are installed.

将Dockerfile或根据文章app.dockerfile更改为:

FROM php:7.2.2-fpm RUN apt-get update && apt-get install -y mysql-client \ && docker-php-ext-install pdo_mysql

FROM php:7.2.2-fpm RUN apt-get update && apt-get install -y mysql-client \ && docker-php-ext-install pdo_mysql

您应该能够构建映像，因此docker-compose up命令将起作用.

And you should be able to build the image, therefore the docker-compose up command would work.
