Question

我正在关注本教程：Laravel 5.6 in Docker with PHP 7.2, NGINX 1.10 and MySQL 5.7

基本上是对此的更新：Laravel + Docker Part 1 — setup for Development

但是当我跑步时

docker-compose up

我收到了这个错误

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

完整输出

有没有人知道如何解决它？

Answer 1

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会安装推荐但不建议的软件包。使用--no-install-recommends，仅安装主要依赖项（Depends字段中的包）。

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

您应该能够构建图像，因此docker-compose up命令可以正常工作。

Docker：E：无法找到包mysql-client --no-install-recommended
