php - 无法在Laradock中安装php7.2-ldap扩展

Question

我正在尝试在Laradock中安装php7.2-ldap并且已经设置

WORKSPACE_INSTALL_LDAP=true

和

PHP_FPM_INSTALL_LDAP=true

然后尝试建立像

docker-compose build workspace

我收到此错误消息。日志的一部分

这是怎么回事，为什么我不能安装它？

Answer 1

我在回答我自己的问题。

这是通过添加来解决的

apt-get update -yqq && \

之前

apt-get install -y libldap2-dev && \

在 workspace/Dockerfile和 php-fpm\Dockerfile中。

一个完整的块如下所示:

文件: workspace\Dockerfile

###########################################################################
# LDAP:
###########################################################################

ARG INSTALL_LDAP=false
ARG PHP_VERSION=${PHP_VERSION}

RUN if [ ${INSTALL_LDAP} = true ]; then \
    apt-get update -yqq && \
    apt-get install -y libldap2-dev && \
    apt-get install -y php${PHP_VERSION}-ldap \
;fi

为什么会发生这种情况？
来自Github的报价 issue:

What appears to be happening here is that there are a few apt-get install commands for several packages are called while the local package repo is out of sync with the remote. In an interactive environment, this would be seen by the user and an appropriate apt-get update would be run. However, the Dockerfile does not contain any package repo update commands, as such the current layer has a different package repo list than the remote. This is in general the "problem" with dockers layers as they will be re-used if their command didn't change (something I, too, had to learn the hard way).
