php - E : Package 'php-xmlrpc' has no installation candidate

Question

尝试在已安装 php7.3 的镜像上安装 php-xmlrpc。

如您所见，我尝试了 apt-get update 但没有帮助。我也尝试过使用php7.3-xmlrpc。

Dockerfile 行: 运行 apt-get update && apt-get install php-xmlrpc -y

Docker 构建输出:

E: Package 'php-xmlrpc' has no installation candidate

Answer 1

Docker 文件:

FROM php:7.3-apache

RUN apt-get update -y && apt-get upgrade -y;
RUN apt-get install -y libxml2-dev
RUN docker-php-ext-install -j$(nproc) xmlrpc

这有效。

如果你这样构建:

docker build --tag stackoverflow .

然后您可以通过运行命令检查已安装的扩展:

docker run -it --entrypoint="" --rm stackoverflow /bin/bash

然后在控制台中输入

php -m

给出输出:
