在 Docker 中安装 pecl 时出现"No releases available"错误

Question

我试图安装Xdebug或Redis包在Docker容器从pecl。安装失败并返回错误:

软件包"pecl.php.net/xdebug"没有可用的发行版。

Xdebug示例:https://pecl.php.net/package/xdebug/3.1.0

我php.dockerfile

FROM php:7.4-fpm
WORKDIR /var/www/html
RUN apt-get update && 
apt-get install ca-certificates && 
apt-get clean
RUN docker-php-ext-install pdo pdo_mysql
RUN pecl install xdebug 
&& docker-php-ext-enable xdebug 
&& echo "xdebug.remote_enable=on" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini 
&& echo "xdebug.remote_host = host.docker.internal" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

错误的原因是什么，我如何修复它?

Answer 1

您可能在代理服务器后面…我通过专门为PECL设置代理解决了同样的问题(单独的环境变量$HTTP_PROXY不起作用)。

RUN pear config-set http_proxy ${http_proxy} &&
pear config-set php_ini $PHP_INI_DIR/php.ini
RUN pecl install xdebug-3.1.1 && docker-php-ext-enable xdebug

我遇到了类似的问题，不得不更换我安装xdebug的方式

:

RUN pecl install xdebug-2.9.2 && docker-php-ext-enable xdebug

:后

RUN cd /tmp && 
git clone https://github.com/xdebug/xdebug.git && 
cd xdebug && 
git checkout xdebug_2_9 && 
phpize && 
./configure --enable-xdebug && 
make && 
make install && 
rm -rf /tmp/xdebug
RUN docker-php-ext-enable xdebug
