【问题描述】：

我为 composer 设置了环境变量，但它仍然安装到默认目录 (~/.composer)。如果我做错了什么，谁能告诉我？

distPoint /var/www/html/laravel # COMPOSER_HOME="/opt/composer/"
distPoint /var/www/html/laravel # echo $COMPOSER_HOME
/opt/composer/
distPoint /var/www/html/laravel # composer global require "laravel/installer=~1.1"
Changed current directory to /root/.composer
./composer.json has been created

【问题讨论】：

您还需要export 环境变量。否则子进程将看不到它。（例如，XDG_CONFIG_HOME 默认导出，因为这是平台兼容工具如今使用的。）

标签： php linux bash ubuntu composer-php

【解决方案1】：

使用这个inseead：

export COMPOSER_HOME=/opt/composer

它使变量可用于子进程。
