问题1：

Drupal10下载模块时，官方更推荐使用composer下载安装。因为一些模块会有很多依赖，手动下载较为麻烦，而composer则会将依赖模块一并下载。

而在使用composer下载时会出现以下错误：

root@f6e5485502e2:/opt/drupal# composer require 'drupal/yunke_help:^2.4'
./composer.json has been updated
Running composer update drupal/yunke_help

解决：

参考：https://blog.csdn.net/HTML1033808020/article/details/124949278

根据报错信息，发现是因为该镜像源没有这个包或者composer版本过低而引起的报错，因此首先选择更换源：

composer config -g repo.packagist composer https://mirrors.cloud.tencent.com/composer/
## 通过该命令，镜像源修改成功
## 有些镜像源在composer.json中已经设定了，此时需要修改composer.json文件

问题2：

更换源之后，继续执行composer命令，又出现了下述错误：

root@f6e5485502e2:/opt/drupal# composer require 'drupal/yunke_help:^2.4'
./composer.json has been updated

分析上述报错，发现是连接超时（Connection timed out），猜测可能是docker hub不太稳定，多尝试几次之后就成功了。
