php 消息队列之安装think-queue： composer require topthink/think-queue遇到的错误

准备下载

最开始使用composer官网作为packagist，下载超时，科学上网也安装不了

[Composer\Downloader\TransportException]
  curl error 28 while downloading https://repo.packagist.org/p2/symfony/process.json: Timeout was reached

将地址换为国内镜像（全局 去点 -g 就是只当前项目）

composer config -g repo.packagist composer https://packagist.phpcomposer.com

然后执行

composer require topthink/think-queue

发现没有think-queue,这个包。

再切换成最后将packagit换成阿里云的地址：

 全局配置阿里云镜像：

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

仅当前工程：

composer config repo.packagist composer https://mirrors.aliyun.com/composer/

并再次执行

composer require topthink/think-queue

报错 Could not find a version of package encore/laravel-admin matching your minimum-stability (dev). Require it with an explicit version constraint allowing its desired stability.

1. 建议先将Composer版本升级到最新：

composer self-update

2. 执行诊断命令：

composer diagnose

3. 清除缓存：

composer clear

4. 若项目之前已通过其他源（比如composer官网）安装，则需要更新 composer.lock 文件，执行命令：

composer update --lock

再此尝试安装消息队列

composer require topthink/think-queue
