Your Composer dependencies require the following PHP extensions to be installed: pcntl

Posted 2020-12-21 wayne2018

 

问题原因是 Windows不支持pcntl库 ，参考 https://stackoverflow.com/questions/30045085/how-to-install-pcntl-extension-in-windows 

 

解决方案：

      https://stackoverflow.com/questions/48577465/how-can-i-solve-laravel-horizon-v1-1-0-requires-ext-pcntl-the-requested-ph 

   由于pcntl模块涉及到swoole依赖，本地测试可以先不管

 

 

参考 https://github.com/composer/composer/issues/9340 

 

问题分析：这个问题是laravel框架的问题，但是由于项目是早期版本开发的，所以laravel框架不能升级！ 资料建议降低composer的版本

 

降低版本：composer self-update --1

 

忽略错误：composer install --ignore-platform-reqs

 

编译结果：

 

Discovered Package: nunomaduro/collision

 

Discovered Package: simplesoftwareio/simple-qrcode

 

Discovered Package: vinkla/hashids

 

Discovered Package: vladimir-yuldashev/laravel-queue-rabbitmq

 

Discovered Package: yansongda/laravel-pay

 

Discovered Package: zanysoft/laravel-zip

 

Package manifest generated successfully.

 

接下来再执行 php artisan make 的各种命令就正常了

 

   忽略错误：composer install --ignore-platform-reqs
