How can I solve "laravel/horizon v1.1.0 requires ext-pcntl * -> the requested PHP extension pcntl is missing from your system"?
提问by Success Man
When I run composer installon command promp, there exist error like this :
当我composer install在命令提示符上运行时，存在如下错误：
Problem 1
- Installation request for laravel/horizon v1.1.0 -> satisfiable by laravel/horizon[v1.1.0].
- laravel/horizon v1.1.0 requires ext-pcntl * -> the requested PHP extension pcntl is missing from your system.
To enable extensions, verify that they are enabled in your .ini files:
- C:\xampp-7.1\php\php.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
How can I solve this error?
我该如何解决这个错误？

Run composer with the --ignore-platform-reqsoption and specify pcntland posix
使用--ignore-platform-reqs选项运行 composer并指定pcntl和posix
composer install --ignore-platform-reqs

As per the accepted answer, but you can add this to your composer.json so that you don't have to run --ignore-platform-reqsall the time
按照接受的答案，但你可以添加到您的composer.json，这样你就不必运行--ignore-platform-reqs所有的时间
"config": {
"platform": {
"ext-pcntl": "7.3",
"ext-posix": "7.3"
}
}

Please see these github issues on laravel/horizonpage #131, #78.
请在laravel/horizon页面#131, #78上查看这些 github 问题。
I suggest you use Laravel Homesteadon your Windows system, It is easy to setup and will save you from many of the similar problems in future.
我建议你在你的 Windows 系统上使用Laravel Homestead，它很容易设置并且可以避免你将来遇到许多类似的问题。

If you are using docker based on a Unix image you can add it with the docker utility:
如果您使用基于 Unix 映像的docker，您可以使用docker 实用程序添加它：
docker-php-ext-install pcntl
You can then confirm that this extension is installed and enabled inside of your container:
然后，您可以确认在您的容器内安装并启用了此扩展：
?> php -i | grep pcntl
/usr/local/etc/php/conf.d/docker-php-ext-pcntl.ini,
pcntl
pcntl support => enabled

I have installed PHP 7.2 instead of 7.1 and everything works fine now. It appears that pcntl was not present in 7.1 but it's installed with php 7.2.
我已经安装了 PHP 7.2 而不是 7.1，现在一切正常。看来 pcntl 在 7.1 中不存在，但它与 php 7.2 一起安装。

If you're running on windows 10 without homestead you can enable the linux subsystem and run horizon through that.
如果您在没有 homestead 的情况下在 Windows 10 上运行，您可以启用 linux 子系统并通过它运行地平线。

Then install the requirements
然后安装需求
sudo apt install php7.2-fpm php7.2-mbstring php7.2-xmlrpc php7.2-soap php7.2-gd php7.2-xml php7.2-cli php7.2-zip php7.2-mysql
This also can run laravel envoy too which doesn't work on windows.
这也可以运行 laravel envoy，但在 Windows 上不起作用。
It's a nice lightweight solution
这是一个很好的轻量级解决方案
