As the error message said Root composer.json requires PHP extension ext-intl * but it is missing from your system. Install or enable PHP's intl extension.

Make sure you have already installed/enabled PHP Intl extension in your web server, then restart your web server. (See Composer.)

If u use window os and php 7.xx above after enable ext intl but problem still occur, make sure to install microsoft c++ 2017 redistributable also, set system variable path in windows to your php instalation directory. That fixed for me.

Your requirements could not be resolved to an installable set of packages. Problem 1 - codeigniter4/framework[4.0.0, ..., v4.1.1] require ext-intl * -> it is missing from your system.

Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.

Solution 1

Run composer with the --ignore-platform-reqs option and specify pcntl and posix

composer install --ignore-platform-reqs

Solution 4

pcntl extension is not supported on Windows. (based on your XAMPP information)

Please see these github issues on laravel/horizon page #131, #78.

I suggest you use Laravel Homestead on your Windows system, It is easy to setup and will save you from many of the similar problems in future.

Example #1 (LAMP). actual item described was needed

composer require phpoffice/phpspreadsheet

Error produced: missing php-mstring
yum install php-mbstring

Example #2 (LAMP). something slightly different than the item described was needed

composer require phpoffice/phpspreadsheet

Error produced: missing ext-zip
yum install php-pecl-zip

Also, perhaps running composer in verbose mode?

But, I think your best bet to start is the first link provided in this answer (and then looking through similar WAMP Composer missing item issues).

According to PHP Official Documentation, You’ll have to find your extension in php.ini and uncomment it OR add it in general. It’s probably something like extension=php_http.dll.

Had the same problem in composer.json file. Also discovered, that I have an "ext-http": "*". To solve this problem just delete the "ext-http": "*" and try to install package again. Worked for me, hope for you too 🙂

In my case, the combination worked (Ubuntu php7.4)

sudo apt install php-pear
pecl install pecl_http

I had the same problem too.
My problem was that when I use RuntimeException class, I made a mistake by import use http\Exception\RuntimeException; instead of the standard one use RuntimeException. And the class http\Exception\RuntimeException; required ext-http extension.
So my suggestion is that, you should search your all project and check whether you made the same mistake as mine or not. You can search all by keyword use http\.
Btw I don’t think install or unstall ext-http plugin will solve the problem.

In case someone needs it, one can also install it with pecl
(it needs extensions raphf and propro loaded to build):

yum install libcurl-devel brotli-devel
pecl install pecl_http

You should add "extension=http.so" to php.ini

For those who encountered with this problem:

- The requested PHP extension ext-http * is missing from your system.

The solution is just to install PHP extension:

sudo apt install php-pecl-http

php-http is a standard which is implemented by different packages. ext-http is the Composer way to tell that your application requires at least one of those packages. See the section called «Composer virtual packages» at http://docs.php-http.org/en/latest/clients.html for additional details.

You should be able to fix your issue by installing one of the provided packages, e.g.

composer require php-http/curl-client

Update:
It might be worth looking at the other answers too. Since I’m no longer working with PHP, I’m not going to set up a project and try to recreate the problem I had just to test the new suggested solutions. If another answer did help you, give it a vote ‘^’ this way I know which answers are helpful.

The solution is found. For some reason my composer.json contained "ext-http": "*".

"require": { "ext-http": "*"
}

Removing this line fixed the problem. I don’t know why it contained "ext-http": "*" and I don’t fully understand why removing it would fix the problem. (Is it because it is looking for the extension, but can not find it?)

(Thank you to everyone trying to help me fix the problem!)

Solution 5

If you are using docker based on a Unix image you can add it with the docker utility:

docker-php-ext-install pcntl

You can then confirm that this extension is installed and enabled inside of your container:

?> php -i | grep pcntl
/usr/local/etc/php/conf.d/docker-php-ext-pcntl.ini,
pcntl
pcntl support => enabled

How can I solve «laravel/horizon v1. 0 requires ext-pcntl * -> the requested PHP extension pcntl is missing from your system»?

When I run composer install on command promp, there exist error like this :

 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?

Solution 2

As per the accepted answer, but you can add this to your composer.json so that you don’t have to run --ignore-platform-reqs all the time

"config": { "platform": { "ext-pcntl": "8.0", "ext-posix": "8.0" }
}

Example #1 (LAMP). actual item described was needed

composer require phpoffice/phpspreadsheet

Error produced: missing php-mstring
yum install php-mbstring

Solution 3

install horizon this way :

composer require laravel/horizon --ignore-platform-reqs

php artisan horizon:install

Example #2 (LAMP). something slightly different than the item described was needed

composer require phpoffice/phpspreadsheet

Error produced: missing ext-zip
yum install php-pecl-zip

Also, perhaps running composer in verbose mode?

But, I think your best bet to start is the first link provided in this answer (and then looking through similar WAMP Composer missing item issues).
