php composer.phar create-project -sdev zendframework/skeleton-application zf3-helloworld
cd zf3-helloworld/
cp composer.phar zf3-helloworld/
cd zf3-helloworld/
php composer.phar update
I'm use PHP7.2
I installed several packages without problems, however try to install the package zendframework / zend-cache, I get the error:

I'm using the tutorial as a base:
https://olegkrivtsov.github.io/using-zend-framework-3-book/html/en/Zend_Skeleton_Application/Getting_Zend_Skeleton_Application.html
Typically, this occurs because of conflicting versions of packages
I recommend restarting the installation process, because your project is new, I think it is faster than resolving all conflicts.
First, clear the cache and data already installed:
rm -rf composer.lock vendor
php composer.phar clear
Restart installing the package with conflict problem
php composer.phar require zendframework/zend-session
After install anothers packages. Eg:
php composer.phar require zendframework/zend-cache
php composer.phar require zendframework/zend-mvc
php composer.phar require zendframework/zend-db
php composer.phar require zendframework/zend-modulemanager
php composer.phar require zendframework/zend-mvc
php composer.phar require zendframework/zend-mvc-i18n
php composer.phar require zendframework/zend-crypt
php composer.phar require zendframework/zend-escaper
php composer.phar require zendframework/zend-mail
php composer.phar require zendframework/zend-paginator
In the following tutorial that is, I think that marked Y switch instead of N, in answer for minimal installation packages.
Do you want a minimal install (no optional packages)? Y/n
n
But, the clear all data that solution your problem.

You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-xml --ignore-platform-req=ext-dom` to temporarily ignore these required extensions.
you should just install ext-xml
sudo apt-get install php-xml
laravel/pint needs this package for running correctly
my answer isn't different from Farid Saravi answer , and it solved my problem too
just want to add the answer for the second problem that appeared to me
mentioning that i'm using linux ubuntu 22.04
Problem 1
Root composer.json requires laravel/pint ^1.0 -> satisfiable by laravel/pint[v1.0.0, ..., v1.2.0].
- laravel/pint[v1.0.0, ..., v1.2.0] require ext-xml * -> it is missing from your system. Install or enable PHP's xml extension.
and its answer
sudo apt-get install php-xml
Problem 2
spatie/laravel-ignition[1.0.0, ..., 1.6.1] require ext-curl * -> it is missing from your system. Install or enable PHP's curl extension.
- Root composer.json requires spatie/laravel-ignition ^1.0 -> satisfiable by spatie/laravel-ignition[1.0.0, ..., 1.6.1].
and its answer
sudo apt-get install php-curl
First, delete the project that gave error when creating. Then
Run sudo apt-get install php8.2-curl
you can change php.8.2-curl according to the PHP version you use.
After this, create a project again. It will be successfully created

Can't install phpDocumentor via Composer
From the correct answer in the link I provided above, I know that the source of my problem is that I'm missing the XSL for my PHP. However, I don't know how to proceed on installing XSL for PHP 7.2. I'm running on MacOs with Homebrew and I tried to do the following:
brew install php72-xsl
I've noticed there's a xsl inside my php.ini:
;extension=xsl
However, when I uncomment it, I get the following warning:
PHP Startup: Unable to load dynamic library 'xsl' (tried: /usr/local/Cellar/php72/7.2.2_13/lib/php/extensions/no-debug-non-zts-20170718/xsl (dlopen(/usr/local/Cellar/php72/7.2.2_13/lib/php/extensions/no-debug-non-zts-20170718/xsl, 9): image not found)
I've checked and the file does not exist. Actually the whole folder extensions does not exist.
Can someone let me know how I should proceed to install xsl?
Brew-installed package php72 includes the xsl extension. Please undo your manual change to the php.ini.
You seem to have an dependency issue with phpdocumentor/reflection-docblock.
You can try the following
remove phpdocumentor/reflection-docblock from your composer.json
run composer update to update the composer.lock
add your phpdocumentor dependency
composer require --dev phpdocumentor/phpdocumentor
re-add phpdocumentor/reflection-docblock
composer require --dev phpdocumentor/reflection-docblock
If you don't have the phpdocumentor/reflection-docblock dependency in your composer.json, try to delete the composer.lock and the vendor folder
rm -rf vendor composer.lock
Then run composer require --dev phpdocumentor/phpdocumentor
This should resolve implicit version constraints with reflection-docblock
I'm trying to update PHPUnit version on a project I'm going to create based on Cilex. It has PHPUnit version ~3.7. When I run composer require phpunit/phpunit:~6 --dev it prints out:
Problem 1
- Can only install one of: phpunit/php-code-coverage[5.2.2, 1.2.18].
- Can only install one of: phpunit/php-code-coverage[5.2.2, 1.2.18].
- Can only install one of: phpunit/php-code-coverage[5.2.2, 1.2.18].
- phpunit/phpunit 6.3.0 requires phpunit/php-code-coverage ^5.2.2 -> satisfiable by phpunit/php-code-coverage[5.2.2].
- Installation request for phpunit/phpunit ^6.3 -> satisfiable by phpunit/phpunit[6.3.0].
- Installation request for phpunit/php-code-coverage (locked at 1.2.18) -> satisfiable by phpunit/php-code-coverage[1.2.18].
However it won't say which package is the offending one. The composer file is this one.
PS:
Also, I ran composer require php:~7.1 just in case, and it worked, but updating PHPUnit after that still doesn't work.
Require package with --update-with-dependencies
Run
$ composer require phpunit/phpunit:^6.0.0 --update-with-dependencies
to update phpunit/phpunit while updating its dependencies at the same time.
See https://getcomposer.org/doc/03-cli.md#require:
--update-with-dependencies: Also update dependencies of the newly required packages.
List reasons
If this doesn't help, run
$ composer why-not phpunit/phpunit:^6.0.0
to list reasons why the package could not be installed.
I'm trying to install this https://github.com/antonioribeiro/tracker package on my Laravel 5.2 using command:
composer require pragmarx/tracker
But then I get this error:

I don't want to break my application. What should I do?
The new package depends on ramsey/uuid, that line also tells you which versions have been found to satisfy this requirement:
pragmarx/tracker v2.0.0 requires ramsey/uuid ~2.8 -> satisfiable by ramsey/uuid[2.8.0, 2.8.1, 2.8.2, 2.8.3, 2.8.4, 2.9.0].
It seems that this package is already installed in a newer version, because these lines appears as well:
- Conclusion: remove ramsey/uuid 3.4.1
- Conclusion: don't install ramsey/uuid 3.4.1
Composer sums this up as following:
- Can only install one of: ramsey/uuid[2.8.0, 3.4.1].
Composer cannot install your new package because you have installed ramsey/uuid in a newer version that is incompatible to the required version.
You can try and send a pull request to the maintainer of pragmarx/tracker with the update of ramsey/uuid. Or you can search for a different package that is compatible with your installed packages.
