Having trouble installing AdminBundle - php

Question

I'm trying to install Admin Bundle but it doesn't work and I don't know why,
Help me please!
$ composer require sonata-project/admin-bundle
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20131226/php_intl.dll' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20131226/php_intl.dll, 9): image not found in Unknown on line 0
 Using version ^3.20 for sonata-project/admin-bundle
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- The requested package sonata-bundle/admin-bundle could not be found in any version, there may be a typo in the package name.
Problem 2
- Conclusion: remove jms/di-extra-bundle 1.5.x-dev
- sonata-project/admin-bundle 3.20.0 conflicts with jms/di-extra-bundle[1.5.x-dev].
- sonata-project/admin-bundle 3.20.1 conflicts with jms/di-extra-bundle[1.5.x-dev].
- Installation request for jms/di-extra-bundle (locked at 1.5.x-dev, required as dev-master) -> satisfiable by jms/di-extra-bundle[1.5.x-dev].
- Installation request for sonata-project/admin-bundle ^3.20 -> satisfiable by sonata-project/admin-bundle[3.20.0, 3.20.1].
Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.
Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.
Installation failed, reverting ./composer.json to its original content.
There is my composer.json

Answer 1

The "sonata-bundle/admin-bundle": "*", line is present in your composer.json file, but that package does not exist (causing Problem 1). Remove it
jms/di-extra-bundle is required to be installed according to your composer.json file, but sonata-project/admin-bundle specifically disallows that package to be installed (see: GH-4292). It looks like, at this time, you'll need to choose either AdminBundle or JMSDiExtraBundle to use.
