I'm trying to do a composer install in a Laravel project cloned from git.

But im getting some errors.

The first one that I solved was:

- phpunit/phpunit[8.5.0, ..., 8.5.x-dev] require ext-dom * -> it is missing from your system. Install or enable PHP's dom extension.

By doing:

sudo apt install php7-4-xml php7.4-mbstring

But now when I do a composer update or composer install I’m getting this answer:

PHP Fatal error: Uncaught Error: Class 'Normalizer' not found in /usr/share/php/Symfony/Component/Console/Helper/Helper.php:129.

Stack trace:

  • Does this answer your question? [Class Normalizer not found (in PHP 5.3.8)](https://stackoverflow.com/questions/8597146/class-normalizer-not-found-in-php-5-3-8) – Deepak Feb 21 '22 at 18:00
  • Please share more details. Which version of Symfony do you use? Searching through some versions, I could not find the code that triggers this problem. – Nico Haase Feb 22 '22 at 07:58
  • When I run the "Composer" command, I get the same error. I can tell you the version of Composer, which is installed. But symfony I have been unable to find the version. The version of Composer is 2.0.9. – Paco Cayuela Sanchez Feb 23 '22 at 15:15

    Why not update that version? It's more than a year old, and maybe that's a bug that has been fixed? – Nico Haase Feb 23 '22 at 15:23
  • Also, as your code seems to run in `/usr/share/php`: how did it get there? Did you install Symfony over your system's package manager? – Nico Haase Feb 23 '22 at 15:26
  • Sorry for the absence and the delay. Finally, due to others problems with the OS I've decided to reinstall the OS. I was able to install the project without any problem after that. – Paco Cayuela Sanchez Mar 01 '22 at 15:14

It requires php-intl to be installed

Normalizer class comes with the php internationalization extension (php-intl). It must be installed for using the Normalizer class

on debian i did

sudo apt install php-intl

It should fix the problem

Firstly you can try to install php-intl package

sudo apt install php-intl

If it doesn't help, you can run following commands one by one to upgrade php version to 8.1. (for Debian based OS):

sudo apt update
sudo apt upgrade
sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt install php8.1 php8.1-cli php8.1-fpm php8.1-apcu php8.1-opcache php8.1-common php8.1-curl php8.1-zip php8.1-mcrypt php8.1-mysql php8.1-mbstring php8.1-xml php8.1-gd php8.1-imagick php8.1-xmlrpc php8.1-maxminddb
sudo update-alternatives --set php /usr/bin/php8.1

Then check php version:

php --version

This helped me to fix error.

To solve it you need to install newer version of php 8.1

    Please add some explanation to your answer such that others can learn from it. From my POV, nothing in the question indicates that PHP 8.1 would magically solve the problem – Nico Haase Jul 12 '22 at 12:28

I had this issue and managed to fix it by uninstalling composer, then reinstalling composer correctly from the right repositories. I was using sudo-apt get composer, which was the issue.

This could be fixed by installing Composer directly from their website.

Remove the one installed with the package manager of your OS, then run:

curl -sS https://getcomposer.org/installer | php && sudo mv composer.phar /usr/local/bin/composer
