PHP Laravel 错误 - 您的要求无法解析为一组可安装的软件包

Question

我正在尝试在 WSL2 ubuntu 中创建 laravel 项目。我在 WSL 根目录中有项目文件夹 (www)，在该文件夹中我有 laravel_test 子文件夹。当我运行时

composer create-project laravel/laravel example-app

但是我遇到了一个错误无法将您的要求解析为一组可安装的软件包。我该如何解决这个问题？

root@LAPTOP-R27NIA9B:~/www/laravel_test# composer create-project laravel/laravel example-app
Do not run Composer as root/super user! See https://getcomposer.org/root for details

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires laravel/pint ^1.0 -> satisfiable by laravel/pint[v1.0.0, v1.1.0, v1.1.1].
    - laravel/pint[v1.0.0, ..., v1.1.1] require ext-xml * -> it is missing from your system. Install or enable PHP's xml extension.
  Problem 2
    - phpunit/phpunit[9.5.10, ..., 9.5.x-dev] require ext-dom * -> it is missing from your system. Install or enable PHP's dom extension.
    - Root composer.json requires phpunit/phpunit ^9.5.10 -> satisfiable by phpunit/phpunit[9.5.10, ..., 9.5.x-dev].

To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/8.1/cli/php.ini
    - /etc/php/8.1/cli/conf.d/10-opcache.ini
    - /etc/php/8.1/cli/conf.d/10-pdo.ini
    - /etc/php/8.1/cli/conf.d/20-calendar.ini
    - /etc/php/8.1/cli/conf.d/20-ctype.ini
    - /etc/php/8.1/cli/conf.d/20-exif.ini
    - /etc/php/8.1/cli/conf.d/20-ffi.ini
    - /etc/php/8.1/cli/conf.d/20-fileinfo.ini
    - /etc/php/8.1/cli/conf.d/20-ftp.ini
    - /etc/php/8.1/cli/conf.d/20-gettext.ini
    - /etc/php/8.1/cli/conf.d/20-iconv.ini
    - /etc/php/8.1/cli/conf.d/20-phar.ini
    - /etc/php/8.1/cli/conf.d/20-posix.ini
    - /etc/php/8.1/cli/conf.d/20-readline.ini
    - /etc/php/8.1/cli/conf.d/20-shmop.ini
    - /etc/php/8.1/cli/conf.d/20-sockets.ini
    - /etc/php/8.1/cli/conf.d/20-sysvmsg.ini
    - /etc/php/8.1/cli/conf.d/20-sysvsem.ini
    - /etc/php/8.1/cli/conf.d/20-sysvshm.ini
    - /etc/php/8.1/cli/conf.d/20-tokenizer.ini
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.

Answer 1

你应该只安装 ext-xml

sudo apt-get install php-xml

laravel/pint 需要这个包才能正常运行
