PHP Laravel 錯誤 - 您的要求無法解析為一組可安裝的軟件包

Question

我正在嘗試在 WSL2 ubuntu 中創建 laravel 項目。我在 WSL 根目錄中有項目文件夾 (www)，在該文件夾中我有 laravel_test 子文件夾。 當我跑

composer create-project laravel/laravel example-app

但我收到一個錯誤，您的要求無法解析為一組可安裝的軟件包。 我該如何解決這個問題？

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
Continue as root/super user [yes]? Y

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

我的答案與 Farid Saravi 的答案沒有什么不同，它也解決了我的問題只是想為我出現的第二個問題添加答案

提到我正在使用 linux ubuntu 22.04

問題1

• Root composer.json 需要 laravel/pint ^1.0 -> 可由 laravel/pint [v1.0.0, ..., v1.2.0] 滿足。 - laravel/pint[v1.0.0, ..., v1.2.0] 需要 ext-xml * -> 你的系統中缺少它。 安裝或啟用 PHP 的 xml 擴展。

及其答案

sudo apt-get install php-xml

問題2

spatie/laravel-ignition[1.0.0, ..., 1.6.1] 需要 ext-curl * -> 您的系統中缺少它。 安裝或啟用 PHP 的 curl 擴展。 - Root composer.json 需要 spatie/laravel-ignition ^1.0 -> 可由 spatie/laravel-ignition[1.0.0, ..., 1.6.1] 滿足。

及其答案

sudo apt-get install php-curl

Answer 2

你應該只安裝 ext-xml

sudo apt-get install php-xml

laravel/pint 需要這個 package 才能正常運行

Answer 3

首先，刪除創建時出錯的項目。 然后

運行sudo apt-get install php8.2-curl

您可以根據您使用的PHP版本更改php.8.2-curl。

在此之后，再次創建一個項目。 就會創建成功
