我照這個裝 https://pandalab.org/articles/90
這裡就出現問題
composer global require laravel/installer

C:\xampp\htdocs>composer self-update
You are already using the latest available Composer version 2.1.12 (stable channel).

C:\xampp\htdocs>composer global require laravel/installer

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

  Problem 1
    - laravel/installer[v4.2.0, ..., v4.2.9] require symfony/console ^4.0|^5.0 -> satisfiable by symfony/console[v4.3.5].
    - symfony/console v4.3.5 requires php ^7.1.3 -> your php version (8.0.12) does not satisfy that requirement.
    - Root composer.json requires laravel/installer ^4.2 -> satisfiable by laravel/installer[v4.2.0, ..., v4.2.9].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require laravel/installer:*" to figure out if any version is installable, or "composer require laravel/installer:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

--ignore-platform-reqs參數可以加在composer global require命令中嗎？

我才疏學淺只看得懂你的php版本太高
- symfony/console v4.3.5 requires php ^7.1.3 -> your php version (8.0.12) does not satisfy that requirement.

他看起來要php7.1.3以上沒有要php8

他有建議composer require laravel/installer:^2.1 你可以試試看

移除然後加上--with-all-dependencies參數來裝裝看（一開始的錯誤提示就有寫）。我把php換成8來試裝並沒問題，裝上的laravel/installer是4.2.9，搭配的symfony/console是5.3.11，看起來問題出在symfony/console的版本無法跟你的php版本搭配的樣子。也許讓composer根據需要去昇/降級版本就可以成功（錯誤提示也是這樣說）。

請問用 composer fund 打什麼指令可以昇或降級

建議用linux 環境安裝k8s，然後容器化開一個laravel環境出來
這樣會比較快，而且容器化是未來的趨勢，早接觸晚接觸都要接觸
趁早打底會比較好

composer fund 是用來看哪個package現在再找贊助

請嘗試composer require laravel/installer:^4.2

我是 win 10 , 要先裝 virtuxbox + centos + k8s + php + mysql + + composer + laravel , 順序是這樣嗎

只需要裝 virtuxbox + centos + php + composer + laravel
windows也可以用wsl去跑ubuntu，但裡面還是有不少坑拉
等你laravel能用再來安裝剩餘的部分
要怎麼裝請自己谷哥喔

我是用virtualbox裝linux，在上面使用laradock，自己開發使用上很夠用

我現在 win 10 + vmware + ubuntu , 但執行起來會遲鈍 , 我的 ram 只有 4 G , 是不是該加 ram

應該是PHP 版本問題

     -laravel/installer[v4.2.0, ..., v4.2.9] require symfony/console ^4.0|^5.0 -> satisfiable by symfony/console[v4.3.5].
     -symfony/console v4.3.5 requires php ^7.1.3 -> your php version (8.0.12) does not satisfy that requirement.
     -Root composer.json requires laravel/installer ^4.2 -> satisfiable by laravel/installer[v4.2.0, ..., v4.2.9].

安裝Laravel 4.2 要PHP 5.4 以上版本。

PHP >= 5.4

PHP 版本不能太新不能太舊，個人建議用5.4就好!

謝謝答覆 , 原來太新還不行 , 我去下載 5.4 卻無法下載 , 是這個網頁嗎 ?
