Laravel new コマンド PHP Fatal error: Uncaught Error: Call to undefined method

Posted at

Laravelインストーラを使ってインストールした時にエラーが起きた場合の対処法です。

問題

$ laravel new project-name
Crafting application...
PHP Fatal error:  Uncaught Error: Call to undefined method Symfony\Component\Process\Process::fromShellCommandline() in /Users/ucan/.composer/vendor/laravel/installer/src/NewCommand.php:84

Laravelインストーラが古いので更新しましょう...😅

対策

$ composer global update

ディレクトリは作成されてるので削除してやり直しましょう。

$ rm -rf project-name
$ laravel new project-name
$ php artisan -V
Laravel Framework 7.10.3

バージョン表示できたらokです。
