باسلام و احترام

اگر مشکل نبودن دایرکتوری vendor بعد از نصب لاراول رو شما هم دارید
و دستور php artisan serve هم کار نمیکنه

اگر معمولا هرچی از دستور composer install استفاده میکنید ارور هایی مثل نبود فایل composer.lock و یا مشکلی در اکستنشن های php میده

من راه زیر رو از سایت stackoverflow.com پیدا کردم و درست شد

البته سیستم عامل من لینوکس/ابونتو هست شاید در ویندوز فرق کنه یا اصلا این مشکل رو نداشته باشید شما (اینو استاد توضیح بدن)

من فقط دستور زیر رو در ترمینال وارد کردم

sudo apt-get install php-mbstring php-dom

composer install

سلام استاد من 3 روزه خواب نداشتم هرکاری میکنم نمیشه لاراول رو نصب کنم ورژن php هم 8.2 هستش لاراول 6 رو میخوام نصب کنم این ارور هارو میده به پروکسی هم وصل شدم بازم همین ارور رو میده git رو هم نصب کردم نشد.

Package swiftmailer/swiftmailer is abandoned, you should avoid using it. Use symfony/mailer instead.

Package symfony/debug is abandoned, you should avoid using it. Use symfony/error-handler instead.
