我真的需要這個幫助。我創建了一個應用程式（帶有登錄和注冊），允許您監控正在進行的專案及其相關任務。每個專案都有一個用戶作為創建者。我將它部署在 Heroku 上，當我創建一個專案時，我應該被重定向到我的帳戶（/account）并列出所有專案，但它不起作用。我知道該專案已創建，因為我可以在另一個 URL（如 ）上查看其詳細資訊/project/[id]/details，但我無法再回傳/accountURL。我在我的網站上收到此錯誤：
Oops! An Error Occurred
The server returned a "500 Internal Server Error".
Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

uj5u.com熱心網友回復：
未捕獲的 PHP 例外 Twig\Error\RuntimeError：“在渲染模板期間引發了例外（”Symfony\Polyfill\Intl\Icu\IntlDateFormatter::__construct() 方法的引數 $locale value 'fr' 行為未實作. 僅支持區域設定“en”。請安裝“intl”擴展以獲得完整的本地化功能。
所以，安裝intl擴展。
在 Heroku上，您可以通過在以下內容中添加 ext-intl依賴項來做到這一點composer.json：
{
"require": {
"ext-intl": "*"
}
}
然后提交并重新部署。
您可能還必須啟用適當的 locale，但請先查看上述是否可以單獨使用。
