Answer 1

正如您從消息中看到的那樣：您需要為PHP安裝ext-curl擴展。

要在Ubuntu中安裝它，您需要運行下一個命令：

sudo apt-get install php5-curl

不要忘記在它之后重啟apache（或fpm）：

sudo service apache2 restart

或者fpm：

sudo service php5-fpm restart

Answer 2

錯誤消息告訴您sensio / distribution-bundle v4需要sensiolabs / security-checker v2.0.x，而后者又需要PHP curl擴展，但未安裝。 因此，作曲家不能（目前）滿足你的composer.json中指定的要求。 在基本級別，您需要安裝curl擴展。

為什么在您的情況下發生這種情況很難確定，沒有更多細節：

• 您最近是否已從分發包v3升級到v4？ 看起來在這些之間引入了對安全檢查程序的依賴性。 您可以恢復到v3以避免此問題。
• PHP環境是否已更改，以刪除curl擴展名？
