如何解決這些錯誤的symfony框架演示？

Question

我已經symfony的安裝，我目前正在學習它。我也應該注意到，我在這個系統上使用Ubuntu 15.04。

於是我就下面的命令來創建一個演示：

symfony demo 

然後我跑

php app/console server:run 

，它可以讓我運行演示。所以我去了服務器的給定URL。我點擊「瀏覽應用程序」。該應用程序在各地都有錯誤。在這頁上，它給我以下錯誤：

k。我嘗試修復第一個錯誤，PDOException。我找到一些鏈接。他們建議安裝：

sudo apt-get install php5-sqlite php5-mysql 

mysql已安裝。 sqlite說，它有未滿足的依賴和所有這些東西：

Some packages could not be installed. This may mean that you have 
requested an impossible situation or if you are using the unstable 
distribution that some required packages have not yet been created 
or been moved out of Incoming. 
The following information may help to resolve the situation: 

The following packages have unmet dependencies: 
php5-sqlite : Depends: php5-common (= 5.6.4+dfsg-4ubuntu6) but 5.6.4+dfsg-4ubuntu6.4 is to be installed 
E: Unable to correct problems, you have held broken packages. 

不知道該從這裏做什麼。

Answer 1

我這樣做：

sudo apt-get install php5-sqlite 

而作爲演示需要的sqlite的驅動程序它工作得很好。
