I have symfony installed and I am currently learning it. I should also note that I am using Ubuntu 15.04 on this system.
So I ran the following command to create a demo:
symfony demo
Then I run
php app/console server:run
Which lets me run the demo. So I go to the given URL for the server. I click "browse application". The app has errors all over the place. On this page it gives me the following errors:
An exception occured in driver: could not find driver
500 Internal Server Error - DriverException
2 linked Exceptions: PDOException » PDOException »
[3/3] DriverException: An exception occured in driver: could not find driver +

k. I try to fix the first error, PDOException. I find some links. They suggest installing:
sudo apt-get install php5-sqlite php5-mysql
mysql is installed. sqlite says that it has unmet dependencies and all this stuff:
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.
Not sure what to do from here.
答案 0 :(得分：0)
我这样做了：
sudo apt-get install php5-sqlite
它的工作正常，因为演示需要sqlite驱动程序。
