[英]How to troubleshoot PDOException?
I am developing a Laravel application that is talking to a Microsoft SQL server. 我正在开发与Microsoft SQL Server通讯的Laravel应用程序。 Everything works, but when I run
composer update
to update packages I receive the following error: 一切正常,但是当我运行
composer update
来更新软件包时,出现以下错误:
[PDOException]
could not find driver
Script php artisan clear-compiled handling the pre-update-cmd event returned with an error
[RuntimeException]
Error Output:
update [--prefer-source] [--prefer-dist] [--dry-run] [--dev] [--no-dev] [--lock] [--no-plugins] [--no-custom-installers] [--no-autoloader] [--no-scripts] [--no-progress] [--with-dependencies] [-v|vv|vvv|--verbose] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--ignore-platform-reqs] [--prefer-stable] [--prefer-lowest] [-i|--interactive] [--] [<packages>]...
The strange thing is that the sqlserv
driver set up in my database.php file works fine; 奇怪的是,在我的database.php文件中设置的
sqlserv
驱动程序运行良好; my vagrant box has the correct driver installed and configured and, as far as I can tell, everything regarding the database connection is working as expected. 我的游民箱已安装并配置了正确的驱动程序,据我所知,有关数据库连接的所有操作均按预期工作。
What steps can I take to try to narrow down the source of this error? 我可以采取哪些步骤来缩小此错误的根源?
Update : 更新 :
I did mention that my SQL connection is, as far as I know, configured correctly on the server: it works for querying, updating, etc. But just in case I missed something here are the full steps I took to install the SQL driver: 我确实提到,据我所知,我的SQL连接已在服务器上正确配置:它可用于查询,更新等。但是以防万一我错过了某些东西,以下是我安装SQL驱动程序的全部步骤:
sudo apt-get install php5-mssql php5-sybase
sudo php5enmod mssql
sudo nano /etc/freetds/freetds.conf
: sudo nano /etc/freetds/freetds.conf
:
[global] tds version = 8.0 client charset = UTF-8
sudo service apache2 restart
I was finally able to solve this by doing the following: 我终于可以通过执行以下操作解决此问题:
composer update
on the actual vagrant vm via ssh
ssh
在实际的虚拟机vm上运行composer update
