php - Symfony2 项目在本地主机上运行，​​在 EC2 上存在文件查找问题

Question

我有一个 Symfony2 项目，它使用了很多 3rd Party 包。我将 Sonata Admin Bundle 用于应用程序管理员。我几乎完成了我的项目开发，我正试图让它在 Amazon EC2 上运行。我正在使用 GIT 来部署我的应用程序，我已经成功地完成了所有设置，但我遇到了一个非常奇怪的问题。该项目在本地服务器上运行良好，但是当我上线时出现错误：

InvalidArgumentException: Unable to load class "Sonata\AdminBundle\Admin\Admin"

尝试运行应用程序/控制台命令时出现错误：

PHP Fatal error:  Class 'Sonata\BlockBundle\SonataBlockBundle' not found in /var/www/html/candulifestyle.com/app/AppKernel.php on line 25

Fatal error: Class 'Sonata\BlockBundle\SonataBlockBundle' not found in /var/www/html/candulifestyle.com/app/AppKernel.php on line 25

我很难在这里追踪问题。该项目在我的本地系统上运行良好。有没有人遇到过这样的问题。如果有人对此类问题有任何见解，请告诉我。

Answer 1

I had the same very strange problem (PHP Fatal error: Class 'Sonata\BlockBundle\SonataBlockBundle' not found although it was present in the right folder) on a DigitalOcean server (running Ubuntu 12.04), whereas I didn't have the problem on my Ubuntu 12.04 VM instance.

I finally found the solution to the problem.

I just had to update Composer as I should have already done before:

composer self-update

And then run again this:

composer install

And everything was fine again.
