好的，我已经在这里待了两个小时了，我看到其他人有这个错误，但我似乎无法与他的原因/决议相符。
致命错误：require（）[function.require]：无法在第55行的/var/www/biztv_symfony/vendor/symfony/src/Symfony/Component/ClassLoader/DebugUniversalClassLoader.php中重新声明类companycontroller
终端提供了一个更好的错误消息，指出我报告遇到问题的实际类的结束子句（尝试重新声明）。
如果我删除或重命名文件companyController.php，它会抛出一个Symfony2错误，说它正在查找该类，但没有找到它在预期的位置。
如果我把文件放回原位，apache会抛出一个php错误，说不能重新声明类companyController。
我只有一次？！
以下是整个课程......如果有人有耐心尝试帮助我......

所以，事实证明这是一个由moi在那里发生的一堆错字。
但是对于在Symfony2中遇到此错误消息的任何人：
致命错误：require（）[function.require]：无法重新声明类...
这是一个提示：检查你是否有意外删除或拼写错误：在包含php声称它试图重新定义的类的定义的文件中的命名空间。
php错误消息并没有真正为您提供寻找的信息... =）
答案 1 :(得分：0)
redeclare class - 可能有两个同名的课程
答案 2 :(得分：0)
有时，如果您被复制/粘贴诱惑，请检查您的类名，命名空间以及可能发生的其他“拼写错误”。 （复制/粘贴是编程的魔鬼：/）
答案 3 :(得分：0)
与其他答案类似，在我的情况下，我已经重命名了类，但没有重命名包含文件。应该在具有相同名称的文件中声明每个类。所以也要检查一下。
答案 4 :(得分：0)
就我而言，它是命名空间下的use语句，它使用相同的类名（但是另一个路径）。
namespace Bsz\RecordTab;
use \Bsz\Config\Libraries; // I used this in constructor
class Libraries
{
...
}
没有use指令，它工作
答案 5 :(得分：0)
就我个人而言，我手动删除了缓存并且工作正常
rm -rf app/cache/*
清除缓存并没有解决我的问题。
