php - 供应商更新破坏了 FOS 用户包 "Call to a member function has() on a non-object"

Question

我为 Symfony 2.8 项目更新了我的供应商，突然登录页面没有加载——相反我得到了这个:

Error: Call to a member function has() on a non-object in vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Controller/Controller.php at line 184

Answer 1

我已经多次看到这种问题，但我找不到一个可以接受的答案和解释。就这样吧。

基本问题在于:

"friendsofsymfony/user-bundle": "~2.0@dev",

当 Symfony 2.8/3.0 首次发布时，稳定的 1.x 版本的 FOSUserBundle 不再有效。 2.x 版本已经开发多年，目前尚无实际路线图确定何时稳定。因此，开发分支被黑客入侵以使其正常工作。人们别无选择，只能使用它，这当然很危险，因为您永远不知道开发更改何时可能会破坏您的代码。

时间流逝，最终发布了 FOSUserBundle 的稳定 2.x 版本。然而，相当多的开发人员从未抽出时间更新他们的依赖项并继续使用 master 分支。

快进到现在。 Symfony 4 的发布现在已经在 master 分支中引发了大量的开发。对现有 2.8(可能还有 3.0)代码引入重大更改的开发。

底线是使用一个稳定的分支:

"friendsofsymfony/user-bundle": "~2.0",

随后是 Composer 更新。
