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 – 而是我得到了这个：

我已经多次看过这样的问题,但我找不到一个接受了答案和解释的问题.所以这里.
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,没有实际的路线图可以确定何时稳定.所以开发分支被破解以使其正常工作.人们别无选择,只能使用它当然是危险的,因为你永远不知道发展变化何时可能会破坏你的代码.
时间流逝,最终发布了稳定的2.x版本的FOSUserBundle.但是,相当多的开发人员从未到过更新其依赖关系并继续使用master分支.
快进到现在. Symfony 4的发布现在已经在主分支中引发了相当大的发展.开发正在对现有的2.8(可能是3.0)代码进行重大更改.
底线是使用稳定的分支：
"friendsofsymfony/user-bundle": "~2.0",
然后是作曲家更新.
