EasyAdmin 2.0.*和Symfony 3.4 composer错误

Question

我正在尝试在symfony3.4上安装EasyAdminBundle 2.0.*版本，但composer显示冲突。我试着与包装师确认哪里会有问题，但我没有找到任何提示。有人能帮我读一下composer error吗？是否可以在Symfony 3.4上安装EasyAdmin 2.*？我的php版本是7.1.14。

提前谢谢你。托马斯

Answer 1

EasyAdminBundle 2.0需要symfony 4.1，因此请升级symfony，或使用EasyAdminBundle 1.17.19 ( 1.x分支的最新版本)
