安装时出现ErrorException

Question

尝试使用时安装：

composer require "arcanedev/log-viewer:~3.0"

我得到了：

  

[ErrorException]         声明Arcanedev \ LogViewer \ LogViewerServiceProvider :: registerConfig（）应该   兼容   Arcanedev \ Support \ PackageServiceProvider :: registerConfig（$ separator =   ''）

有什么想法吗？

composer.json
