目标入口点“ @ angular / fire /数据库”缺少依赖项：-@ angular / core

问题描述

即使我的本地node_modules中安装了@ angular / core版本，在我的项目文件夹中运行ionic serve后，我仍然会遇到此错误。是什么导致此问题，如何解决？似乎没有任何错误，因为直到我开始使用mapbox时才抛出错误，如下所示。这是我的 package.json ：

当我运行ng version时，这是我的输出：

这是我到目前为止尝试过的：

• 卸载并重新安装@ angular / fire
• 删除node_modules并运行npm install
• 取消链接@ angular / fire （但是，当我尝试卸载/取消链接@ angular / fire时，在运行ionic serve时，仍然会收到关于@ angular / fire / database缺少依赖项的错误）
