Answer 1

如果您安装了两个不同的插件来请求相机的权限，即 cordova-plugin-qrscanner 和 phonegap-plugin-barcodescanner 一起安装，就会导致这个问题。

删除任一插件

ionic cordova plugin remove phonegap-plugin-barcodescanner

或

ionic cordova plugin remove cordova-plugin-qrscanner

Answer 2

是的。@Jay 是对的。因为我的 ionic 项目安装了两个不同的插件，它们需要相机的许可。 cordova-plugin-qrscanner 和 cordova-plugin-cszbar，删除其中一个插件然后工作。
