如何解决失败[INSTALL_FAILED_USER_RESTRICTED：用户取消安装]
我正在尝试通过Ionic 5运行一个android应用程序，但所有时间都在崩溃并出现此错误，并且不知道该怎么办，我试图删除node_modules，package-lock.json...。但没有任何办法可以解决

我没有得到它的详细信息，我现在更新了一些内容，但尝试了太多事情，却失去了踪迹。
已更新：
当我更新npm或cordova时发生了某些事情，它甚至崩溃了，甚至删除了所有内容并进行了git clone崩溃……请我需要帮助，第一次提交都不起作用（应该可以）
已更新：
如果我将APK手动传递到手机上，它会起作用，哪里出问题了？
