我正在升级我的angular 10项目，它运行在node 14.x和npm 6.14.x上，
npm ls在NPM中显示以下问题，

当将项目升级到Angular的新版本时，最好遵循the angular update guide并使用
ng upgrade进行更新。许多第一方Angular软件包相互依赖，只有在使用Angular团队定义的版本时才能一起工作。任何第三方Angular库（在正确构建时）都会在其package.json中定义
peerDependencies，以告诉您他们的包已经过测试并且可能会工作的版本。任何较新的主要版本都不能保证工作。当看到
npm ls的输出时，我认为你可以：所以我建议你首先尝试更新你的第三方软件包（最好使用
ng update），如果警告仍然存在，就给予你的应用一个尝试。如果它不起作用，那么你必须等待支持...
