Answer 1

With peerDependencies you are required to download those packages yourself (the user consuming your library needs to download those packages, it doesn't come bundled with your library).(使用peerDependencies您需要自己下载那些软件包（使用您库的用户需要下载那些软件包，但它并不与您的库捆绑在一起）。)

So you will need to install those libraries manually in-order for you to use them.(因此，您将需要按顺序手动安装这些库才能使用它们。) If a user installs your library without those dependencies already installed, they will get a warning in their console.(如果用户在未安装这些依赖项的情况下安装您的库，则他们将在控制台中收到警告。) By adding a package in peerDependencies you are saying: My code is compatible with this version of the package.(通过在peerDependencies中添加一个软件包，您的意思是：我的代码与此版本的软件包兼容。) If this package already exists in node_modules, do nothing.(如果此软件包已存在于node_modules中，则什么也不做。) If this package doesn't already exist in the node_modules directory or it is the wrong version, don't add it.(如果此软件包在node_modules目录中尚不存在或版本错误，请不要添加它。) But, show a warning to the user that it wasn't found.(但是，向用户显示未找到的警告。) Extract from https://medium.com/angular-in-depth/npm-peer-dependencies-f843f3ac4e7f(摘自https://medium.com/angular-in-depth/npm-peer-dependencies-f843f3ac4e7f)
