Question

当我发出npm install mongoose --save时，我收到了警告。我在El Capitan 10.11.1，Xcode 7.1.1 Build版本7B1005和npm 2.14.7。虽然一切正常（到目前为止），但我想进一步理解这一点。

对于其他人的某些背景。这个问题源于此：

failing to install mongoose npm

^此问题是错误，因为无法找到libgcc。

在您的情况下，有两个警告。首先是：

npm WARN peerDependencies The peer dependency kerberos@~0.0 included from mongodb-core will no
npm WARN peerDependencies longer be automatically installed to fulfill the peerDependency
npm WARN peerDependencies in npm 3+. Your application will need to depend on it explicitly.

这些是NPM依赖性警告，声明（在这种情况下）mongodb-core取决于kerberos和（可能因为kerberos提供的定制功能对于mongodb-core来说不是完全必需的），它将来不会在npm版本3+中安装mongodb-core的依赖项（如果需要，您将必须明确安装）。

第二个警告是：

warning: implicit declaration of function 'gss_acquire_cred_impersonate_name' is invalid in C99

这意味着，在C99标准中，不允许隐式函数声明（不提供标题签名 - 读取标题和实现文件）。但是，当构建kerberos时，它们已经向C编译器提供了-Wimplicit-function-declaration，告诉它抛出警告而不是错误（因此他们预计会发生这种情况）。
