NPM安装Mongoose Kerberos错误gss_acquire_cred_impersonate_name [英] NPM install Mongoose Kerberos error gss_acquire_cred_impersonate_name

问题描述

发出npm install mongoose --save时，我收到警告.我使用的是El Capitan 10.11.1，Xcode 7.1.1 Build 7B1005和npm 2.14.7.尽管一切正常(到目前为止)，但我想进一步理解这一点.

When I issue a npm install mongoose --save I am receiving a WARN. I am on El Capitan 10.11.1, Xcode 7.1.1 Build version 7B1005, and npm 2.14.7. Although everything is working (so far), I would like to understand this further.

推荐答案

了解其他背景.问题源于此:

For some background for others. This questions stemmed from this:

无法安装猫鼬npm

^此问题是由于找不到libgcc而引发的错误.

^ This question is an error thrown because libgcc cannot be found.

根据您的情况，有两个警告.首先是这样:

In your situation there are two warnings. The first is this:

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依赖项警告，指出(在这种情况下)mongodb-core依赖于kerberos，并且(也许是因为kerberos提供了对mongodb-core起作用并非完全必要的自定义功能)，因此不会安装它作为将来npm 3+版中mongodb-core的随附依赖项(如果需要，则必须显式安装它).

These are NPM dependency warnings that state (in this case) that mongodb-core depends on kerberos and (maybe because kerberos offers custom functionality that is not completely necessary for mongodb-core to function), it will not be installed as an included dependency of mongodb-core in npm version 3+ in the future (and you will have to install it explicitly if you need it).

第二个警告是这样

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-阅读标题和实现文件).但是，在构建kerberos时，他们已将-Wimplicit-function-declaration提供给C编译器，告诉C编译器抛出警告而不是出错(因此，他们希望这样做).

This means that, in the C99 standard, implicit function declarations (without supplying a header signature - read about header and implementation files) are not allowed. However, when kerberos is being built, they have supplied the -Wimplicit-function-declaration to the C compiler that tells it to throw a warning rather than error out (so they are expecting this to happen).
