未安装Kerberos库

标签： node.js mongodb kerberos

我有一个简单的项目来测试Kerberos身份验证。这是一台Windows机器。 在我的package.json中：

"dependencies": {
    "kerberos": "^0.0.24",
    "mongodb": "^3.0.10"
  }

连接网址：

const url = 'mongodb://userxxx%40XXXXX.XXXXX.COM:Password01@servername:27017/?authMechanism=GSSAPI&authSource=%24external&ssl=true';

但是，当我尝试连接代码时：

MongoClient.connect(url, (err, client) => { 
  if (err) {
    console.error(err);

我收到错误消息Error: Kerberos library is not installed

我尝试了nuking node_modules并重新安装所有内容。我尝试在全球和本地安装kerberos模块。每次都有相同的一致结果。寻找见解。谢谢。

编辑： 安装/编译期间没有错误：

$ yarn add mongodb kerberos

答案 0 :(得分：0)

经过一番挖掘后，我在mongodb-core / lib / auth / sspi.js中找到了这个：

try {
  Kerberos = require_optional('kerberos').Kerberos;
  // Authentication process for Mongo
  MongoAuthProcess = require_optional('kerberos').processes.MongoAuthProcess;
} catch (err) {} // eslint-disable-line

问题是它默默地捕获错误并且不报告任何内容。将console.log(err)放入catch后，我看到以下错误：

Error: optional dependency [kerberos] found but version [0.0.24] did not satisfy constraint [^0.0.23]
sspi.js:34
code:"OPTIONAL_MODULE_NOT_FOUND"
message:"optional dependency [kerberos] found but version [0.0.24] did not satisfy constraint [^0.0.23]"

__proto__:Object {constructor: , name: "Error", message: "", …}

将kerberos降级到版本0.0.23解决了这个问题。
