BUG: TypeError: bin_path is not a function

[blacksun1]

Hello,

I have the following code:

const MongodbPrebuilt = require("mongodb-prebuilt");

function logs_callback(buffer) {
    console.log("log message:", buffer.toString());
}

MongodbPrebuilt.start_server({
  version: "2.6.8",
  logs_callback: logs_callback,
  args: {
    port: 9999,
    quiet: false,
    verbose: true
  }
}, function(err) {
  if (err) {
    console.log("mongod didnt start:", err);
    return;
  }

  console.log("mongod is started");
});

running on node version v4.4.7 on MacOSX 10.11.6. It is giving me the following error:

> sudo DEBUG='mongodb mongodb-prebuilt' node server.js

This is invalid javascript

function bin_path() { /*...*/ }

function install(version, callback) {
    var bin_path = bin_path(version);
    /*...*/
}

As soon as you declare var bin_path, the value bin_path is undefined. So this function will always fail.

So why did it ever work? Because mongodb-prebuilt as a postinstall script that manually runs install.js.

You'll only run into this bug:

• You call start_server with a non-default version
• You change your project path (the install script caches some file references using absolute paths)

TL;DR: reinstall mongodb-prebuilt, and you should be fine

bin_path is now deprecated with latest release.
