第 6 行中未闭合的 INDENT ( CoffeeScript ) 编译器错误

这是我在 CoffeeScript 中的代码，用于使用 MongoDB 进行简单测试。当我跑步时
咖啡-c UserDataProvider.coffee
我最终得到一个错误 UNCLOSED INDENT ON LINE 6

这是我的代码：

Db   = require('mongodb/db').Db
ObjectID = require('mongodb/bson/bson').ObjectID
Server   = require('mongodb/connection').Server

class UserDataProvider
    constructor = (host,port)->
        this.db = new Db( 'test' , new Server(host ,port,{}))

    getCollection = (callback) ->
        this.db.collection('data',(error,data)->
            if error then callback(error)
            else callback(data)

StackTrace 是：

Error: In UserDataProvider.coffee, unclosed INDENT on line 6
    at Error (unknown source)
    at Rewriter.ensureBalance (/usr/local/lib/node/.npm/coffee-script/1.0.1/package/lib/rewriter.js:283:17)

    at [object Object].<anonymous> (fs.js:86:5)
    at [object Object].emit (events.js:39:17)
    at afterRead (fs.js:843:12)

任何人都可以帮忙吗？

Here is my code in CoffeeScript for a simple test with MongoDB.
When I run
coffee -c UserDataProvider.coffee
I end up with an error UNCLOSED INDENT ON LINE 6

This is my code:

Db   = require('mongodb/db').Db
ObjectID = require('mongodb/bson/bson').ObjectID
Server   = require('mongodb/connection').Server

class UserDataProvider
    constructor = (host,port)->
        this.db = new Db( 'test' , new Server(host ,port,{}))

    getCollection = (callback) ->
        this.db.collection('data',(error,data)->
            if error then callback(error)
            else callback(data)

The StackTrace is:

该行的第一个左括号永远不会关闭：

this.db.collection('data',(error,data) ->

实际上根本不需要它，因此如果您的目的是将“data”作为第一个参数传递，并且 function(error , data) { ... } 作为第二个参数。

The first left parenthesis on this line is never closed:

this.db.collection('data',(error,data) ->

It is actually not needed at all, so you probably want to remove it all together, if your intention is to pass "data" as the first argument and the function(error, data) { ... } as the second argument.
