如何在Node.js中使用Treetagger進行形態分析

Question

我試圖通過參考https://www.npmjs.org/package/treetagger來運行treetagger，但我得到了下面的錯誤。

TypeError: Object function TreeTagger(options) { 
    events.EventEmitter.call(this); 
    this.options = options || {}; 
    this.encoding = this.options.encoding || 'latin-1'; 
    this.language = this.options.language || 'english'; 
    this.paths = ['.', '/usr/bin', '/usr/local/bin', '/opt/local/bin', 
       '/Applications/bin', '~/bin', '~/Applications/bin']; 
    this.envVars = ["TREETAGGER", "TREETAGGER_HOME"]; 

// Validate the given encoding and language selected 
if (!this.encoding in languages) { 
    throw new Error("Unsupported encoding detected " + this.encoding); 
} 
if (languages[this.encoding].indexOf(this.language) < 0) { 
    throw new Error("Unsupported language detected " + this.language + " for encoding " + this.encoding); 
} 

// Set the appropriate bin path 
if (this.encoding == "latin-1") { 
    this.binPath = 'tree-tagger-' + this.language; 
} 
else { 
    this.binPath = 'tree-tagger-' + this.language + '-' + this.encoding; 
} 

this.binPath = findPath(this.binPath, this.paths, this.envVars); 
} has no method 'tag'

的確，在自述的問題，它應該是：

var TreeTagger = require('treetagger'); 
var tagger = new TreeTagger(); 
tagger.tag("This is a test!", function (err, results) { 
    console.log(results); 
}); 

我發了pull-request圖書館作者解決這個問題。
