我按照'Watson Quickstart for Node.js'找到here，但我在使用npm命令安裝Watson Developer Cloud Node.js包裝程序包時遇到問題他們提供。使用npm安裝watson-developer-cloud時出錯
下面是輸出： cmd output after npm command
之後，沒有文件出現在其中運行命令的目錄。有沒有人有關於如何安裝Watson Developer Cloud包裝器以開始通過Bluemix開發通過Node.js開發Watson應用程序的任何建議？
好的，所以文檔頁面有很多問題。我將它們與解決方案一起列在下面。在解決以下缺點之後，我能夠得到該示例。
該示例中的源代碼使用完全過時的請求參數 - 請參閱下面更新的源代碼。
var watson = require（'watson-developer-cloud'）;
var machine_translation = watson.language_translation({
username: 'user_name',
password: 'password',
version: 'v2'
});
//the attributes from and to in the example provided are actually replaced by source and target
machine_translation.translate({
text: 'A sentence must have a verb', source : 'enus', target: 'eses' },
function (err, response) {
if (err)
console.log('error:', err);
else
console.log(JSON.stringify(response, null, 2));
});
希望這能解決你的問題。當然，示例中顯示的代碼只是一個入門代碼 - 如果您想開發複雜的應用程序，那麼您需要引入其他依賴項，例如expressjs，jade等，然後明確實現這些。

我已打開一個工作項目以請求更新文檔。 –
彼得，
故宮命令應該已經創建了一個包含沃森包裝的API目錄nodes_module。 您仍然需要編寫一個主要的Node.js文件來調用API。 下面的例子是使用語言翻譯沃森服務Node.js的文件：
var express = require('express');
var app = express();
app.get('/', function (req, res) {
res.send('Hello World!');
});
var watson = require('watson-developer-cloud');
var language_translation = watson.language_translation({
username: '<username>',
password: '<password>',
version: 'v2'
});
language_translation.translate({
text: 'A sentence must have a verb', source : 'en', target: 'es' },
function (err, translation) {
if (err)
console.log('error:', err);
else
console.log(JSON.stringify(translation, null, 2));
});
language_translation.identify({
text: 'The language translation service takes text input and identifies the language used.' },
function (err, language) {
if (err)
console.log('error:', err);
else
console.log(JSON.stringify(language, null, 2));
});
var server = app.listen(3000, function() {
var host = server.address().address;
var port = server.address().port;
console.log('Example app listening at http://%s:%s', host, port);
});
它需要快遞，所以你必須先安裝快車和運行Node.js應用程式（假設你保存上述文件作爲app.js，還需要進入屈臣氏的服務用戶名和密碼在文章中解釋你是以下）：
npm install express
node app.js
輸出與此類似：
Example app listening at http://:::3000

Peter，
您所指的頁面版本是在三個多月前完全重寫的。重寫應該解決您遇到的問題。這似乎是可在同一網址：
我不知道爲什麼你看到這樣一個老版本的頁面。也許這是你的緩存中陳舊的版本？請嘗試刷新頁面，看看是否有幫助。
我也跟着OP粘貼的頁面，確實那裏的文檔已經過時了。另外，這是我第一次使用語言翻譯服務。也許這是一個陳舊的環節，需要清理。謝謝。 –
請參閱我的答案以獲取完整的解決方案 –
