Twitter節點未能建立Node.js（npm安裝twitter節點）

Question

我想安裝「Twitter節點」（npm安裝twitter節點）。節點JS的版本.3.2-pre。

當我嘗試安裝時收到跟隨錯誤。有關我可能做錯什麼的想法？看起來像一個非常簡單的安裝給我。我能夠成功安裝插座-io的太...

簡單的解決方案

就從這裏搶吧：

上npm該模塊舊（最後更新8月31日）和由de標記，它編譯自己的base64編碼器，而不是使用Node的內置功能。

要安裝：

1. 下載存檔並解壓縮
2. 光盤放入該文件夾，然後運行npm install .
3. 有一個愉快的一天:)

老答案

安裝運行gcc編譯一個base64模塊依賴於節點Buffer類（C++實現），因爲在3.x中有一些變化，它會爆炸！

Waf: Entering directory `/home/ivo/.local/lib/node/.npm/twitter-node/0.0.2/package/vendor/node-base64/build' 
[1/2] cxx: base64.cc -> build/default/base64_1.o 
../base64.cc: In function ‘v8::Handle<v8::Value> base64_encode_binding(const v8::Arguments&)’: 
../base64.cc:178: error: ‘class node::Buffer’ has no member named ‘data’ 
../base64.cc:178: error: ‘class node::Buffer’ has no member named ‘length’ 
../base64.cc: In function ‘v8::Handle<v8::Value> base64_decode_binding(const v8::Arguments&)’: 
../base64.cc:199: error: ‘class node::Buffer’ has no member named ‘data’ 
../base64.cc:199: error: ‘class node::Buffer’ has no member named ‘length’ 
Waf: Leaving directory `/home/ivo/.local/lib/node/.npm/twitter-node/0.0.2/package/vendor/node-base64/build' 
Build failed: -> task failed (err #1): 
    {task: cxx base64.cc -> base64_1.o} 

This commit刪除了兩個成員，並用靜態內聯方法替換它們。

在.npm/twitter-node/0.0.2/package/vendor/node-base64/base64.cc您需要更換線177/178和198/199它看起來像這樣：

Buffer *buffer = ObjectWrap::Unwrap<Buffer>(args[0]->ToObject()); 
char *str = base64_encode((unsigned char*)buffer->data(), buffer->length(),&len); 

有了這個：

Local<Object> buffer = args[0]->ToObject(); 
char *str = base64_encode((unsigned char*)Buffer::Data(buffer), Buffer::Length(buffer),&len); 

然後運行npm rebuild twitter-node就大功告成了！不要使用安裝，因爲它會重新下載並覆蓋更改。

PS：我不得不使用require('twitter-node@0.0.2')才能導入它，因爲npm沒有在.local/lib/node中創建符號鏈接，但是您可以輕鬆地自行修復它。

更新

我看看模塊，這是熱鬧，他們編一個80KB的lib與改變的Node.js只使用一個使用Base64編碼ONE TIME這是容易出現故障 。

// Returns a Basic Auth header fit for HTTP. 
var basicAuth = function basicAuth(user, pass) { 
    return "Basic " + b64.encode(user + ":" + pass); 
}; 

這不完全一樣的東西和所有其他變化的Node.js不爆炸：

new Buffer(user + ':' + pass).toString('base64')
