Twitter节点未能建立Node.js（npm安装twitter节点）

Question

我想安装“Twitter节点”（npm安装twitter节点）。节点JS的版本.3.2-pre。

当我尝试安装时收到跟随错误。有关我可能做错什么的想法？看起来像一个非常简单的安装给我。我能够成功安装插座-io的太...

简单的解决方案

就从这里抢吧：
https://github.com/patmcnally/twitter-node

上npm该模块旧（最后更新8月31日）和由de标记，它编译自己的base64编码器，而不是使用Node的内置功能。

要安装：

1. 下载存档并解压缩
2. 光盘放入该文件夹，然后运行npm install .
3. 有一个愉快的一天:)

老答案

安装运行gcc编译一个base64模块依赖于节点Buffer类（C++实现），因为在3.x中有一些变化，它会爆炸！

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: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删除了两个成员，并用静态内联方法替换它们。

在.npm/twitter-node/0.0.2/package/vendor/node-base64/base64.cc您需要更换线177/178和198/199它看起来像这样：

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

有了这个：

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

然后运行npm rebuild twitter-node就大功告成了！不要使用安装，因为它会重新下载并覆盖更改。

PS：我不得不使用require('twitter-node@0.0.2')才能导入它，因为npm没有在.local/lib/node中创建符号链接，但是您可以轻松地自行修复它。

更新

我看看模块，这是热闹，他们编一个80KB的lib与改变的Node.js只使用一个使用Base64编码ONE TIME这是容易出现故障 。

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

这不完全一样的东西和所有其他变化的Node.js不爆炸：

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