在ubuntu 14.04 VPS上執行.js文件錯誤

Question

您好，當我嘗試在ubuntu上運行我的sell.js javascript時，出現以下錯誤：

節點sell.js

socket timed out
socket closed
connecting to 72.165.61.175:27018

encrypt request

/var/www/bot/node_modules/steam/lib/steam_client.js:150
  var cryptedSessKey = require('crypto').publicEncrypt(fs.readFileSync(__dirna
                                         ^
TypeError: Object #<Object> has no method 'publicEncrypt'

    at Connection.Readable.push (_stream_readable.js:128:10)
    at TCP.onread (net.js:529:21)

/var/www/bot/node_modules/steam/lib/steam_client.js中的代碼：

handlers[EMsg.ChannelEncryptRequest] = function(data) {
  this._connection.setTimeout(0);

  this.emit('debug', 'encrypt request');

  this._tempSessionKey = require('crypto').randomBytes(32);
  var cryptedSessKey = require('crypto').publicEncrypt(fs.readFileSync(__dirname + '/public.pub'), this._tempSessionKey);
  var keyCrc = require('buffer-crc32').signed(cryptedSessKey);

  var encResp = new schema.MsgChannelEncryptResponse().encode();
  var body = new ByteBuffer(encResp.limit + 128 + 4 + 4, ByteBuffer.LITTLE_ENDIAN);

  body.append(encResp);
  body.append(cryptedSessKey);
  body.writeInt32(keyCrc);
  body.writeUint32(0);

  this._send(EMsg.ChannelEncryptResponse, body.flip());
};

我做了npm install --save crypto，但是它不起作用，我總是收到這個錯誤..如果有人知道如何解決這個問題，請告訴我。

根據反饋和測試，當前的問題是Ubuntu 14.04存儲庫具有Node 0.10分支。 在此分支中，crypto.publicEncrypt API函數不存在。 您必須安裝4.x或5.x版本的node.js才能使用這些功能。

https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions

對於Node.js v4：

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs

另外，對於Node.js v5：

curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -
sudo apt-get install -y nodejs

可選 ：安裝構建工具

要從npm編譯並安裝本機插件，您可能還需要安裝構建工具：

sudo apt-get install -y build-essential
