TypeError：“digest”参数是必需的，不能是未定义的

Question

我通过http://localhost:3000/auth/register注册一个简单的平均应用程序时遇到了主题错误，我只是使用mean init命令创建的。 pbkdf2或crypto产生错误，我不知道在哪里寻找它。

我做了很多不同的事情，比如清晰的npm缓存，使用npm等安装。请帮帮我。以下是一些更多信息。

Mean --version: 0.12.15
npm --version: 5.0.3
node --version: v8.1.0
bower --version: 1.8.0
gulp --version: CLI and Local: 3.9.1

model.UserSchema.methods.hashPassword的代码（D：\ Projects \ Mean \ CampaignBuilder \ node_modules \ meanio-users \ server \ models \ user.js）

/**
 * Hash password
 *
 * @param {String} password
 * @return {String}
 * @api public
 */
UserSchema.methods.hashPassword = function(password) {
  if (!password || !this.salt) return '';
  var salt = new Buffer(this.salt, 'base64');
  return crypto.pbkdf2Sync(password, salt, 10000, 64).toString('base64');
};

注册页面调用http://localhost:3000/api/register并生成500 Internal Server Error。

Firefox正在显示以下响应：

Answer 1

根据crypto.pbkdf2Sync方法，您缺少最后一个参数digest，因此显示错误。

crypto.pbkdf2

此外，通过进一步调查，您可以看到节点v6.0中需要摘要参数。

以前的默认似乎是'sha1'。

Answer 2

这也可能是由于错误版本的节点/运行的版本具有在您拥有活动的节点版本中不支持的调用

我的经验：我的团队有一个需要Node 6.10.0的应用程序。有时我忘记切换到此版本的节点并运行8.6.0下的最新代码，我收到相同的错误。一旦我换回6.10.0，网站就会允许我登录。

（我可以看到接受的答案也提到了这一点，但我想添加一个更明显的答案，以防有人帮助那里！）
