类型错误：“digest”参数是必需的，并且不能是未定义的

我在通过注册简单的平均应用程序时遇到主题错误http://localhost:3000/auth/register http://localhost:3000/auth/register，我只是使用创建的mean init命令。pbkdf2 or crypto正在生成错误，但我不知道在哪里寻找它。

我做了很多不同的事情，比如清除 npm 缓存、使用 npm 安装等。请帮助我。以下是更多信息。

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

代码为model.UserSchema.methods.hashPassword(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 http://localhost:3000/api/register它产生500 Internal Server Error.

Firefox 显示以下响应：

Per the crypto.pbkdf2Sync方法你错过了最后一个参数digest，从而显示错误。

加密.pbkdf2 https://nodejs.org/api/crypto.html#crypto_crypto_pbkdf2sync_password_salt_iterations_keylen_digest

另外，通过进一步调查，您可以发现 Node v6.0 中需要摘要参数。

之前的默认好像是'sha1'.
