TypeError: The "digest" argument is required and must not be undefined

Question

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

我做了很多不同的事情，比如清除 npm 缓存，使用 npm 重新安装等。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

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 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

通过进一步调查，您还可以看到节点 v6.0 中需要摘要参数。

之前的默认值好像是'sha1'。

Answer 2

这也可能是由于节点版本错误引起的/运行正在使用的节点版本不支持调用的版本

我的经验：我的团队有一个应用程序需要 Node 6.10.0。有时我忘记切换到这个版本的节点和运行 8.6.0 下的最新代码，我收到同样的错误。一旦我切换回 6.10.0，该网站将允许我登录。

（我可以看到已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，以防它能帮助那里的人！）
