TypeError：“摘要”参数是必需的，不能是未定义的
我通过http：// localhost：3000 / auth / register注册一个简单的Mean Application时遇到了主题错误，我只是使用mean init命令创build的。 pbkdf2或crypto正在产生的错误，我不知道在哪里寻找它。
我做了很多不同的事情，如清除npmcaching，重新安装使用npm等，请帮助我。 以下是一些更多的信息。
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 ，它会生成500 Internal Server Error 。
Firefox正在显示以下响应：

根据crypto.pbkdf2Sync方法，你缺less最后一个摘要的参数，因此显示的错误。
https://nodejs.org/api/crypto.html#crypto_crypto_pbkdf2sync_password_salt_iterations_keylen_digest
另外，通过进一步调查，您可以看到在节点v 6.0中需要摘要参数。
以前的默认似乎是'sha1'。
这也可能是由于节点版本错误/运行的版本具有在您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。 有时我忘记切换到这个版本的节点，并运行8.6.0下的最新代码，并收到相同的错误。 只要我换回到6.10.0的网站将允许我login。
（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，以防止有人在那里！）
