Answer 1

bcrypt 需要本地构建。如果您不习惯使用 c++ 编译器构建它，我建议您看一下 bcrypt-nodejs 模块。它基本上更容易做同样的事情:

var bcrypt = require('bcrypt-nodejs');

示例:

bcrypt.genSalt(10, function(err, salt) {
      if (err) return err;

      bcrypt.hash(attrs.password, salt, null, function(err, hash) {
        attrs.password = hash;            
      });
    });
