不能使用err（类型错误）作为goreq类型。返回参数中的错误

I am trying to return two values (result and error) from a method but I get this

cannot use err (type error) as type goreq.Error in return argument

my code

package components

import (
    goreq "github.com/franela/goreq"
    "time"
)

var UserAgent string = "..."

func Get(url string) (*goreq.Response, goreq.Error) {
    goreq.SetConnectTimeout(15 * time.Second)
    res, err := goreq.Request{
        Uri: url,
        UserAgent: UserAgent,
        Timeout: 5 * time.Second,
    }.Do()

    return res, err
}

Do() returns type error, not goreq.Error. Change your second return type to error instead of goreq.Error.
