如何更改导入文件？

Question

I have the following function in golang:

import (
    "github.com/aws/aws-sdk-go/service/iam"
    "github.com/aws/aws-sdk-go/aws/session"
    "fmt"
)
func NewIAM() *SphinxIAM {
//  awsConfig := aws.NewConfig()
    sess, err := session.NewSession()
    if err != nil {
        fmt.Println("Failed to create session,", err)
        return nil
    }
    session := &SphinxIAM{iam: iam.New(sess)}
    return session
}

Now, I am getting the following error when I run this:

cannot use sess (type *session.Session) as type "github.com/aws/aws-sdk-go/aws/client".ConfigProvider in argument to iam.New:
    *session.Session does not implement "github.com/aws/aws-sdk-go/aws/client".ConfigProvider (wrong type for ClientConfig method)
        have ClientConfig(string, ...*"stash/cloud/sphinx/vendor/github.com/aws/aws-sdk-go/aws".Config) "stash/cloud/sphinx/vendor/github.com/aws/aws-sdk-go/aws/client".Config
        want ClientConfig(string, ...*"github.com/aws/aws-sdk-go/aws".Config) "github.com/aws/aws-sdk-go/aws/client".Config

I have to change the method getting imported but how do I exactly do that?

Thanks!

The problem here is that your github.com/aws/aws-sdk-go/aws/session package is vendored, it is loaded from the folder stash/cloud/sphinx/vendor/github.com/aws/aws-sdk-go/aws.

But the function you want to pass it: iam.New() is not vendored, it does not come from the same vendor folder (stash/cloud/sphinx/vendor/xxx) but it comes directly from github.com/aws/aws-sdk-go/service/iam.

Either put both packages under the same vendor folder, or none. It is possible that one of your dependency tool does this, (e.g. glide), in which case you should instruct your tool to handle both as vendored.
