GO脚本运行错误亚马逊AWS S3

Question

我目前正在尝试运行以下Golang建设首次在亚马逊的Linux发行版：

README这里：

go get github.com/adammck/s3-graphite 
cd $GOPATH/adammck/s3-graphite 
go build 

在此之后，我把我的变量在我的.bashrc文件如下图所示：

# AWS keys with read access to the bucket 
export AWS_ACCESS_KEY_ID=xxxxxxxxxx 
export AWS_SECRET_ACCESS_KEY=yyyyyyyyyy 
export AWS_REGION=us-east-1 

# the bucket to watch 
export S3_BUCKET=my-bucket 
export S3_PREFIX=dir/subdir 

# the server to send metrics to 
export GRAPHITE_ADDRESS=metrics.example.com 
export GRAPHITE_PREFIX=s3-count.my-bucket.dir.subdir 

设置我GOPATH以下几点：

export GOPATH="$HOME/work/" 

我用cd命令进入目录运行去构建它的工作原理像它应该，但是当我去跑旅途生成后如下：

。/S3石墨

我得到以下错误：

这里是我的GOPATH：

$GOPATH 
-bash: /home/ec2-user/work/: Is a directory 

这里是我的目录，我执行S3-石墨：

/home/ec2-user/work/src/github.com/adammck/s3-graphite 

EDIT（与你的答案项更新：

Answer 1

似乎有是几件事情怎么回事。需要检查的一件事是，在您设置环境变量后，您实际上正在采购您的.bashrc文件。您应该能够运行env命令并在当前shell中查看您的AWS密钥，S3配置和石墨设置。

我看到的第二个问题是您使用的库自去年以来没有更新过。据我所知，去年的AWS SDK for Go发生了很大变化。应用程序输出中的“恐慌：”行提示了该问题。

panic: runtime error: invalid memory address or nil pointer dereference

好像nil被传递的地方它不应该是。再往下恐慌输出，你可以看到的goroutine 1堆栈跟踪说：

github.com/aws/aws-sdk-go/service/s3.New(0x0, 0x0, 0x0, 0x0, 0x0, 0x3f) 
    /home/ec2-user/work/src/github.com/aws/aws-sdk-go/service/s3/service.go:41 +0x76 
main.NewS3(0x7ffc202bef6e, 0x1b, 0x7ffc202be684, 0x9, 0x1, 0x0, 0x0) 
    /home/ec2-user/work/src/github.com/adammck/s3-graphite/s3.go:20 +0x66 

从这里就可以看出，NewS3方法被调用上的S3-石墨库s3.go文件的第20行。然后它转到aws-sdk-go库并尝试创建一个新的S3客户端。使用以下参数：

s3.New(0x0, 0x0, 0x0, 0x0, 0x0, 0x3f)

我最好的家伙，你的配置不导出到环境中，你正在运行的可执行文件，或S3石墨库需要更新了最新的工作AWS-SDK -go版本。
