my $bucketname = "test";
my $bucket = $s3->add_bucket( { bucket => "$bucketname" } )
    or die $s3->err . ": " . $s3->errstr;

运行这个代码给我这个错误。

BucketAlreadyExists: The requested bucket name is not available. The
bucket namespace is shared by all users of the system. Please select a
different name and try again.

桶不存在。我不知道怎么了

谢谢
