Import Issues - sdk/export/metric/aggregation

[glozow]

I'm trying to use the metrics exporter, but getting an import error:

package go.opentelemetry.io/otel/sdk/export/metric/aggregator: cannot find package "go.opentelemetry.io/otel/sdk/export/metric/aggregator" in any of:
	/usr/local/Cellar/go/1.14.5/libexec/src/go.opentelemetry.io/otel/sdk/export/metric/aggregator (from $GOROOT)
	/Users/gloriazhao/go/src/go.opentelemetry.io/otel/sdk/export/metric/aggregator (from $GOPATH)
	/Users/gloriazhao/stackdriver-sandbox/src/go.opentelemetry.io/otel/sdk/export/metric/aggregator

Not 100% sure what the issue is, but at quick glance it seems like it's trying to import aggregator package but it should be aggregation package. Is there something I can do to fix it?

Oh I see - it looks like it was called aggregator in v0.4.0 but was changed to aggregation recently.
