@othiym23 CI has passed now, related PR: othiym23/async-listener#129

Please if ok, publish a new version, thank you very much!

[othiym23]

Why is this PR necessary? The current semver range (async-listener@^0.6.0) will automatically pick up async-listener@0.6.9 upon a fresh install. Is there a particular reason to pin the dependency?

Aha, thank you for your remind: it does't need to publish a new version.
It looks like only ci test need this PR.

@othiym23 Hi, I think this PR should be merged. So other contributor can rely on CI test.

If any thoughts, expect reply~ ^_^
