Cannot install extension

I've tried to install many times. But every time got this error.

Active development of this extension has stopped. This means that I probably will not fix issues.
If you want to debug the issue yourself and submit a pull request with a fix, please do.

There are other alternatives to brackets-tabs, namely https://github.com/dnbard/brackets-documents-toolbar

Though this doesn't mean I won't ever commit to this repo again, I might if I have enough spare time.
