When I open a sws file in sagemath 7.5.1, I get the following error:

RuntimeError: no available port.

How to repair it.

By the way, is there some easily method to convert sws files to ipynb files.

I think to answer the first question we'll need more information about how you are using Sage, what you downloaded, how you try to open them, etc.

My OS is macOS Sierra 10.12.3

Sagemath installed from pre-built binarie:

The web browse can not be open whether click sws files or run " /Applications/"

But the jupyter notebook work well.

So you mean when you double click the app, it doesn't start?

I would actually try restarting your computer first to make sure there aren't any stray sagenb processes causing this problem as well, though that usually manifests with a different error message.

The answer to the second question is yes: the command

sage -n export --list

displays the list of of your sws files. Then to convert, say, the one listed as admin:10, run

sage -n export --ipynb=Output.ipynb admin:10

See sage -n --help for further details. In SageMath 8.0 (arriving just after 7.6), some automatic conversion will be implemented.
