I followed the instructions here: https://blog.jetbrains.com/webstorm/2016/11/using-flow-in-webstorm/
And what I'm seeing is "Starting Flow Service" with a spinner that never stops. Eventually it fails with a timeout.
In the command line I run `npm run flow` and it works as expected.
This is the path to flow bin that I'm using: "my/project/node_modules/flow-bin/vendor/flow"
