Cannot read property 'toString' of null, on macOS

After the issue above, I did get another issue after running the command another two times, though not sure in what way it may be related to the original issue.

Same happened to me using 0.5.3 under Ubuntu.
Downgrading to 0.5.2 works fine.

I am getting the same error, when I run command run-rs

After implementing ProtonGustave fix for wrong path, I am getting the following error.

Please let us know how to resolve this. Thanks :)

Should be fixed by #38 in 0.5.4
