It seems that all files has the execute permission already:

This PR also fixing the build by updating npm at the beginning.

Thanks! Can you confirm the build is working properly by scaffolding to another repo - and enabling travis there , as the travis on this repo just checks the generator itself.

btw, I believe that now we have in Gizra a travis installation that runs using Docker. Maybe worth doing the switch of this generator as-well (can be a follow up of course)

I see also an error when running drush @site runserver 127.0.0.1:8080 & since it's not defined anywhere. Bekitzur -- need to run it and see it works ;)

Basically I've found the issue about the files stats.

          self.fs.write(newFileName, newContents);

doesn't pass the stat of the file.

In a newer version of mem-fs-editor there is an option to pass a stat as well, but I got some other issues on the way, probably because all versions here are not updated.

We probably need to do a lot of refactoring.

I was thinking of adding a bash command for that chmod +x scripts/... but this is only a workaround, it's better to preserve the original stat for each file.
