polyglot demo: No such file or directory: README.md

[xuchunyang]

I'm following the Get Started guide. polyglot demo fails. I try reinstalling polyglot but it does not help, there still is no README.md. I am not not sure if I misunderstand anything.

I'm having the same problem on Windows 10. It expects the README to be at path C:\Users\y0hy0h\AppData\Roaming\Racket\7.6\pkgs\polyglot-lib\polyglot\README.md, but there is no such file. I couldn't find it in the polyglot or polyglot-doc folders either.

I assume that it is somehow not included anymore.

As a workaround you can create the README at that location, copying the contents, and then run raco polyglot demo again. On Windows, I had to use a cmd as Administrator, because otherwise it complained about not being allowed to create links. But it has worked that way.

I suspect this is due to a missing copy-shared-files binding in info.rkt, but I need to confirm that. Interesting that this doesn't seem to happen on Linux systems. Will have addressed by 2.9.

Another workaround: copy the README.md into an assets directory of your own project and run it using the default config.

245021b28c353e3f898c36de2bbeaa3d3481388b should address this. Leaving issue open in case problem reproduces after the catalog updates.
