Rendering a file does not work #173

Hello,

I'm following the beginner's tutorial for Pollen and I'm getting the following error when attempting to render the 'hello world' exercise. I performed the standard installation, and ensured that Pollen was properly installed using raco pollen test.

This issue appears similar to https://github.com/mbutterick/pollen/issues/100

If I can provide any additional information, please let me know. Thank you.

Strictly speaking the tutorial asks for the command

raco pollen render hello.text.pp

which did work. But I agree that your version:

raco pollen render ./hello.text.pp

should not be broken.

I really appreciate your swift response, thank you.

I originally attempted it as-written, and I've included the output below. If I can provide any additional information, please let me know.

Best,
Lorenzo

For completeness, here is the input file:

I’m afraid I can’t reproduce this error. Is there anything unusual about how your home directory is set up? The fact that similar errors happened in two different functions suggests that Racket is getting confused about how to resolve the ~ in the path (though usually it doesn’t, hence my question)

Using the absolute path I get the same error, which I've included below. I'll try to troubleshoot this later and open a PR/Issue if appropriate.

Thank you

Now I’m more confused. What OS is this? Nothing unusual in the /home/ directory path, like symlinks or funny mount points, etc? (Those should work, but I’m trying to identify some combination of factors that would let me reproduce the error)

Thanks for your assistance with this. I recently reinstalled everything and it appears to be functioning as expected.

Take care,
