Interpreter error: Could not find module 'Diagrams.Prelude' or 'Diagrams.Backend.Rasterific'

Here is the output I get when I run BlogLiteratelyD test.md on the example from https://www.stackage.org/lts-3.20/package/BlogLiterately-diagrams-0.2.0.1:

Interpreter error:

Even after running stack install diagrams-lib diagrams-rasterific, I still get the same error. How do I make sure that BlogLiteratelyD is loading the correct libraries before running?

How did you install BlogLiteratelyD?

[sid-kap]

stack install BlogLiterately-diagrams (global install)

[byorgey]

And then how do you run it? stack exec BlogLiteratelyD test.md ?

[byorgey]

Running it from a global install is probably not going to work since it needs to have the diagrams packages in the current package DB (so that it can compile diagrams code).

That solves my problem! BlogLiteratelyD test.md did not work, but stack exec BlogLiteratelyD test.md works. Thanks so much for your help!

Great!
