ImageIO missing

[roflmaostc]

Hi,

sometimes I get this error.
Should we add ImageIO as dependency or how do we solve that?

Failed to show value:

ArgumentError: Package ImageIO [82e4d734-157c-48bb-816b-45c225c6df19] is required but does not seem to be installed:

- Run `Pkg.instantiate()` to install all recorded dependencies.

It should be in your own environment. FileIO is designed to know which packages to use, but it's up to the user to add them to the environment. If you can suggest a clearer error, I'm happy to hear it.

[roflmaostc]

So in my case I just put ImageShow as package and then it complains about the ImageIO issue. For example in a Pluto notebook

[timholy]

Yes. The issue seems to be that Pluto is triggering display. For display it seems it needs to save an image to file (possibly for the interaction with the browser?) but you didn't add an IO package to your environment. FileIO is designed to be generic and allow the user to choose which IO package to use. Consequently, I'd interpret this as "user error" but the error message may be too unclear to make that interpretation valid. I'd be grateful if you could suggest ways we could make this clearer.
