Fortunately, you are using emacs 27.0.50, which makes user-level mailcap config easier.

Add the line

image/*; eog %s

to $HOME/.mailcap. Or if you don't have eog, try display or whatever OSX's no-frills image viewer is. For emacs25 and emacs26, refer to FAQ.

thank you for your reply. But I didn't use Linux, I am use Mac, so I can't find eog . and, why there had a file with name .mailcap? I had deleted entire folder of .emacs.d and .emacs, rebuild emacs with only one elpa of ein, but it is still remain the error of ........mailcap.

I found the file filled with win-files exe lines....

image/*; eog %s

I resolved this problem by turn the customize-group-ein-image on. Thanks dickmao for your help very much ! I love EIN! It's so great!

[dickmao]

Your mailcap looks reasonable. Maybe replace eog %s with /usr/bin/qlmanage -p %s. I used to think having images inlined was nice, but I now much prefer displaying them externally. Images, especially big ones, just get in the way of coding/thinking.

Hi, I am on Windows 10 and getting this error. Was not able to find the customize-group-ein-image command, where should I look for it? Is there any other fix? Thank you!

[kindinn]

If you go to customize-group -> ein, search for 'image', it will be listed as Ein:Output Area Inlined Images. Toggling this on worked for me

[mikenlee]

@kindinn answer worked for me. For newbies like me: enter customize-group after you press M-x
