Error when opening ansi-term in zsh

[domi91c]

Description

When I open ansi-term, I get these errors:
error in process filter: face-attribute: Invalid face: unspecified
error in process filter: Invalid face: unspecified

Instead of my zsh prompt, I see some random letters and I'm unable to type anything. It was working at one point in terminal Emacs, but now it's not working in either the GUI or the terminal.

Seeing the same thing with fish. Bash works.

[domi91c]

What reproduction steps are needed for this?

[StreakyCobra]

What command do you use for running the ansi-term, and your ZSH prompt, or a fish config… something allowing to reproduce, because even with zsh and the agnoster prompt I can't reproduce :-(

[sooheon]

I have found the source of the problem, at least for me. Some of the themes installed by themes-megapack must touch custom-set-faces, there were various term/ansi-term colors set in there which caused the errors. Deleting these customizations resolved the issue for me.

[syohex]

This issue is similar to bbatsov/zenburn-emacs#87. Your theme has same issue same as it(zenburn already fixed).

@portOdin Which theme did you use ?

[t3chnoboy]

I have the same issue with fish. It was working before.
Now I get those errors in terminal and gui emacs regardless of the emacs and fish theme 😞

Im on 0.200.4@25.1.1 and I get error in process filter: face-attribute: Invalid face: unspecified error in process filter: Invalid face: unspecified when opening ansi-term.
Nothing new has changed over my side.
Everything was fine a couple of days ago

[erebe]

Same as @brenogil. ansi-term was working fine with zsh previously, but after an update I cannot open it anymore

[brenogil]

After being unable to find/craft a solution after some poking around, I deleted my .spacemacs and started another from scratch. All is fine now.

[erebe]

@brenogil I can confirm
I upgraded all packages (SPC T m -> options -> manage packages -> U -> x) and now I can spawn a zsh shell correctly

[d12frosted]

Ok, so it looks like you just need to update all packages (might be upstream issue with theme or anything else) and Spacemacs.

Closing this for now. Let us know if it's and issue.

I had the same issue. What I did I commented out a line in spacemacs file that was setting variable ansi-term-color-vector:

;; Do not write anything past this comment. This is where Emacs will
;; auto-generate custom variable definitions.
(custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 '(ansi-color-faces-vector
   [default bold shadow italic underline bold bold-italic bold])
 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; '(ansi-term-color-vector
 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;   [unspecified "#FFFFFF" "#d15120" "#5f9411" "#d2ad00" "#6b82a7" "#a66bab" "#6b82a7" "#505050"] t)

This is auto generated by custom so I'm not sure if after some time this setting will be added again.

In the meantime this seems like a related problem: tinted-theming/base16-emacs#4

@asok Thank you!!!
It resolved the issue for me ☺️

@Lord-Guckavin Sorry but we aren't a dating portal.

[asok]

@Lord-Guckavin I'd prefer if you just buy a beer.

I had this problem this week; not resolved. Thanks @asok
