[MuhmdRaouf]

Describe the bug
Trying to install emacs ver 27 with the following options, but it always gave me this error and I don't know what to do, also Cocoa should be enabled by default.

Command used to install emacs-plus

$ brew install emacs-plus --HEAD --with-emacs-27-branch --with-dbus --with-jansson --with-modern-icon --without-spacemacs-icon --with-xwidgets --with-x11

Also when I installed it using the following but Emacs.app didn't exist and i have to use emacs from terminal now with the following command:

==> Caveats
Emacs.app was installed to:
  /usr/local/opt/emacs-plus

To link the application to default Homebrew App location:
  ln -s /usr/local/opt/emacs-plus/Emacs.app /Applications

--natural-title-bar option was removed from this formula, in order to
  duplicate its effect add following line to your init.el file
  (add-to-list 'default-frame-alist '(ns-transparent-titlebar . t))
  (add-to-list 'default-frame-alist '(ns-appearance . dark))
or:
  (add-to-list 'default-frame-alist '(ns-transparent-titlebar . t))
  (add-to-list 'default-frame-alist '(ns-appearance . light))


To have launchd start d12frosted/emacs-plus/emacs-plus now and restart at login:
  brew services start d12frosted/emacs-plus/emacs-plus
Or, if you don't want/need a background service you can just run:
  emacs

Hi @MuhmdRaouf

Well, the error says it all.

Error: --with-xwidgets is supported only on cocoa via xwidget webkit

Which means that you need to install with cocoa (e.g. don't use --with-x11). Maybe it's not that clear after all 🤔

Also when I installed it using the following but Emacs.app didn't exist and i have to use emacs from terminal now with the following command:

Not sure which command exactly you use. But as caveats sections says, if you want to install Emacs.app to /Applications folder, you need to link it using ln -s. Cask builds are not supported (see #41).

@d12frosted Ouch the message tells me what I need but I didn't realize it, sorry but I think it's not really clear, at least for me, But Thanks so much for your reply mate.

secondly the command I used
brew install emacs-plus --with-emacs-27-branch --with-jansson --with-modern-icon --with-x11 --without-spacemacs-icon --HEAD

and I did link it as the logs told me like the following
ln -s /usr/local/opt/emacs-plus/Emacs.app /Applications

yet the link was broken and I went into this path ln -s /usr/local/opt/emacs-plus
and didn't found the Emacs.app which is very strange to me.

PS. removing the flag --with-x11 solve the second issue and Emacs.app shows up.

will try to remove it also for the first issue and see how it goes.

Ouch the message tells me what I need but I didn't realize it, sorry but I think it's not really clear, at least for me,

Yeah... Thanks to you I also realized how unclear it might be.

Yeah, x11 means that you don't want cocoa application, which means, that you won't get Emacs.app. Maybe it also needs to be documented.

[MuhmdRaouf]

I can confirm that removing --with-x11 solves both issues for me, Thanks a lot @d12frosted 😄

[d12frosted]

No problem! Let me know if you have any other issues!
