Cannot install eglot

[david-vicente]

Directions to reproduce

Starting with a clean init file

(require 'package)
(setq package-enable-at-startup nil)

(setq straight-repository-branch "develop")
(defvar bootstrap-version)
(let ((bootstrap-file
       (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
      (bootstrap-version 5))
  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))

(straight-use-package 'use-package)

(eval-when-compile
  (require 'use-package))


(use-package eglot
  :straight t
  :defer t
)

Try running M-x straight-pull-package RET project RET. Perhaps there is a bug in that version of the dependency project.

I tried that command and after that evaluating

(use-package eglot
  :straight t
)

and got this

I experience same issue on OSX. Any thoughts about that? Maybe some workaround?

[raxod502]

This is a bug in Emacs, introduced by https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=b63c5a7efc89c23230f53a346e29e72a9b4faafc, which causes project.el to depend on a later version of Emacs than 26.3 despite the following comment:

;; Package-Requires: ((emacs "26.3"))

;; This is a GNU ELPA :core package.  Avoid using functionality that
;; not compatible with the version of Emacs recorded above.

You should be able to work around the problem by adding project to straight-built-in-pseudo-packages before loading anything that declares a dependency on project.

Just chiming in to say I experienced this as well, but it works with the newly released Emacs 27.1

Would recommend upgrading if you want to use eglot or lsp anyway since it adds the native json code

[david-vicente]

Stopped happening since I upgraded to 27.1
