eRROR：不可用的软件包“ use-package-”是不可用的（emacs 27.1）

Question

我在配置init.el之后启动emacs时收到此消息：

error: Package ‘use-package-’ is unavailable

eDit

：所以我试图解决这个问题，我了解到，如果这样做：

(require 'package)
(add-to-list 'package-archives
         '("melpa" . "https://melpa.org/packages/") t)
(package-initialize)
(unless package-archive-contents
  (package-refresh-contents))

它起作用！问题是当我尝试安装使用包装时。然后它返回：

我已经抬头看着堆栈和reddit，涉及签名密钥，但没有任何效果。

我的开始是：

(require 'package)

(setq package-enable-at-startup nil)
(setq package-archives '(("elpa"  . "https://elpa.gnu.org/packages/")
                         ("melpa" . "https://melpa.org/packages/")))
(package-initialize)
(package-refresh-contents)  ;; I always ensure package-refresh-contents at start

;; Bootstrap `use-package`
(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))

(require 'use-package)
(setq use-package-always-ensure t)

;; load my-init.org

(custom-set-variables
 ;; custom-set-variables was added by Custom.

(custom-set-faces

 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 )

(put 'downcase-region 'disabled nil)

然后在同一文件夹中，我放置了

init.el

（然后可以使用看起来更好的org模式，并且可以使用tab折叠和脚本的部分展开部分 - 对保持概述非常有用）。 因此，在您的情况下将包含：
