无法在emacs中安装一些melpa软件包

Question

我只是在试用emacs (来自vim)。

我已经运行了M-x package-refresh-contents多次，但仍然，许多软件包，我想要安装没有列出。例如，走模式

知道我在哪里搞砸了吗？谢谢!

根据您的描述，MELPA包似乎根本没有加载。

因此，首先，检查什么C-h v package-archives输出。它在返回列表中输出“melpa”吗？

您还可以运行M-x package-list-packages，并在列出的结果中查看是否有任何melpa存档包。

在我的配置中，我以这种方式显式地设置了包存档：

(require 'package)

(setq package-archives
      '(("gnu" . "https://elpa.gnu.org/packages/")
        ("gnu-devel" . "https://elpa.gnu.org/devel/")
        ("nongnu" . "https://elpa.nongnu.org/nongnu/")
        ("melpa" . "https://melpa.org/packages/")))

同时，自从Emacs 27.1 在你的init文件中。

因此，您应该能够安全地删除(package-initialize)调用或有条件地使用它，例如：

(when (< emacs-major-version 27)
  (package-initialize))
