Question

我在emacs中运行python。我已经编写了一些代码，现在我正常使用C-x C-s来保存代码。但是，不是保存，而是在迷你缓冲区中显示autopep8 command not found。我无法保存我的代码。

如何将功能恢复到emacs并保存我的文件？

这是我的init.el

;; init.el --- Emacs configuration

;; INSTALL PACKAGES
;; --------------------------------------

(require 'package)

(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/") t)
(add-to-list 'package-archives '("marmalade" . "https://marmalade-repo.org/packages/"))

(package-initialize)
(when (not package-archive-contents)
  (package-refresh-contents))

(defvar myPackages
  '(better-defaults

(mapc #'(lambda (package)
    (unless (package-installed-p package)
      (package-install package)))

;; BASIC CUSTOMIZATION

(setq inhibit-startup-message t) ;; hide the startup message
(load-theme 'material t) ;; load material theme
(global-linum-mode t) ;; enable line numbers globally

;; PYTHON CONFIGURATION

(elpy-enable)
(elpy-use-ipython)

;; use flycheck not flymake with elpy
(when (require 'flycheck nil t)
  (setq elpy-modules (delq 'elpy-module-flymake elpy-modules))
  (add-hook 'elpy-mode-hook 'flycheck-mode))

;; enable autopep8 formatting on save
(require 'py-autopep8)
(add-hook 'elpy-mode-hook 'py-autopep8-enable-on-save)

;; init.el ends here

安装提供命令autopep8的包或删除行

;; enable autopep8 formatting on save
(require 'py-autopep8)
(add-hook 'elpy-mode-hook 'py-autopep8-enable-on-save)

来自您的配置。可以使用pip或您的软件包管理器进行安装，具体取决于您的系统。在Ubuntu上，这将是

sudo apt-get install python-autopep8

或

pip install autopep8

无法保存文件：“找不到autopep8命令”
