Emacs shell无法识别python命令

Question

我一直在尝试用emacs编写一些python代码，但是emacs的shell不能编译我的代码。它一直显示此错误：'python‘未被识别为内部或外部命令、可操作程序或批处理文件。’我已经将Python路径添加到系统变量中，所以它可以在命令提示符下正常运行python，但不能在emacs shell中正常运行这是我的init.dl文件

(require 'package)

;; Adds the Melpa archive to the list of available repositories
(add-to-list 'package-archives
             '("melpa" . "http://melpa.org/packages/") t)

;; Initializes the package infrastructure
(package-initialize)

;; If there are no archived package contents, refresh them
(when (not package-archive-contents)
  (package-refresh-contents))

;; Installs packages
;;
;; myPackages contains a list of package names
(defvar myPackages
  '(better-defaults    ;; Set up some better Emacs defaults
    elpy               ;;Emacs lisp python environment
    material-theme                  ;; Theme
    )
  )

;; Scans the list in myPackages
;; If the package listed is not already installed, install it
(mapc #'(lambda (package)
          (unless (package-installed-p package)
            (package-install package)))
      myPackages)

这个包将帮助您：exec-path-from-shell。

您可以通过Emacs内置的包管理器Melpa安装它，方法是运行以下命令

M-x package-install RET exec-path-from-shell RET

然后，将以下行放入您的init file并重新启动Emacs：

(exec-path-from-shell-initialize)
