Emacs Elpy找不到包裹

Question

首先，如果我的问题很愚蠢，请原谅。然而，我不能解决我所遇到的问题。

我将在Python上开始一个项目，并希望使用Emacs作为默认编辑器。我想首先建立我的环境，以便有效地工作。在以前的项目中，我使用了现有的环境，但希望在本地机器上拥有自己的环境。我在MacOS10.12.6上。

我从下载Python2.7.10和最新的Emacs开始--版本26.1。我读到Elpy是Python最好的开发环境之一，并下载了它。

这是我的.emacs文件。它位于我的主目录中(肯定不是最优的)。

;; init.el --- Emacs configuration

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

(require 'package)

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

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

(defvar myPackages
  '(better-defaults
     elpy ;; add elpy package
     material-theme))

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

;; 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


;; init.el ends here
(custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 '(package-selected-packages
   (quote
    (python-environment elpygen py-autopep8 material-theme elpy better- 
   defaults))))
(custom-set-faces
 ;; custom-set-faces was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 )

(elpy-enable)

关于Emacs，我想让Elpy。查看配置，我得到以下信息

Virtualenv........: None
RPC Python........: 2.7.10 (/usr/bin/python)
Interactive Python: python (/usr/bin/python)
Emacs.............: 26.1
Elpy..............: 1.24.0
Jedi..............: Not found
Rope..............: Not found
Autopep8..........: Not found
Yapf..............: Not found
Black.............: Not found
Syntax checker....: Not found (flake8)

...

The jedi package is not available. Completion and code navigation will
not work.

[run] easy_install --user jedi

...

我已经安装了绝地，绳索，.，有以下命令

pip install jedi, rope

通过单击"run"，我得到以下消息：

Traceback (most recent call last):
  File "/usr/bin/easy_install-2.7", line 7, in <module>
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resources

我尝试了这个问题中所做的事情：资源来源。我更新我当前版本的pip，setuptools，分发，.但什么都不管用。我是否应该删除所有内容并重新启动(如果不删除所有内容，可能会很危险)？

我真的不知道从哪里开始。重新安装setuptool包没有更改任何内容。

以前，我安装了Python3.x，可能它破坏了安装。

任何帮助都是非常感谢的。

非常感谢。

现行建议将在你的虚拟环境中安装绝地/绳索。对于其他需求，您可能可以修改$PATH环境变量。
