在过去的两周里，我没有使用 emacs 进行 python 编码，到那时一切都很完美，我的设置运行良好，包括绝地。
两天前我安装virtualenvwrapper在 python ( pip install virtualenvwrapper) 中，这就是我的 python 安装中从两周到今天发生的所有变化。我的 emacs 安装/设置没有任何变化，绝对没有。今天，两周内我第一次开始用 python 编码，当我emacs test.py在终端中输入时，我在emacs窗口中收到以下错误消息：
Error (jedi): Failed to start Jedi EPC server.
*** You may need to run "M-x jedi:install-server". ***
This could solve the problem especially if you haven't run the command yet
since Jedi.el installation or update and if the server complains about
Python module imports.

这是我jedi一年前安装的方式：
1-我首先按照这里的说明进行绝地安装。顺便说一句，epc, argparse, jedi并且virtualenv已经安装在 python 中，当然。
2-我在某处（我不记得在哪里）读到 melpa 的 jedi 包没有更新。这对我来说听起来很奇怪，但我决定直接从 github 下载：jedi-githubjedi和python-environment-github。我把它们放在和python-environment~/.emacs.d/emacs-jedi/~/.emacs.d/emacs-python-environment/
3-然后通过执行以下操作进行设置jedi：
;;Standard Jedi.el setting (read readme-jedi at .emacs.d/)
(add-to-list 'load-path "~/.emacs.d/emacs-jedi/")
(add-to-list 'load-path "~/.emacs.d/emacs-python-environment/")
(add-hook 'python-mode-hook 'jedi:setup)
(setq jedi:complete-on-dot t)
4-我在emacs上运行：M-x jedi:install-server
完成了！直到今天，这对我来说已经工作了一年！
当然，作为解决此问题的第一次尝试，我完全按照错误消息的建议执行并运行（再次）M-x jedi:install-server。然后我得到以下错误：

在此之后，以及其他一些尝试，我决定重新安装所有东西，只使用 melpa。（即在绝地安装之后）。然后我运行M-x jedi:install-server并收到与之前描述的非常相似的错误消息：

总而言之，在这个阶段，我的文件或我的目录与原始安装相比没有任何变化。.emacs.emacs.d
在过去两天里对我的 python 包安装所做的所有更改都是简单的virtualenvwrapper. 在这个阶段我很迷茫。非常感谢任何帮助。
在此先感谢您的时间。
