无法保存文件：“未找到autopep8命令”

Question

我正在用emacs运行python。我已经编写了一些代码，现在我将使用C-x C-s保存代码。但是，autopep8 command not found没有保存，而是出现在小型缓冲区中。我无法保存我的密码。

我能做什么来恢复功能到emacs和保存我的文件？

这是我的init.el

Answer 1

安装提供命令autopep8的包，或者删除行

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

从你的配置。安装可以使用pip或包管理器完成，这取决于您的系统。在Ubuntu上，这将是

sudo apt-get install python-autopep8

或

pip install autopep8
