VIM搭建PYTHON开发环境

参考

Vim与Python真乃天作之合：打造强大的Python开发环境

系统

CentOS 7.3

问题记录

PEP8
添加'|'符号

au BufNewFile,BufRead *.py
set tabstop=4 |
set softtabstop=4 |
set shiftwidth=4 |
set textwidth=79 |
set expandtab |
set autoindent |
set fileformat=unix

标示不必要的空白字符
添加

highlight BadWhitespace ctermbg=red guibg=darkred

退格键backspace不能退到前一行尾

set backspace=indent,eol,start

安装YouCompleteMe
执行vim提示

YouCompleteMe unavailable: requires Vim 7.4.1578+.

因为vim版本是7.4.160所以怀疑是不是安装ycm有问题，决定自己重新编译vim一下试试(结果不行，最后还是升级到vim8.0)
使用补全功能提示

YCM core library not...need to compile YCM before using it,

需重新编译YCM
进入YCM文件夹,执行 ./install.py
报错如下：

-- NOTE: You appear to be on CentOS version 7.3.1611. In order to use this application, you require a more modern compiler than the default compiler on this platform. Please install the devtoolset-6 or greater. For example, see this link: https://www.softwarecollections.org/en/scls/rhscl/devtoolset-6/

解决方案

1. Install a package with repository for your system:
   On CentOS, install package centos-release-scl available in CentOS repository:
   $ sudo yum install centos-release-scl
   On RHEL, enable RHSCL repository for you system:
   $ sudo yum-config-manager --enable rhel-server-rhscl-7-rpms
2. Install the collection:
   $ sudo yum install devtoolset-6
3. Start using software collections:
   $ scl enable devtoolset-6 bash
   注意：要在同一个用户下执行3个命令
   执行 ./install.py
   报错如下：

   解决方案
   sudo ./install.py 成功
   但是依然报错

   YouCompleteMe unavailable: requires Vim 7.4.1578+.
   

   升级vim到8.0，成功解决,参考
