vim编辑器配置
都说vim编辑器十分强大，最近根据网上博主的文章配置了一下，现将配置过程中的注意事项记录一下。
vim配置主要有两个部分：配置vim配置文件、管理vim插件
1.vim配置文件需要自己在~/目录下新建一个名为.vimrc的文件(touch .vimrc)，之后在其中写入vim的基本配置和插件配置，在配置文件中，可以使用双引号标记注释，如：
1 ”这是一行注释
2.vim插件放置在~/.vim/bundle/目录下，主要使用插件管理器Vundle管理。
vim插件安装时，需要在配置文件中写入插件配置，然后打开vim编辑器输入 :PluginInstall，之后vim会自动下载并安装插件。
vim自动下载插件时会从github上下载插件，但下载速度非常慢而且容易出错，所以可以在github找到相关插件后，复制地址，然后挂载到码云(https://gitee.com/)上，或者直接在码云上搜索相关插件(很多人已经挂载过来了)，然后点击fork挂载到自己的仓库下，然后复制地址，在~/.vim/bundle/目录下执行指令：git clone 插件地址 ，就可以将插件下载下来了。之后打开vim，输入:PluginInstall ，就可以安装了，安装成功后会在vim下方显示：Done.
3.参考博客https://blog.csdn.net/zziahgf/article/details/49757185
https://blog.csdn.net/dreamdgl/article/details/79433975
4.问题解决
设置代码缩进
au BufNewFile,BufRead *.py \ set tabstop=4| \ set softtabstop=4| \ set shiftwidth=4| \ set textwidth=79| \ set expandtab| \ set autoindent| \ set fileformat=unix au BufNewFile,BufRead *.js, *.html, *.css \ set tabstop=2| \ set softtabstop=2| \ set shiftwidth=2|
支持Virtualenv虚拟环境
开始时，将第二行py3 << EOF写为py << EOF，打开vim，报错，改为py3后正常
"python with virtualenv support--------------------------------------------- py3 << EOF import os import sys if 'VIRTUAL_ENV' in os.environ: project_base_dir = os.environ['VIRTUAL_ENV'] activate_this = os.path.join(project_base_dir, 'bin/activate_this.py') execfile(activate_this, dict(__file__=activate_this)) EOF
添加配色方案
下载安装完插件，报错，Cannot find color scheme 'solarized'，根据网上办法，先在~/.vim/目录下新建目录：mkdir colors，之后执行如下命令
cp ~/.vim/bundle/vim-colors-solarized/colors/solarized.vim ~/.vim/colors/
发现提示找不到Zenburn，遂将配置文件中的colorscheme Zenburn改为colorscheme zenburn，正常
Plugin 'jnurmine/Zenburn' Plugin 'altercation/vim-colors-solarized' if has('gui_running') set background=dark colorscheme solarized else colorscheme zenburn endif call togglebg#map("<F5>")
5. GVIM，vim的界面版，安装后可以使用vim的所有配置，可以作为vim鼠标到键盘的过渡版本。gvim可以通过其界面上的菜单选项进行各种设置。

补充：
ctags安装：sudo apt install ctags
nodejs环境：ubuntu16.04/18.04配置nodejs环境，安装npm (需要安装16版本的nodejs，用以下指令替换原博客中的安装nodejs 10的指令
curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -
sudo apt-get install -y nodejs
卸载原有yarn:
sudo apt remove cmdtest
安装yarn:
sudo npm install -g yarn
)
coc.nvim编译[参考：https://blog.csdn.net/qq_34548075/article/details/120092169]：
cd ~/.vim/plugged/coc.nvim/
yarn install
yarn build
