关于golang:从0开始在centos安装neovimgo开发环境

在本人的环境变量中配置好 go 的 path

 77 export GOROOT=/usr/local/go
 78 export PATH=$PATH:$GOROOT/bin
 79 export GOPATH=/data/gowork

1. 在官网下载 nvim-linux64.tar.gz 这个安装包
tar -zxvf nvim-linux64.tar.gz 解压后应用 ln - s 建设链接

ln -s /root/nvim/nvim-linux64/bin/nvim nvim

#在配置文件中增加申明，使 nvim 成为关键字
export PATH=$PATH:/root/nvim/nvim-linux64/bin

而后就能够像应用 vim 一样应用 nvim 了

因为后续装置的一些代码补全插件须要这两个组件的反对，所以先提前装置

1. 先去 https://npm.taobao.org/mirror…
2.tar zxvf 解压到想要寄存的文件目录下
3. 在 /etc/profile 文件中申明

export PATH=$PATH:/root/node/node-v14.16.1-linux-x64/bin

4. 设立链接

ln -s  /root/node/node-v14.16.1-linux-x64/bin/npm ~/npm
ln -s  /root/node/node-v14.16.1-linux-x64/bin/node ~/node
#source 让配置的 path 失效
source /etc/profile

[root@VM-0-16-centos ~]# npm -v
6.14.12
[root@VM-0-16-centos ~]# node -v
v14.16.1


查看版本胜利即装置胜利

1. 下载 python 安装包
https://www.python.org/ftp/py…

2.tar -xzf Python-3.8.6rc1.tgz
3. 进入解压完的目录执行如下命令，门路为想装置的 py 门路
./configure –prefix=”/root/python3.8″
4. 等执行完后持续在解压完的目录下顺次执行
make
make install
5. 编译实现后在环境变量中增加

alias python3=/root/python3.8/bin/python3.8
alias pip3=/root/python3.8/bin/pip3.8

而后查看
pthone3 -v
pip3 -v
测验装置胜利

1. 创立 mkdir -p ~/./config/nvim 文件夹
而后在~/./config/nvim 中创立

init.vim 文件（相当于配置文件）
pulgged 文件夹（在配置文件中设置插件下载保留的地位）
autoload 文件夹（放 plug.vim）

2.git clone https://github.com/junegunn/v…
进入 vim-plug 目录将 plug.vim 这个文件拷贝到刚刚创立的 autoload 文件夹中

3.nvim 关上 init.vim
输出

" 插件开始的地位
call plug#begin('~/.vim/plugged')

Plug 'fatih/vim-go', {'tag': '*'}
Plug 'neoclide/coc.nvim',{'branch':'release'}
Plug 'Valloric/YouCompleteMe'
" 插件完结的地位，插件全副放在此行下面
call plug#end()

这三个是 go 的次要插件

这个是 vim-go 相干的配置，也是写在 init.vim 里就行了。（不要和插件内容写混了）

" vim-go
let g:go_fmt_command = 'goimports'
let g:go_autodetect_gopath = 1
"let g:go_bin_path ='$GOBIN'

let g:go_highlight_types = 1
let g:go_highlight_fields = 1
let g:go_highlight_functions = 1
let g:go_highlight_function_calls = 1
let g:go_highlight_extra_types = 1
let g:go_highlight_generate_tags = 1

" Open :GoDeclsDir with ctrl-g
nmap <C-g> :GoDeclsDir<cr>
imap <C-g> <esc>:<C-u>GoDeclsDir<cr>

augroup go
  autocmd!
  autocmd BufNewFile,BufRead *.go setlocal noexpandtab tabstop=4 shiftwidth=4
augroup END

4. 而后关上一个 nvim 窗口，在命令模式下输出 PlugInstall 装置插件

5. 装置结束后再在命令模式下输出 GoInstallBinaries 装置 vim-go 所须要的一些插件
这个默认是装置在 gobin 目录下的，如果下载失败输出
export GOPROXY=https://goproxy.io,direct
再重试下

6. 再关上 nvim 在命令模式下输出 CocInstall coc-go coc-json coc-snippets coc-yaml
装置 coc 相干的插件
