從0開始在centos安裝neovim-go開發環境

1、配置GO環境

在本身的環境變量中配置好go的path

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

2、安裝nvim

1.在官網下載 nvim-linux64.tar.gz 這個安裝包
tar -zxvf nvim-linux64.tar.gz 解壓後使用 ln -s創建連接

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

#在配置文件中添加聲明，使nvim成爲關鍵字
export PATH=$PATH:/root/nvim/nvim-linux64/bin

而後就能夠像使用vim同樣使用nvim了

3、安裝nodejs & pythone3

由於後續安裝的一些代碼補全插件須要這兩個組件的支持，因此先提早安裝

1.安裝nodejs

1.先去https://npm.taobao.org/mirror...
2.tar zxvf 解壓到想要存放的文件目錄下
3.在/etc/profile 文件中聲明

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

4.設立連接

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 讓配置的path生效
source /etc/profile

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


檢查版本成功即安裝成功

2.安裝python3

1.下載python安裝包
https://www.python.org/ftp/py...

2.tar -xzf Python-3.8.6rc1.tgz
3.進入解壓完的目錄 執行以下命令， 路徑爲想安裝的py路徑
./configure --prefix="/root/python3.8"
4.等執行完後繼續在解壓完的目錄下依次執行
make
make install
5.編譯完成後在環境變量中添加

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

而後查看
pthone3 -v
pip3 -v
檢驗安裝成功

4、安裝nvim的插件

1.建立 mkdir -p ~/./config/nvim 文件夾
而後在~/./config/nvim中建立

1. init.vim 文件 （至關於配置文件）
2. pulgged 文件夾 （在配置文件中設置插件下載保存的位置）
3. autoload 文件夾 （放plug.vim）

2.git clone https://github.com/junegunn/v...
進入vim-plug目錄將 plug.vim這個文件拷貝到剛剛建立的autoload文件夾中

3.nvim 打開init.vim
輸入

" 插件開始的位置
call plug#begin('~/.vim/plugged')

Plug 'fatih/vim-go', { 'tag': '*' }
Plug 'neoclide/coc.nvim',{'branch':'release'}
Plug 'Valloric/YouCompleteMe'
" 插件結束的位置，插件所有放在此行上面
call plug#end()

這三個是go的主要插件

這個是vim-go相關的配置，也是寫在init.vim裏就好了。（不要和插件內容寫混了）

" 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.而後打開一個nvim窗口，在命令模式下輸入 PlugInstall 安裝插件

5.安裝完畢後再在命令模式下輸入 GoInstallBinaries 安裝vim-go所須要的一些插件
這個默認是安裝在gobin目錄下的，若是下載失敗輸入
export GOPROXY=https://goproxy.io,direct
再重試下

6.再打開nvim 在命令模式下輸入 CocInstall coc-go coc-json coc-snippets coc-yaml
安裝coc相關的插件
