关于golang:从0开始在centos安装neovimgo开发环境

一、配置GO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

二、装置nvim

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

三、装置nodejs & pythone3

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.装置nodejs

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 ~/npmln -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 -v6.14.12[root@VM-0-16-centos ~]# node -vv14.16.1查看版本胜利即装置胜利

2.装置python3

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

而后查看
pthone3 -v
pip3 -v
测验装置胜利

四、装置nvim的插件

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-golet g:go_fmt_command = 'goimports'let g:go_autodetect_gopath = 1" let g:go_bin_path = '$GOBIN'let g:go_highlight_types = 1let g:go_highlight_fields = 1let g:go_highlight_functions = 1let g:go_highlight_function_calls = 1let g:go_highlight_extra_types = 1let g:go_highlight_generate_tags = 1" Open :GoDeclsDir with ctrl-gnmap <C-g> :GoDeclsDir<cr>imap <C-g> <esc>:<C-u>GoDeclsDir<cr>augroup go  autocmd!  autocmd BufNewFile,BufRead *.go setlocal noexpandtab tabstop=4 shiftwidth=4augroup 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

最初是一些init.vim的配置
