从0开始在centos安装neovim-go开发环境

Posted 2021-09-12 悦动的普朗克

一、配置GO环境

在自己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、安装nvim

1.在官网下载 nvim-linux64.tar.gz 这个安装包
tar -zxvf nvim-linux64.tar.gz 解压后使用 ln -s建立链接

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

#在配置文件中添加声明，使nvim成为关键字
export PATH=$PATH:/root/nvim/nvim-linux64/bin

然后就可以像使用vim一样使用nvim了

三、安装nodejs & pythone3

因为后续安装的一些代码补全插件需要这两个组件的支持，所以先提前安装

1.安装nodejs

1.先去https://npm.taobao.org/mirror...
2.tar zxvf 解压到想要存放的文件目录下
3.在/etc/profile 文件中声明

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


检查版本成功即安装成功

2.安装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， 路径为想安装的py路径
./configure --prefix="/root/python3.8"
4.等执行完后继续在解压完的目录下依次执行
make
make install
5.编译完成后在环境变量中添加

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

然后查看
pthone3 -v
pip3 -v
检验安装成功

四、安装nvim的插件

1.创建 mkdir -p ~/./config/nvim 文件夹
然后在~/./config/nvim中创建

1. init.vim 文件 （相当于配置文件）
2. pulgged 文件夹 （在配置文件中设置插件下载保存的位置）
3. 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建的autoload文件夹中

3.nvim 打开init.vim
输入

" 插件开始的位置
call plug#begin(\'~/.vim/plugged\')

Plug \'fatih/vim-go\', { \'tag\': \'*\' }
Plug \'neoclide/coc.nvim\',{\'branch\':\'release\'}
Plug \'Valloric/YouCompleteMe\'
" 插件结束的位置，插件全部放在此行上面
call plug#end()

这三个是go的主要插件

这个是vim-go相关的配置，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.然后打开一个nvim窗口，在命令模式下输入 PlugInstall 安装插件

5.安装完毕后再在命令模式下输入 GoInstallBinaries 安装vim-go所需要的一些插件
这个默认是安装在gobin目录下的，如果下载失败输入
export GOPROXY=https://goproxy.io,direct
再重试下

6.再打开nvim 在命令模式下输入 CocInstall coc-go coc-json coc-snippets coc-yaml
安装coc相关的插件

最后是一些init.vim的配置
