下载安装

准备字体文件

下载：Nerd Fonts - Iconic font aggregator, glyphs/icons collection, & fonts patcher

选择字体：Agave Nerd Font

下载下来后，在windows系统上安装，然后xshell上设置一下：

image-20220425171043801

复制该链接上的Icon:https://www.nerdfonts.com/cheat-sheet

image-20220425171122978

粘贴到终端上，没问题的话，就会显示图标了：

image-20220425171212058

xhsell我还额外应用了主题，可能回合neo-vim的主题色冲突，建议使用默认的即可

centos环境

参考：Installing Neovim · neovim/neovim Wiki (github.com)

这里选择AppImage格式进行安装，操作以root用户，在/root目录下进行的

AppImage (“universal” Linux package)

The Releases page provides an AppImage that runs on most Linux systems. No installation is needed, just download nvim.appimage and run it. (It might not work if your Linux distribution is more than 4 years old.)

1
2
3
curl -LO https://github.com/neovim/neovim/releases/latest/download/nvim.appimage
chmod u+x nvim.appimage
./nvim.appimage

If the ./nvim.appimage command fails, try:

7
./nvim.appimage --appimage-extract
./squashfs-root/AppRun --version

# Optional: exposing nvim globally.
mv squashfs-root /
ln -s /squashfs-root/AppRun /usr/bin/nvim
nvim

chmod u+x nvim.appimage执行之后，我们挪一下位置，并且配置环境变量

5
mkdir /usr/bin/nvim
mv nvim.appimage /usr/bin/nvim/

cd /usr/bin/nvim/
ln -s /usr/bin/nvim/nvim.appimage nvim

编辑/etc/profile

1
export PATH=$PATH:/usr/bin/nvim

重新加载下配置文件：soruce /etc/profile

此时可以直接执行nvim，效果如下：

image-20220423081844276

输出nvim版本：nvim --version

替换默认的 vim （也可以不加）

nvim ~/.bashrc，添加别名：

1
2
3
alias vim='nvim'
alias vi='nvim'
alias v='nvim'

配置文件

nvim配置文件入口：~/.config/nvim/init.lua，如果没有可以新建

init.lua

1
require('basic')

新建~/.config/nvim/lua/basic.lua

vim lua/basic.lua

更新插件

如果出现如下报错，是因为git clone时，github连不上：

尝试更改plugin.lua的测试代码

return require('packer').startup(function()
  use 'wbthomason/packer.nvim'
end)

尝试手动安装插件：

1

cd ~/.local/share/nvim/site/pack/packer/start
git clone --depth 1 https://github.com/folke/tokyonight.nvim.git

检查packer.nvim

if fn.empty(fn.glob(install_path)) > 0 then
  packer_bootstrap = fn.system({'git', 'clone', '--depth', '1', 'https://github.com/wbthomason/packer.nvim', install_path})
end

return require('packer').startup(function(use)
  -- My plugins here
  -- use 'foo1/bar1.nvim'
  -- use 'foo2/bar2.nvim'

  -- Automatically set up your configuration after cloning packer.nvim
  -- Put this at the end after all plugins
  if packer_bootstrap then
    require('packer').sync()
  end
end)

      install        = 'clone --depth %i --no-single-branch --progress',

      get_msg        = 'log --color=never --pretty=format:FMT --no-show-signature HEAD -n 1',
      submodules     = 'submodule update --init --recursive --progress'
    },
    depth = 1, -- Git clone depth
    clone_timeout = 60, -- Timeout, in seconds, for git clones
    default_url_format = 'https://github.com/%s' -- Lua format string used for "aaa/bbb" style plugins
  },
}

记得最后在init.lua引入lua/colorscheme.lua！！

安装的话，即使是手动安装，也可以用
