vim mapleader 无法正常工作

vim mapleader 无法正常工作

我在 vim 中设置了 mapleader，如下所示

let mapleader = ","

当我尝试

:echo mapleader

它显示,正确

但以下不起作用

nnoremap <leader>a :echo("\<leader\> works! It is set to <leader>")<CR>

由于无法正确设置领导者，因此我无法使用 vimwiki。

经过大量的 Google 搜索后，我感到很沮丧。请帮忙。

我还安装了 gvim 来使用 vimwiki。设置的所有多个 wiki 都可以通过 gvim 访问，但不能通过 vim 访问。

以下是我的 vimrc 文件

答案1

在 .vimrc 中添加以下行解决了我的问题

let g:mapleader = ","

答案2

我发现我得到了输出

<leader> works! It is set to ','

设置后

:let mapleader = ","
:nnoremap <leader>a :echo("\<leader\> works! It is set to '<leader>'")<CR>

我之前遇到了与引号相关的错误。

就我个人而言，我发现使用

map , <Leader>

,a在测试时vim一定要:source vimrc查看所实施的更改vimrc。
