nerdtree 自动切换到当前目录

set autochdir
let NERDTreeChDirMode=2
nnoremap <leader>n :NERDTree .<CR>

so that NERDTree always opens in the current folder.

• With the 1st line, the working directory is always the one where the active buffer is located.
• With the 2nd line, I make sure the working directory is set correctly.
• With the 3rd line, I hit <leader>n to open NERDTree.
