I want a one step setup or a line of bash

@butterfly1924 what os you on?

If you dont mind terminal programs and vim keybindings for everything you can use my mern stack version of larbs: https://github.com/AshMagill/mernrod

nerdtree always opens twice when pressing ctrl + n
and i don't know why

I want the current line number to be displayed instead of "0" wherever the cursor is. What do I edit in my init.vim file? I want the relative lines up and down, but the current line must show the current line number

Have you done yet? Just type in set relativenumber number same line in the init.vim file

nerdtree always opens twice when pressing ^n and i don't know why

@shihongji

I had this same issue. After checking for how to fix it, I found this SO answer: https://vi.stackexchange.com/questions/22881/nerdtreetoggle-always-opens-up-two-directory-windows-instead-of-one#:~:text=autocmd%20BufRead%20*%20call%20SyncTree()

Changing BufWrite to BufRead like that answer suggests worked for me.

There is a new problem for coc.nvim in 0.0.82 saying:

" coc.nvim has switched to custom popup menu from 0.0.82 you have to change key-mappings for , to make them work. see :h coc-completion-example "

[coc.nvim] "node" is not executable, checkout https://nodejs.org/en/download/

I believe you need to have node installed on your computer, because if you copied the config files then coc automatically installs tsserver (which requires node), however if you don't want to install it then you can just remove 'coc-tsserver' from the config file.

1. Plug.vim content

whenever i click on the download link it doesn't initiate a down. rather it takes me to the file itself on my browser

1. ~/.local/share/nvim/site/autoload/plug.vim

i keep getting that directory doesn't exist when i try to copy the plug.vim file to the autoload folder
any help?

I get following errors

line   59:
E492: Not an editor command: PrettierAsync
line  110:
E690: Missing "in" after :for
line  229:
E170: Missing :endfor
Press ENTER or type command to continue```
