Cannot find colorscheme error when setting colorscheme in plugin config

[AzurIce]

I'm trying to install and configure material.nvim

my lua/plugin/material.lua is as follows:

require('material').setup({
  -- ...
})

vim.cmd.colorscheme 'material'

error:

5113: Error while calling lua chunk: ...cal/share/nvim/rocks/rocks_rtp/lua/rocks-config/init.lua:41: /Users/azurice/.config
/nvim/lua/plugins/material.lua:69: Vim:E185: cannot find colorscheme 'material'
stack traceback:
        [C]: in function 'error'
        ...cal/share/nvim/rocks/rocks_rtp/lua/rocks-config/init.lua:41: in function 'setup'

        .../luarocks/rocks-5.1/rocks.nvim/2.19.1-1/plugin/rocks.lua:31: in main chunk

And it doesn't appear in the auto completion of :colorscheme,
But if I remove the line vim.cmd.colorscheme 'material', It shows in the colorscheme list, and I can use :colorscheme to set it correctly.

What's the proper way to set colorscheme?

Hey 👋

See this response regarding colorschemes 😃

I think we probably need to add some clearer documentation for colorschemes to the readmes. This is the third time this issue has come up 😅

Oh, I see! Thanks very much for your reply, and sorry for bothering again. 🤣

This is a rocks.nvim issue, so I've created nvim-neorocks/rocks.nvim#237.
Closing this as duplicate.
