file not found error in solidity files when importing from node_modules

[pchabros]

Hi Christian,

Sorry if this is not the best way to ask the question, but
can you please, please help me with those annoying errors? :)

I've copied from your config files:

require("lspconfig").solang.setup({
  cmd = { "solang", "--language-server", "--target", "ewasm", "--importpath", "node_modules/" },
})
require("lspconfig").solc.setup({
  cmd = { "solc", "--lsp", "--include-path", "../node_modules" },
})

but I still have those errors :/

yea, this was only me testing to see if I could make that work, but I wasn't able to make it work. Doesn't work in VSCode either btw. I would recommend reaching out on the solang and the official solc LSP repos and see if they can help.

Also let me know if you ever solve this.

• For solc, the --lsp mode doesnt support --include-path yet, as per 12994.
• For now, i have been using solidity ls with these settings:

return {
    root_dir = function (fname)
        local git_root = require("lspconfig").util.find_git_ancestor(fname)
        local pkg_root = require("lspconfig").util.find_package_json_ancestor(fname)

        if git_root then
            return git_root
        elseif pkg_root then
            return pkg_root
        end
    end,
	settings = {
		solidity = {
			packageDefaultDependenciesContractDirectory = "",
			packageDefaultDependenciesDirectory = "node_modules",
			enabledAsYouTypeCompilationErrorCheck = true,
			linter = "solhint",
		},
	},
}

• I cant seem to get the autocomplete feature for openzeppelin contracts to work, but i can gotoDefinition
• With solidity ls, it populates cmp with the imported contract's functions though (eg: when importing ERC721, cmp will have completion for methods like _safeMint etc)

[edit]

• I got the openzeppelin auto completion import working by creating a binding in cmp to open the cmp menu

["<C-y>"] = cmp.mapping({
    i = cmp.mapping.complete(),
}),
