paste the missing nodes in here https://comfy.icu/node, it'll link to github repos which you cd into ComfyUI\custom_nodes then git clone the repo (the url ending in .git from the green "code" dropdown menu) like "git clone https://github.com/PowerShell/PowerShell.git" then cd into the new directory (in this case would be ComfyUI\custom_nodes\PowerShell, which is totally random but works for my explanation) and in there do dir (in windows) or ls (in linux/mac) and if there's a requirements.txt file do "pip install -r requirements.txt" (be sure you've activated the virtual environment if you're using one) and if there's not a req txt file it'll sort itself out when you close and restart the comfyui server. If this is a rambling bunch of nonsense you can DM me on Session and I'll help you get it sorted out, my ID is 05ff41120be1970c63d7936518380951bda6116bc37db4892a8a0417899fdde22c
