Doesn't install in Comfyui 0.4.0

I've tried with Nodes 2.0 enabled and disabled. Installing rgthree-comfy via the Extension Manager reports to have worked but when it's through restarting the back end, it still shows as not installed.

Check your log when ComfyUI is starting, or paste the log here. There must be some python package conflict.
