Bug Description

I am unable to install community nodes using UI.

To Reproduce

  1. Go to Settings > Install Community Node
  2. Type the name n8n-nodes-evolution-api
  3. Notice that the installation fails with error: 500 Error loading package "n8n-nodes-evolution-api" :Failed to execute npm command Cause: spawn npm ENOENT
  4. Alternatively, manually install the node in .n8n, yet the node is not visible in the community nodes section.

This is all without the docker image.

Expected behavior

Installation should succeed and the node should be visible in the community nodes section.
