Failed to load resource:/nova-vendor/guratr/command-runner/commands/:1

when I install the package (https://github.com/guratr/nova-command-runner) it doesn't load me the commands even if I remove the comments.

and I have the following situation:

I noticed that the browser reports me the following errors:

Failed to load resource: the server responded with a status of 404 (Not Found): 404 : /nova-vendor/guratr/command-runner/commands/:1 Failed to load resource: the server responded with a status of 404 (Not Found): /nova-vendor/guratr/command-runner/history/:1 Uncaught (in promise) Error: Request failed with status code 404 : vendor.js?id=3810bf2033e3670b2acc:1

how can i solve?
