meshcat-server command not working

[rickyduh]

Whenever I run meshcat-server, the page that opens up says error 404 not found and this is what is displayed in my command window: zmq_url=tcp://127.0.0.1:6000 web_url=http://127.0.0.1:7000/static/ Firefox hook launcher starting up run-parts: executing /usr/lib/amazon/firefox-hooks/00amazon-firefox-certs Notice: Trust flag u is set automatically if the private key is present.

any ideas on this?

[rickyduh]

I fixed the issue by running python meshcat-server instead of just meshcat server

The only thing I can think of is that perhaps Firefox is being opened before the server is actually ready. Does refreshing the page have any effect?

I'm facing a similar issue. Here is the output I get from running meshcat-server:

zmq_url=tcp://127.0.0.1:6000
web_url=http://127.0.0.1:7000/static/
WARNING:tornado.access:404 GET /static/ (127.0.0.1) 1.80ms

The last line shows up when I open the URL (http://127.0.0.1:7000/static/). Do you have any thoughts on what may be causing this tornado issue and the 404 error? I get the same issue when I run the demo notebooks.

I have the same problem as you. Have you solved it ？

I ran into the same problem when working on submitting a patch for meshcat-python: so I had cloned the meshcat-python repo and run pip install . inside.

The issue was that I had forgotten to checkout the submodules ! git submodule update --init --recursive solved the problem for me

I am facing such an error

RuntimeError: the meshcat server process exited prematurely with exit code 1

what should i do?

Looks like you can start it with python -m meshcat.servers.zmqserver.
