Worker process failed [pid:undefined]

mediasoup-demo

Hi guys,

I was able to run this in one of my Mac successfully but failing in another, below is the error I receive when trying npm start after npm install. I have generated HTTPS localhost certificate and key and changed the config.js to reflect but as I can tell the problem is not there since there no chance to start the HTTPS server anyway.

Did npm install terminate successfully on that second Mac?

So mediasoup was not compiled in the failing machine so npm install did not success.

  • Enter mediasoup-demo/server/node_mocules/mediasoup and run npm install and paste the output.
  • BTW: do you have XCode installed in the failing machine and it runs Catalina? If so, ensure you run npm install again in mediasoup-demo/server since the latest mediasoup version is ready to compile in Catalina without XCode. Previous versions were not.

I thought it is related to XCode, in the beginning, I didn’t, then installed because the first error I received it was related to that, installed XCode, restarted mac, and run npm install but I assume yes, still something is missing.

It looks like it is finished successfully but with some audit issues.

EDIT: Both mac versions: 10.15.5 macOS Catalina

Audit issues are related to other deps of deps of deps in the mediasoup-demo project. Irrelevant here.

  • Please clone the mediasoup-demo again in a fresh folder, enter server/ directory and run npm install and paste the output.
  • After that, enter server/node_modules/mediasoup/worker, run make and paste the output.
  • In addition, confirm whether you have /usr/sbin/softwareupdate command or not in your system.

confirmed command exist: /usr/sbin/softwareupdate

It just worked fine. What’s the problem now? There shouldn’t be any problem if you run the demo server now in that new installation.

I was just about to respond :slight_smile:

This time it worked fine! Thank you guys :slight_smile:

Probably you installed now the latest mediasoup v3 branch which can compile without XCode. Such a commit was just pushed today.

10

That makes sense since we were trying yesterday before installing Xcode and npm installed failed. Nicely done, time to learn the APIs and start sending video/audio!

I am getting same error after deploy by using docker.

12

Did you read the mediasoup installation requirements?

13

Sorry, this issue was related with Docker setting.
Thanks

14

How did you resolve the issue?

15

I solved my issue by adding dependencies to the Node image.
Here is a final Dockerfile

See the step with deb dependencies

FROM node:12

# Install DEB dependencies
RUN \
    set -x \
    && apt-get update \
    && apt-get install -y net-tools build-essential valgrind


WORKDIR /usr/src/app

COPY package*.json ./

RUN npm install

COPY . ./

RUN npm run build

CMD [ "npm", "run", "start:prod" ]
