Cannot install webrtc branch

[asmaps]

I'm trying to set up the webrtc version but the building always fails. npm run build quits with this error:

ERROR in ./node_modules/mumble-client/index.js
Module not found: Error: Can't resolve './lib/client.js' in '/opt/mumble-web/node_modules/mumble-client'
 @ ./node_modules/mumble-client/index.js 1:17-43
 @ ./app/index.js
 @ multi ./app/index.js ./app/index.html

ERROR in ./node_modules/mumble-client-websocket/index.js
Module not found: Error: Can't resolve './lib/index.js' in '/opt/mumble-web/node_modules/mumble-client-websocket'
 @ ./node_modules/mumble-client-websocket/index.js 1:17-42
 @ ./app/index.js
 @ multi ./app/index.js ./app/index.html

I don't know the packaging mechanisms in npm too well, but it seems like it clones the mumble-client repo but doesn't build it, hence the lib directory doesn't exist.

Am I doing something wrong or is this a bug?

Building with this Dockerfile:

FROM node:14.2-stretch

USER root
RUN apt-get update && apt-get install -y libnice-dev clang
ADD rustup.sh /opt
RUN /opt/rustup.sh -y
WORKDIR /opt
RUN git clone https://github.com/Johni0702/mumble-web-proxy && cd mumble-web-proxy && git checkout 2a95f11d304d20dca0741ebc9fbc5502fbbf4acb

WORKDIR /opt/mumble-web-proxy
RUN /root/.cargo/bin/cargo build --release

WORKDIR /opt
RUN git clone -b webrtc https://github.com/Johni0702/mumble-web && cd mumble-web && git checkout 456a2fcf8c019e6281e0ded41aaab4e5576e1222
WORKDIR /opt/mumble-web
RUN npm install
RUN npm run build
VOLUME ["/opt/mumble-web"]

USER 1000
CMD ["/opt/mumble-web-proxy/target/release/mumble-web-proxy", "--listen-ws", "64737", "--server", "mumble:64738"]

Also tried installing and building with yarn, but didn't change anything.

don't build as root.

Yup, npm behaves different when running as root. In particular it won't run any scripts (most of the time) hence why the mumble-client repo was only cloned but not built.
