I am trying to run this command on CircleCI:
sudo npm install -g --loglevel=warn @oresoftware/r2g
I get this error:

This problem is not particular to CircleCI - this happens in Docker or wherever the wrong permissions are setup.
My question is - if I am the root user - where my $HOME is /root, why would I get a permissions error, when I run:
mkdir -p /root/.r2g/temp/project
As you can see, it failed at the very first dir - I cannot create /root. Even though it already exists, almost certainly, and I should be the root user, where /root is my $HOME dir.
Does anyone know if there is a fix for this on Linux systems? Is there some command I can run to get permissions to my own home directory as root?
I am trying to find a solution that is generic and not forceful.
I tried running this before the npm install command:
sudo chown -R $(whoami) $HOME
That didn't do anything, same error.
A simple 2-line Dockerfile will yield this same exact issue:
FROM node:10
RUN npm install -g @oresoftware/r2g
and it also fails with the same error for this 3-line Dockerfile:
FROM node:10
RUN apt-get update && apt-get install -y sudo
RUN sudo npm install -g @oresoftware/r2g
Here is the postinstall.sh script.
I have cross-posted this question to the CircleCI help forum.
It seems that npm install does a setuid and setgid to nobody. So basically before it runs the postinstall script it changes the user to nobody - a user which of course has no rights to write to /root.
To prevent this you can set the --unsafe-perm flag to true:
npm install --unsafe-perm=true -g @oresoftware/r2g
After that it worked with the docker-example.
