Vuepress hangs during build in isolated environment

[MatthiasvB]

• [x ] I confirm that this is an issue rather than a question.

Bug report

Steps to reproduce

What is expected?

With all dependencies installed, vuepress should build even in isolated environments

What is actually happening?

The build hangs indefinetly in the stage "Initializing and preparing data".

Other relevant information

The isolated environment I'm talking about is the nix build environment. You can very easily reproduce this if you have nix installed (and nix-command and flakes enabled via extra-experimental-features), cloned the MWE, enter the project dir and run nix build. In contrast, when you just run nix develop to enter a dev shell and then run npm run docs:build it works fine.

Interestingly, even disabling the sandbox does not help (nix build --no-sandbox). I am not sure, but the most "unusual" thing is that this probably still runs in a chroot.

Nix is a generic package manager focused on reproducibility, which is why all builds happen in an isolated environment where all env vars are unset and access to the network is cut.

You can install Nix on Unix with sh <(curl -L https://nixos.org/nix/install) --daemon source. To enable said experimental features, run sudo bash -c 'echo "extra-experimental-features = nix-command flakes" >> /etc/nix/nix.conf' (at least on Linux).
