Hi,

hi Hrishikesh,

I am building CEPH for RiscV on Debian.
I am getting the following error. Can you guide me on how to resolve this?

we are using nodeenv[0] for preparing the nodejs environment. the
error you ran into is related to
https://github.com/ekalinin/nodeenv/blob/master/nodeenv.py#L533. but a
bigger problem is that nodeenv tries to pull precompiled nodejs from
https://nodejs.org/download/release/ where nodejs.org keeps binaries
of different nodejs versions precompiled for different architectures.
for instance, https://nodejs.org/download/release/latest-v10.x/ is
where the v10.x binaries are hosted. but RISC-V is missing there. so
you probably either need to help them to build for RISC-V or find an
alternative mirror hosting precompiled RISC-V.

HTH,

You can also patch it to use `nodeenv --node=system` if nodejs is available in the Debian repos for riscv64

A bit like this patch for octopus: https://git.alpinelinux.org/aports/tree/community/ceph/42-no-virtualenvs.patch?h=3.13-stable
