I am going to let it this run to see if it will complete, but as of now it has been 10 minutes.

Is there another library that should be installed to speed this up?

Thanks

You'll generally get a faster install with a wheel -- make sure you have the latest pip and setuptools installed.

Otherwise we need to build libsodium, which can take some time.

Stuck at same place, the server is freezing, never got issues when I compiling other packages(include chromium).

EDIT: it take all 128G memory and 4G swap

EDIT1: I solve it by install pynacl 1.1.2. Before the server freezing, I found the program pwhash_scrypt take most memory, which is from libsodium. Then I google it, found some similar issues here: jedisct1/libsodium#721 , then I found this commit charmed-kubernetes/jenkins#360 , which install pynacl 1.1.2 instead of latest version. So I modified pynacl version in /opt/stack/requirements/upper-constraints.txt (I'm trying to install openstack with devstack on an aarch64 server), and this fix the issues.

FYI:
jedisct1/libsodium#890

In short, in my case, mmap would try to map an enormous amount of memory and eventually fail. I also had vm.memory_overcommit set to 1, setting it to 0 or 2 should fix the problem.

It would be really nice if PyNaCl moved to an earlier version of libsodium, as 1.0.16 is at least an year old.
