10/19/2023, 10:41 AMThis is absolutely not a Pex thing - no space left on device - it's real and it means what it says. Now the Pex part is only that PEX files are zips and when you 1st run them, they self extract to disk 1st. So you must have less disk space than needed to self-extract the PEX zip to the PEX_ROOT dir. That directory defaults to ~/.pex but a tmp dir is used if that dir is not writable.

10/19/2023, 12:08 PMMy disk has 350gb free, so I am definitely not running out of storage. Not sure if Docker puts any limits on storage, I'll have to google that.

10/19/2023, 12:18 PMNo, I'm not running out of memory either, it must be something else.

10/19/2023, 12:20 PMAh ok, this seems like a Docker issue on my end, I am getting some other OOS messages now as well from the docker daemon. So nothing PEX related! Thank you for responding.

10/19/2023, 12:36 PMYes, OSX uses a Linux VM for running docker under the hood that uses a disk that you need to manage storage for. Just in case anyone runs into the same issue! My fault for being a noob about Docker on OSX.
