NameError: name 'WindowsError' is not defined

[tweak-wtf]

I run bleeding-rez 2.40.4 in a dedicated conda environment on ubuntu. I'm trying to bind packages to a custom packages directory that is on a network share. When running rez-bind --quickstart -i /mnt/<PATH_TO_SHARE> i get:

NameError: name 'WindowsError' is not defined

I want to build and deploy packages on ubuntu since building is kinda quirky on windows but users resolving rezenvs are on windows.

That's interesting. Does it give you a file and line number? Try replacing any reference to WindowsError with OSError.

yeah it's the serialise.py in the rez installation on line 74. When replacing with with OSError i get the following stacktrace.

I added some debugging prints for myself. It seems that it has problem writing package.py but the contents the AtomicWriter wants to write are present on disk.

Edit: update log output, better explanation

Hm, looks like an issue with the network mount and that atomic package. Is this mounted in a Docker container? Give this a try in vanilla-rez and see if the same occurs. The packages it builds for you work with either one.

[tweak-wtf]

No this is a simple synology share... I figured it out by replacing the drive letter with the DNS name of the server. This works just fine, so you may close this issue :)

Cool, thanks for the update. 👍
