I do not get it. There was no issue with the last version of openstudio-standards.
I have got two related issues:

• Create doe prototype building measure does not work with OpenStudio Application 1.8.0 (Create doe prototype building "SWIG director method error. IOError: not opened for reading" in OpenStudioApplication 1.8.0 openstudio-model-articulation-gem#145), but it does work when embedding openstudio-standards 0.6.3 (openstudio-standards 0.6.1 is embedded in OpenStudio 3.8.0). In my opinion, the simplest fix is updating openstudio-standards in openstudio-gems: Update openstudio-standards to 0.6.3 openstudio-gems#96.
• I do not know how to make OS CLI consider environment variables when setting a gems path (How to use last release of openstudio-standards? #1815). If it needs a fix, that should happen in the OpenStudio repo and not here.

So, what does this PR fix?

I was able to recreate the issue in openstudio-standards 0.6.3, and it related to using Dir.pwd instead of __dir__ to get the relative location of the bundled weather files regardless of where the script was run from.

You can follow these instructions to use custom gem versions with OpenStudio.
