poetry lock / poetry install running into issues locally

[andrew-p-morris-er]

I'm trying to update virtual environments on my local machine for local development using poetry, but can't debug the following error when trying to run poetry lock / poetry install:

(probmodels-py3.10) (base) andrewmorris@Andrews-MacBook-Pro probmodels % poetry lock
Updating dependencies
Resolving dependencies... (0.3s)

HTTPSConnectionPool(host='github.com', port=443): Max retries exceeded with url: /EntityRisk/erutils.git/info/refs?service=git-upload-pack (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)')))

Indeed the problem is specific to the github dependency, which in this case is erutils, specified in pyproject.toml as follows:

[tool.poetry.dependencies]
python = "^3.8"
scipy = "^1.9.3"
numpy = "^1.23.4"
pandas = "^1.5.1"
scikit-learn = "^1.1.3"
cmdstanpy = "^1.0.8"
arviz = "^0.14.0"
plotly = "^5.11.0"
erutils = {git = "https://github.com/EntityRisk/erutils.git", branch = "sort-categorical-scatter-points"}

Wondering if others have faced this problem or if they've found a solution. So far the basic fixes I've tried:

• Removing the github dependencies - this works, but the dependencies are needed.
• Pointing to main for the github dependency - this doesn't work
• clean install of poetry - this doesn't work

It seems like others have faced similar difficulties before, but the solutions discussed in these threads did not work for me either - likely owing to their having issues that (1) were slightly different and (2) being due to use of a VPN. (2) doesn't seem to be the issue in this case, since I get this error whether I'm on or off the VPN.

Any thoughts welcome and appreciated.

Also note - this isn't urgent, as I'm not in dire need of being able to work on probmodels locally.

Did you use poetry add to update the TOML file? When I did so, I got a different output from you:

erutils = {git = "https://github.com/EntityRisk/erutils.git", rev = "sort-categorical-scatter-points"}

I did try with your syntax and it still seems to work.

Can you install directly via pip without going through poetry?

[andrew-p-morris-er]

Thanks @jeff-m-sullivan ! I initially updated the TOML file manually, but I still get the error after re-adding erutils via poetry add.

And yes, I can install directly via pip so it appears to be specific to poetry

I did manage to sort this out, at long last. The issue was Python's ssl certificates being out of date. Resolved via this handy point-and-click solution: python-poetry/poetry#745 (comment)
