scripts install VEN agent

[bbartling]

Could I get a tip for how to install the agent with scripts install style? (not modular volttron) I also did a pip install inside the VOLTTRON venv prior to this and noticed some error in the crypto library:

vctl install volttron-openadr-ven \
--tag openadr \
--agent-config volttron-openadr-ven/config_example1.json

Errors out on:

(volttron) geb@volttron:~/volttron$ vctl install volttron-openadr-ven \
> --tag openadr \
> --agent-config volttron-openadr-ven/config_example1.json

Hi Ben, this looks like a cryptography depdency issue which recently got resolved in a PR I submitted to openleadr that got merged last month. I recommend installing the latest from openleadr, 0.5.27 which should have the fix. Once you have that version of openleadr, you should be able to install the agent without running into this error.

Hi Mark, I did a pip install openleadr --upgrade

Which did a appear to update openleadr, this is a pip list on my machine:

But when I run afterword's : vctl install volttron-openadr-ven --tag openadr --agent-config volttron-openadr-ven/config_example1.json

This will still throw an error about the cryptography library:

Thanks for any tips to try

@bbartling We have a prerelease version that was released last week that addresses this issue. Please try installing that version using pip install volttron-openadr-ven==1.0.1a0. See https://pypi.org/project/volttron-openadr-ven/1.0.1a0/

Hi Mark,

Was this ever fixed? Am running into the same problem 'cryptography==37.0.4'

[bonicim]

@bbartling This was fixed in monolith volttron (see this PR). However, the modular volttron equivalent (i.e. this repo) didn't get the change. I can look into this. In this meantime, to get over this issue, you can update the pyproject.toml file with this change:

# Current
[tool.poetry.dependencies]
python = ">=3.8,<4.0"
volttron = "^10.0.2rc0"
openleadr = "0.5.27"
cryptography = ">=36.0.1,<37.0.0"

# Updated
[tool.poetry.dependencies]
python = ">=3.8,<4.0"
volttron = "^10.0.2rc0"
openleadr = "0.5.27"
cryptography="37.0.4"

See this line of code.
