Adding blpapi and a custom package to poetry

[gt6989b]

I am working with poetry in Python as a package manager. I would like to add requirements to blpapi and to another custom in-house package, located on a network drive.

---

Bloomberg Library

For blpapi, the instructions on the Bloomberg API Library Support page note that to install it we need to run the shell command

> python -m pip install --index-url=https://bcms.bloomberg.com/pip/simple blpapi

and I am somewhat puzzled how to add that to poetry.

---

Custom Package

For the custom package, if I execute

dkreslavskiy_sym@SYMLT097 c:\src\RiskTool
> poetry shell
Spawning shell within C:\Users\dkreslavskiy_sym\AppData\Local\pypoetry\Cache\virtualenvs\risktool-G_6ObRAZ-py3.10

(risktool-py3.10) dkreslavskiy_sym@SYMLT097 c:\src\RiskTool
> which pip
/c/Users/dkreslavskiy_sym/AppData/Local/pypoetry/Cache/virtualenvs/risktool-G_6ObRAZ-py3.10/Scripts/pip

(risktool-py3.10) dkreslavskiy_sym@SYMLT097 c:\src\RiskTool
> pip install T:\IT\Carbon\python-client\sym-carbon-1.10.1.zip
Processing t:\it\carbon\python-client\sym-carbon-1.10.1.zip
...
Successfully installed symmetry-carbon-1.10.1

It installs successfully. However, when I try to add it as a poetry requirement, I get the following error:

dkreslavskiy_sym@SYMLT097 c:\src\RiskTool
> poetry add T:\IT\Carbon\python-client\sym-carbon-1.10.1.zip

      153│
      154│             return

Not sure how to get around that.

Thank you very much for your help. I have also posted this question on Stack Overflow.
