Trouble with git link dependency rooted in subfolder

[ashnair1]

My goal is to add this forked library as a dependency to my project. Previously with pip I was able to install the library via

pip install "git+https://github.com/ashnair1/cocoapi.git#egg=pycocotools&subdirectory=PythonAPI"

Essentially I would like to do the same with poetry. #1221 added a feature to add git links as dependencies so I did try the following:

poetry add -vvv git+https://github.com/ashnair1/cocoapi.git#egg=pycocotools&subdirectory=PythonAPI

But this didn't work and resulted in the following stack trace.

So how can I add the library as a project dependency?

Hello @ashnair1 ,

what you try is to install a package from a subfolder within a git repository. This is not supported at the moment by poetry. Some links you can follow:

• Dependency rooted in a subfolder of a GIT repository #755
• support git subfolder poetry-core#9 (comment)
• Better git handling poetry-core#192
