[Python] Managing sub packages with poetry

I have an old Django project, which uses PIP for package management. What Im trying is to migrate it to use Poetry instead of PIP.

My project structure is like so:

main-project-root/
├── requirements/
│ └── dev.txt # pip-based dev dependencies
│
├── src/
│ └── myProj/
│ ├── myProj/ # This is main Django app
│ │ ├── __init__.py
│ │ ├── settings.py
│ │ ├── urls.py
│ │ └── wsgi.py
│ └── manage.py # Main project's manage.py
│
├── lib/
│ ├── mySubProj1/
│ │ ├── pyproject.toml # Subproject-specific dependencies
│ │ ├── poetry.lock
│ │ ├── mySubProj1/ # Django app package inside
│ │ │ ├── __init__.py
│ │ │ ├── settings.py
│ │ │ └── ...
│ │ └── manage.py
│ │
│ ├── mySubProj2/
│ │ ├── pyproject.toml
│ │ ├── poetry.lock
│ │ ├── mySubProj2/
│ │ └── manage.py
│ │
│ └── mySubProj3/
│ ├── pyproject.toml
│ ├── poetry.lock
│ ├── mySubProj3/
│ └── manage.py
│
├── pyproject.toml # Root pyproject for main project
├── poetry.lock
└── README.md


I have added all the needed packages into a separate poetry config file for each sub-project. My idea is when i execute: poetry install from the main project destination - to install all the sub-project pyproject.toml poetry configurations.

However, I keep hitting an error:

Installing the current project: main-project (0.1.0) Error: The current project could not be installed: No file/folder found for package main-project If you do not want to install the current project use --no-root. If you want to use Poetry only for dependency management but not for packaging, you can disable package mode by setting package-mode = false in your pyproject.toml file. If you did intend to install the current project, you may need to set packages in your pyproject.toml file.
​

This is how my main pyproject.toml looks like:

[project]
name = "main-project"
version = "0.1.0"
description = ""
authors = [
{name = "Your Name",email = "you@example.com"}
]
readme = "README.md"
requires-python = ">=3.8"
package-mode = false

[tool.poetry.dependencies]
mySubProj1 = {path = "lib/mySubProj1", develop = true}


[build-system]
requires = ["poetry-core>=1.0.0,<2.0.0"]
build-backend = "poetry.core.masonry.api"


And this is how my subProj1 pyproject.toml looks like:

[project]
name = "mySubProj1"
version = "0.1.0"
description = ""
authors = [
{name = "Test Test",email = "test@gmail.com"}
]
license = {text = "Apache License 2.0"}
readme = "README.rst"
requires-python = ">=3.8"

[tool.poetry]
name = "mySubProj1"
version = "0.1.0"
description = ""
authors = ["Test test <test@gmail.com>"]
license = "Apache-2.0"
readme = "README.rst"
packages = [{include = "mySubProj1"}]

[tool.poetry.dependencies]
python = "^3.8"
six = ">=1.17.0,<2.0.0"

[build-system]
requires = ["poetry-core>=1.0.0,<2.0.0"]
build-backend = "poetry.core.masonry.api"
