--no-install-project being ignored during a sync

[VERBOSE-01]

Question

I'm trying a partial installation (all dependencies, except my project) using the --no-install-project flag but unfortunately, uv still tries to install the project itself.

Tree

> my_personal_project
--> # src folders and files
--> pyproject.toml
--> .python-version

Terminal

PS C:\Users\verbose\Desktop\my_personal_project> uv sync --no-install-project
Using CPython 3.13.2 interpreter at: C:\Users\verbose\AppData\Local\Programs\Python\Python313\python.exe
Creating virtual environment at: .venv
⠋ my_personal_project==1.3.1

.python-version

3.13.2

pyproject.toml

[project]
name = "my_personal_project"
version = "1.3.1"
authors = [
    { name = "VERBOSE", email = "[email protected]" },
]
requires-python = ">=3.10"
dependencies = [
    "beautifulsoup4==4.12.2",
    "openpyxl==3.1.5",
    # ... others
]

[dependencies-groups]
dev = [
    "pytest==6.2.5",
    "ruff==0.11.0",
]

Some context

I'm dropping requirements.txt and requirements-dev.txt in favor of uv.lock. It means that I have no reqs files anymore and the pyproject.toml was created manually (before installing uv).

Platform

Windows 10

Version

0.6.7

It looks like we're resolving your project (which we'd need to do for dependency resolution) but we may not be installing it. Can you please create a complete reproduction -- like a GitHub repository we can clone and a set of commands we can run?

Many thanks for taking the time. I'm afraid I won't be able to make a MRE because it isn't an issue for me anymore. Maybe it's completely random but I just did the following steps (see below) and uv installed all dependencies and created a uv.lock successfully:

1. run $env:HTTPS_PROXY = "http://..." since I'm behind a proxy (as suggested here)
2. deleted the old .venv (created earlier by uv sync --no-install-project)
3. replaced [dependencies-groups] with dependency-groups in the pyproject.toml
4. created a new .venv and this time with uv venv --seed (as suggested here because my pip install was ignoring .venv)
5. re run uv sync (without any flag this time)

Vscode terminal (powershell)

PS C:\Users\verbose\Desktop\my_personal_project> $env:HTTPS_PROXY = "http://..."

Sorry again and thanks for this tool. A game changer, honestly ;)
