Hi all,
I’m new to Tryton. After trying Odoo, I would like to try Tryton. This Software seems interesting and promising from my perpective. However, after I clone the repository, I don’t see any `requirements.txt` or `Pipfile`.
Do the developer use virtual environment such as `virtualenv` or `pipenv`?
I saw the list of requirements in the documentation. But it would be good if there is a `Pipfile` in the repository.

The dependencies are in the setup.py so you just need to install the package to get all the dependencies.

Hi Cédric,
thanks for the reply. Yes, the dependencies are defined in the setup.py. So, it does not use the virtual environment concept.

I do not see why you say that. `requirements.txt` and `Pipfile` are for specific deployment, see [setup.py vs requirements.txt · caremad](https://caremad.io/posts/2013/07/setup-vs-requirement/) while Tryton is a distributed package.
Both dependencies concepts are not linked in any way to the virtual environment concept. You can install Tryton for development in a virtual environment by running `python setup.py develop`.

Thanks for the link Cédric. I was wrong since I thought the `setup.py` will install the dependencies globally. I’ve just tested running `python setup.py install` and the libs are installed in my virtual env folder.
So what is the difference between the parameter `install` and `develop` after setup.py?

`install` is copying the source into `lib/pythonx.y/site-packages/`
`develop` does not copy the source but store a link in `easy-install.pth` to point to the current folder.
So `develop` is useful if you are working actually on the source code of Tryton.
