 2  > If you are here because you are trying to build Deluge client, before proceeding, please check build instructions in [[Deluge]] regarding the location of the python virtual environment folder (`.venv` in this case).
 3  
 4  To build a debug version with python bindings, first (re)build and (re)install the debug target:
 5  
 6  ```bash
 7  b2 crypto=openssl cxxstd=14 debug
 8  sudo b2 install --prefix=/usr/local
 9  ```
10  
11  Then check [[Modern Python Tools|Python Tools]], and install `uv`:
12  
13  ```bash
14  curl -LsSf https://astral.sh/uv/install.sh | sh
15  ```
16  
17  Then create a virtual env indicating the python version you want to use:
18  
19  ```bash
20  uv venv --python 3.12.3
21  ```
22  
23  It will create a folder called `.venv` in your current folder. 
24  
25  Activate the environment:
26  
27  ```bash
28  source .venv/bin/activate
29  ```
30  
31  > Make sure you have the correct path to the `.venv` folder, If you are not in the folder directly containing `.venv` folder.
32  
33  Then, install `setuptools`:
34  
35  ```bash
36  uv pip install setuptools
37  ```
38  
39  Also make sure that you have:
40  
41  ```bash
42  sudo apt install libboost-python-dev
43  ```
44  
45  as specified in [libtorrent python binding](http://www.libtorrent.org/python_binding.html) in *prerequisites*.
46  
47  Finally, from `bindings/python` run:
48  
49  ```bash
50  python setup.py build_ext --b2-args=variant=debug install
51  ```
52  
53  Python bindings should be ready to use. You should be able to test it with:
54  
55  ```bash
56  python
57  Python 3.12.3 (main, Sep 11 2024, 14:17:37) [GCC 13.2.0] on linux
