How to add --install-option key and value in uv like in pip

I'm using uv as my Python package manager, and I have the following command to install a package with pip:

$ pip install pygraphviz --install-option="--include-path=/usr/include/graphviz" \ 
--install-option="--library-path=/usr/lib/graphviz"

My uv version is 0.6.14, and Python version is 3.10.

How can I achieve the same installation in uv?

What I have tried

  1. uv add package

    $ uv add pygraphviz

    Output

    × Failed to build `pygraphviz==1.14`
├─▶ The build backend returned an error
╰─▶ Call to `setuptools.build_meta.build_wheel` failed (exit    status: 1)

  hint: This error likely indicates that you need to install a  library that provides "graphviz/cgraph.h" for `[email protected]`

    The post suggests installing libgraphviz-dev system-wide, but this is not an option for me due to permission restrictions. That’s why I need to know how to specify the library path, so I can place the necessary files in a directory where I have access.

  2. uv compatible pip command

    $ uv pip install pygraphviz --install-option="--include-path=/myfolder/include/graphviz" \ 
--install-option="--library-path=/myfolder/lib/graphviz"

    Output

    Output:

error: unexpected argument '--install-option' found

  tip: a similar argument exists: '--reinstall'

Usage: uv pip install --reinstall <PACKAGE|--requirements <REQUIREMENTS>|--editable <EDITABLE>|--group <GROUP>>

For more information, try '--help'.
Solution

  • I think this do the trick:

    CFLAGS="-I/myfolder/include/graphviz" LDFLAGS="-L/myfolder/lib/graphviz" uv pip install pygraphviz

    CFLAGS stands for C Compiler Flags.-I/myfolder/include/graphviz tells the compiler for header files (.h).

    LDFLAGS stands for Linker Flags. -L/myfolder/lib/graphviz tells the linker for libraries (.so).
