如何像在 pip 中一样在 uv 中添加 --install-option 键和值

  • 772

我正在使用uv作为我的 Python 包管理器，并且我有以下命令来安装包pip：

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

我的 uv 版本是0.6.14，而 Python 版本是3.10。

我怎样才能实现相同的安装uv？

我尝试过

  1. uv 添加包

    $ uv add pygraphviz

    输出

    × 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]`

    帖子建议在libgraphviz-dev系统范围内安装，但由于权限限制，这对我来说不是一个选择。因此我需要知道如何指定库路径，以便将必要的文件放在我可以访问的目录中。

  2. uv 兼容 pip 命令

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

    输出

    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'.

    我认为这样做可以达到目的：

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

    CFLAGS代表 C 编译器标志。-I/myfolder/include/graphviz告诉编译器头文件（.h）。

    LDFLAGS代表 Linker Flags。-L/myfolder/lib/graphviz告诉链接器库（.so）。
