可以使用以下代码获取已安装包的Conda-Forge URL：

import conda.config as cc

def get_conda_forge_url(package_name):
    channel_urls = cc.get_channels()
    for url in channel_urls:
        if url.startswith("https://conda.anaconda.org/conda-forge/"):
            forge_url = url.replace("https://conda.anaconda.org/conda-forge/", "https://github.com/conda-forge/")
            package_info = cc.get_package_info(package_name, url=forge_url)
            if package_info is not None:
                return forge_url + "/tree/master/recipes/" + package_info['name']
    return None

使用方式：

get_conda_forge_url('numpy')

输出：

'https://github.com/conda-forge/numpy-feedstock/tree/master/recipe'
