获取依赖路径的最简单方法是：

from conans import ConanFile # for type hinting

# conan create
boost: ConanFile = self.dependencies.build["boost"]
boost.package_folder

但它并不总是有效的

• self.dependencies在不计算依赖关系树时为none，例如在conan buildhttps://github.com/conan-io/conan/issues/10535期间，您可以使用以下变通方法：

# conan build (hacky)
self.deps_cpp_info["boost"].build_paths[0]

• 它可能不是在所有步骤中都可用（我没有详细检查）

获取这些信息最可靠的方法是从conanbuildinfo.txt读取if--这个文件是在安装阶段创建的，你可以使用不同的生成器，比如-g json，以不同的格式使用它。

from conans.client.generators import TXTGenerator
with open("conanbuildinfo.txt", "r") as handle:
    contents = handle.read()
deps_cpp_info, deps_user_info, deps_env_info, user_info_build = TXTGenerator.loads(contents)

我在代码中找到的最后一种方法（这可以简化，但这就是我现在所能提供的）：

import sys

import conans.errorsc
import conans.cli.exit_codes
from conans import ConanFile

from conans.client.cache.cache import ClientCache
from conans.client.conan_api import Conan
from conans.model.ref import PackageReference
from conans.paths.package_layouts.package_editable_layout import PackageEditableLayout

try:
    conan_api, _, _ = Conan.factory()
except conans.errors.ConanMigrationError:
    sys.exit(conans.cli.exit_codes.ERROR_MIGRATION)
except conans.errors.ConanException as error:
    sys.exit(conans.cli.exit_codes.ERROR_GENERAL)

def _discover_package_path(dependency_name: str) -> str:
    """Returns a package folder in local conan cache for specified dependency.

    data, _ = conan_api.info(reference_or_path="conanfile.py")
    node = next(node for node in data.nodes if node.name == dependency_name)
    cache = ClientCache(conan_api.cache_folder, conan_api.out)
    layout = cache.package_layout(node.ref, node.conanfile.short_paths)
    if isinstance(layout, PackageEditableLayout):
        return node.conanfile.package_folder
    else:
        return layout.package(PackageReference(node.ref, node.package_id))

# _discover_package_path("cmake")
