python-3.x - 如何在conda环境中安装pybel？

        DEPRECATION: Uninstalling a distutils installed project (certifi) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

运行 python 提示符并尝试导入 pybel，但它内部并没有真正的 API(例如 readfile ):
