我正在尝试将我正在编写的 Python 金字塔应用程序从一台服务器移动到另一台服务器。我从源代码管理中检查了代码并运行 apython setup.py develop来准备环境，但是当我尝试运行时，pserve development.ini我得到以下回溯：

2013-02-27 20:38:20,269 INFO  [pyramid_scss][MainThread] adding asset path /home/pgrace/repos/Asterisk-WebApps/Cedar-Root/opt/cedar/cedar/assets/scss

    scss.LOAD_PATHS = ','.join([scss.LOAD_PATHS, ','.join(load_paths)])
AttributeError: 'module' object has no attribute 'LOAD_PATHS'

现在，我可以说问题出在 pyramid_scss，但据我所知，它引用的代码很好，就好像module该类不包含 LOAD_PATHS 指令一样。我试图弄清楚它指的是哪个模块，以便我可以追踪我是否缺少依赖项或其他东西。有谁知道我将如何确定module参考指向的位置，以便我可以检查该代码？

编辑：错误出现在includeme定义中，每当一个特定于金字塔的包被实例化时，它就会自动包含在我读过的内容中？也许？无论如何，它说 scss.LOAD_PATHS 不存在，是的，但是在任何一个pyramid_scss或pyScss包中都没有 scss 类，这让我想知道是否还有其他一些正在后期绑定的类。

def includeme(config):
    load_paths, static_path = _get_import_paths(config.registry.settings)
    scss.LOAD_PATHS = ','.join([scss.LOAD_PATHS, ','.join(load_paths)])
    scss.STATIC_ROOT = static_path
    config.add_renderer('scss', renderer_factory)

pyScss 中的Scss类确实包含一个 LOAD_PATHS 指令，但我看不到对象 scss 绑定到 Scss 类定义的位置。我想知道def includeme上面是否缺少一些可能是答案的一部分，但随后它引出了一个问题——这在另一台机器上工作正常，为什么现在中断？还有一些东西我只是没有接受。

通过检查scss包的代码，看起来LOAD_PATHS全局变量可能已从__init__.py移至config.py.

因此，如果您想尝试修复pyramid_scss应用程序，可以将第 88 行更改pyramid_scss/__init__.py为：

scss.config.LOAD_PATHS = ','.join([scss.config.LOAD_PATHS, ','.join(load_paths)])

最后一行告诉您哪个模块受到影响：

    scss.LOAD_PATHS = ','.join([scss.LOAD_PATHS, ','.join(load_paths)])
AttributeError: 'module' object has no attribute 'LOAD_PATHS'

所以scss模块没有LOAD_PATHS属性。
