Question

我刚刚更新到Haystack第2版，并且在尝试进行之前使用1.7.2的搜索时遇到了ImportError。

cannot import name site

  3. from haystack import site

Exception Type: ImportError at /search/
Exception Value: cannot import name site

是的，这是因为在Haystack的2.0版本中，haystack.site被删除了。 Haystack API在这个新版本中经历了一些重大变化，但仍然没有稳定版本。使用1.2.7仍然是Django和基于文档的搜索引擎的特色版本。

您可以阅读entire documentation here有关如何将1.x版本迁移到2.x

的信息

希望它有所帮助！：）
