Python新手在这里！我在Heroku上部署脚本时遇到问题 - 它在本地工作正常，但是在Heroku上它会给我这个日志：

主要错误是AttributeError。
搜索周围，其他人在Django上遇到这个错误，但解决方案似乎只适用于Django，我的脚本没有使用它 - 它确实使用Python API封装器来实现Goodreads（找到here ）。 我稍微修改了一下代码，试图列出实例的属性。
print(dir(gc))
gc是GoodreadsClient实例，它打印了这个属性列表
[＆＃39; doc ＆＃39;，＆＃39; init ＆＃39;，＆＃39; 模块 ＆＃39;，＆＃39; auth_user＆＃39;，＆＃39; authenticate＆＃39;，＆＃39; author＆＃39;，＆＃39; base_url＆＃39;，＆＃39; book＆＃39;， ＆＃39; book_review_stats＆＃39;，＆＃39; client_key＆＃39;，＆＃39; client_secret＆＃39;，＆＃39; find_author＆＃39;，＆＃39; find_groups＆＃39;，＆＃39; group＆ ＃39;，＆＃39; list_comments＆＃39;，＆＃39; list_events＆＃39;，＆＃39; owned_book＆＃39;，＆＃39; query_dict＆＃39;，＆＃39; recent_reviews＆＃39;，＆ ＃39; request＆＃39;，＆＃39; request_oauth＆＃39;，＆＃39; review＆＃39;，＆＃39; search_books＆＃39;，＆＃39; user＆＃39;]
与API包装器的文档一致。但是一旦部署，就打印
[＆＃39; doc ＆＃39;，＆＃39; init ＆＃39;，＆＃39; 模块 ＆＃39;，＆＃39; auth_user＆＃39;，＆＃39; authenticate＆＃39;，＆＃39; author＆＃39;，＆＃39; base_url＆＃39;，＆＃39; book＆＃39;， ＆＃39; book_review_stats＆＃39;，＆＃39; client_key＆＃39;，＆＃39; client_secret＆＃39;，＆＃39; find_groups＆＃39;，＆＃39; group＆＃39;，＆＃39; list_comments＆ ＃39;，＆＃39; list_events＆＃39;，＆＃39; owned_book＆＃39;，＆＃39; query_dict＆＃39;，＆＃39; recent_reviews＆＃39;，＆＃39; request＆＃39;，＆ ＃39; request_oauth＆＃39;，＆＃39; review＆＃39;，＆＃39; user＆＃39;]
缺少＆＃39; find_author＆＃39;和＆＃39; search_books＆＃39;属性（search_books是在heroku上给出错误一次的属性）。 导致这些属性丢失的原因是什么？有解决方法吗？
我的script，如果有帮助的话。
