显然，在我看来tweets表中存在问题，但我不知道它可能是什么，因为该应用程序在开发中和生产中的heroku上工作。
以下是该表的架构：
create_table "tweets", :force => true do |t|
t.integer "authorization_id"
t.string "name"
t.string "screen_name"
t.string "uid"
t.integer "tid"
t.string "tid_string"
t.string "text"
t.integer "followers_count"
t.integer "statuses_count"
t.integer "friends_count"
t.integer "retweets_count"
t.datetime "created_at"
t.datetime "updated_at"
end
add_index "tweets", ["authorization_id"], :name => "index_tweets_on_authorization_id"
add_index "tweets", ["tid"], :name => "index_tweets_on_tid"
add_index "tweets", ["tid_string"], :name => "index_tweets_on_tid_string"
转推：
create_table "retweets", :force => true do |t|
t.integer "entry_id"
t.string "twitter_username"
t.datetime "tweet_date"
t.datetime "created_at"
t.datetime "updated_at"
t.string "twitter_user_id_str"
t.string "name"
t.integer "twitter_user_id"
t.integer "tweet_id"
t.string "tweet_id_str"
end
add_index "retweets", ["entry_id"], :name => "index_retweets_on_entry_id"

我认为这是由Heroku和SQLite上的PostgreSQL之间的差异引起的。我会切换到PostgreSQL。即使你让它工作，你可能会在以后遇到问题。
我安装了PostgreSQL，非常简单。

所以我今天早上安装了postgres并尝试了db:pull但它仍然失败了 - 但是，postgres更有启发性。它不是retweets表失败，而是authorizations。我错误地在一段时间后输入了一列last__name并忘了删除它（我已经添加了last_name）。一旦我从数据库中清除了它，db:pull再次处理sqlite和postgres。
