Python 2.7 我在使用flask SQL alchemy提交到sqlite3时遇到导入错误

奇怪的是，我只是尝试使用flask sqlalchemy更新sqlite3数据库中的一个值

anime = Anime.query.get(2)
anime.finished=2
db.session.add(anime)
db.session.commit()

在提交之前一切正常，然后我得到一个“ImportTerror:没有名为pycharm\u re的模块”

是的，我正在使用PyCharmCE IDE，但没有PyCharm基导入。当我在终端中尝试此操作时，导致了相同的错误

最后，我发现它可能与嗖嗖炼金术有关，我以前在models.py中有2个嗖嗖指数（app，SomeClass）时遇到过这个错误

我在PyCharmCE中使用Python2.7.3，在Terminal中使用2.7.5。系统是OSX10.9.2。 整个错误日志：

似乎是因为我在使用whoosh_index（）函数运行后添加了第二行whoosh_index（），然后不允许进行任何编辑，我将在返回后进行更多尝试。代码中的另一个问题是您再次将

anime

对象添加到会话中。没用。获取实体时，它们已附加到默认的

db.session

。只有在创建新实体时，才需要调用

all

。
