Question

很奇怪，我只是尝试使用flask-sqlalchemy更新sqlite3数据库中的值。

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

在提交之前一切正常，然后我得到了一个＆＃34; ImportError：没有名为pycharm_re＆＃34;的模块。

是的，我使用的是PyCharmCE IDE，但没有任何PyCharm基础导入。当我在终端中尝试这个时，导致了同样的错误。

最后，我发现它可能是关于嗖嗖 - 炼金术，我在models.py中有2个whoosh.whoosh_index（app，SomeClass）之前遇到过这个错误。

我在PyCharmCE中使用Python 2.7.3，在终端中使用2.7.5。系统是OS X 10.9.2。整个错误日志：
