Python flask.ext.mysql 已弃用?
当我运行 from flask.ext.mysql import MySQL 时，我收到警告 Importing flask.ext.mysql is deprecated，改用flask_mysql.
When I run from flask.ext.mysql import MySQL I get the warning Importing flask.ext.mysql is deprecated, use flask_mysql instead.
所以我使用pip install flask_mysql安装了flask_mysql，安装成功但是当我运行from flask_mysql import MySQL时我得到错误No module named flask_mysql.在第一个警告中，我也得到 Detected 扩展名为flaskext.mysql，请将其重命名为flask_mysql.旧形式已弃用..format(x=modname), ExtDeprecationWarning.你能告诉我我应该如何将它重命名为flask_mysql吗?提前致谢.
So I installed flask_mysql using pip install flask_mysql,installed it successfully but then when I run from flask_mysql import MySQL I get the error No module named flask_mysql. In the first warning I also get Detected extension named flaskext.mysql, please rename it to flask_mysql. The old form is deprecated.
.format(x=modname), ExtDeprecationWarning. Could you please tell me how exactly should I rename it to flask_mysql?
Thanks in advance.

flask.ext. 是一种已弃用的模式，广泛用于较旧的扩展和教程中.警告告诉你用直接导入替换它，它猜测是 flask_mysql.然而，Flask-MySQL 正在使用一种更加过时的模式，flaskext..除了说服维护者发布修复它的新版本之外，您无能为力.from flaskext.mysql import MySQL 应该可以工作并避免警告，尽管最好将包更新为使用 flask_mysql 代替.
flask.ext. is a deprecated pattern which was used prevalently in older extensions and tutorials. The warning is telling you to replace it with the direct import, which it guesses to be flask_mysql. However, Flask-MySQL is using an even more outdated pattern, flaskext.. There is nothing you can do about that besides convincing the maintainer to release a new version that fixes it. from flaskext.mysql import MySQL should work and avoid the warning, although preferably the package would be updated to use flask_mysql instead.
