mysql - 将 MySQL 与 dev_appserver (Google App Engine) 和 Google SQL 服务一起使用

Question

我正在使用 Google App Engine 和 Google SQL 服务，并希望使用该选项

dev_appserver.py --mysql_user=username myapp

为了将本地 MySQL 数据库用于开发目的，以及在 prod 环境中使用 SQL 服务。

我已安装并运行 MySQLdb:

/usr/bin>>python
Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
>>> 

但是，当我运行 dev_appserver 命令时，我收到以下错误:

zipimporter('/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg', 'MySQLdb/')
ERROR    2011-09-12 09:34:53,541 rdbms_mysqldb.py:90] The rdbms API is not available because the MySQLdb library could not be loaded.

我已验证 MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg 位于 (/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site -packages/) 并且它是可访问的。

知道是什么导致了这个错误吗？

穷人的解决方案。

我加了

“导入MySQLdb”

在 dev_appserver.py 中。

现在可以了。
