我正在Python 2.7使用Mac OS X Lion 10.7.5.
我最初在MySQLdb使用两者进行安装pip-2.7 install MySQL-python以及下载然后运行python2.7 setup.py build和python2.7 setup.py install. 我使用 32 位和 64 位安装MySQL和相应的体系结构尝试了这些不同的方法，但无济于事。
我的解决方案是安装Macports. 然后我使用 Macports安装MySQL和MySQL-python( )。MySQLdb
我Wing IDE用于开发代码，所以我切换到 Macports 版本的Python- 导入MySQLdb作品。python我还将 Python 的默认终端版本切换到这个 Macports 版本，并通过从命令行调用来验证它是默认版本——启动了正确的版本。
所以现在的问题是：我正在使用scrapy来抓取电影网页以获取信息。我的管道将抓取的数据定向到使用前面提到的MySQLdb模块的数据库。当我转到命令行，cd进入我的项目并运行scrapy crawl MySpider时，我收到以下错误：
raise ImportError, "Error loading object '%s': %s" % (path, e)
ImportError: Error loading object 'BoxOfficeMojo.pipelines.BoxofficemojoPipeline': No module named MySQLdb.cursors
我已经检查并确保我可以从 python2.7 shell 导入 MySQLdb.cursors，所以我认为使用哪个版本的 Python scrapy 存在问题......

我将此添加到代码中以希望修复问题 - 它是py27-mysql( MySQLdb) 的位置，但返回相同的错误：
