DjangoCMS 插件 OperationalError at /en/admin/cms/page/add-plugin/ - 没有这样的表：cmsplugin_soundcloud_soundcloud

如何解决DjangoCMS 插件 OperationalError at /en/admin/cms/page/add-plugin/ - 没有这样的表：cmsplugin_soundcloud_soundcloud

我正在使用 djangoCMS。我正在尝试让 SoundCloud plugin 工作。在我可以处理的一些修复之后，我遇到了这个错误：

    OperationalError at /en/admin/cms/page/add-plugin/ 
no such table: cmsplugin_soundcloud_soundcloud

我无法理解。在将实例保存为插件时，这会出现在 DjangoCMS 前端的编辑模式中。

以下是我所做的修复：

在/Lib/site-packages/cmsplugin_soundcloud/models.py 将 from urllib import urlencode 更改为 from urllib.parse import urlencode 将 from urllib2 import urlopen 更改为 from urllib.request import urlopen 将 from urlparse import urlsplit,urlunsplit,parse_qsl 更改为 from urllib.parse import urlsplit,parse_qsl

在/Lib/site-packages/cmsplugin_soundcloud/cmsplugins.py
添加render_template = "cmsplugin_soundcloud.html "

我不确定问题是由我所做的修复触发的，也不确定是否可以应用快速修复。

波纹管是回溯。 谢谢。
