因为我导入import_export相关的类和motheds，我找不到原因。

Because I import the import_export relevant class and motheds, I can't find out the reason.

推荐答案

请检查您是否有文件： __ init __。py C：\Python27\lib\site-packages\import_export\

Please check if You have file: __init__.py in C:\Python27\lib\site-packages\import_export\

如果您使用 virtualenv 它的接缝尚未被激活。

If You are using virtualenv it seams that it hasn't been activated.

另外你有和错误在这里：

Also You have and error here:

class AuthorAdmin(ImportExportModelAdmin):
    search_fields = ('author', 'title',)
    list_display = ('author', 'title',)
    resource_class = AuthorResource

因为ImportExportModelAdmin已经有ModelAdmin：

because ImportExportModelAdmin already has ModelAdmin:

class ImportExportModelAdmin(ImportExportMixin, admin.ModelAdmin):
    """
    Subclass of ModelAdmin with import/export functionality.
    """
