最近在写一个CMDB的项目，遇到drf与django版本问题...

错误如下：

AttributeError at /

解决方案如下：

打开drf源码目录下的 compat.py 文件，我的路径是： D:CodePythonAutoCMDBViewervenvLibsite-packages est_frameworkcompat.py 定位到157行代码进行修改：

try:
    import markdown

    if markdown.__version__ <= ‘2.2‘: # 将version修改为__version__即可
        HEADERID_EXT_PATH = ‘headerid‘
        LEVEL_PARAM = ‘level‘
    elif markdown.__version__ < ‘2.6‘: # 将version修改为__version__即可
        HEADERID_EXT_PATH = ‘markdown.extensions.headerid‘
        LEVEL_PARAM = ‘level‘
    else:
        HEADERID_EXT_PATH = ‘markdown.extensions.toc‘
        LEVEL_PARAM = ‘baselevel‘

    def apply_markdown(text):
        """
        Simple wrapper around :func:`markdown.markdown` to set the base level
        of ‘#‘ style headers to <h2>.
        """
        extensions = [HEADERID_EXT_PATH]
        extension_configs = {
            HEADERID_EXT_PATH: {
                LEVEL_PARAM: ‘2‘
            }
        }
        md = markdown.Markdown(
            extensions=extensions, extension_configs=extension_configs
        )
        md_filter_add_syntax_highlight(md)
        return md.convert(text)
except ImportError:
    apply_markdown = None
    markdown = None
