module 'markdown' has no attribute 'version'

最近在寫一個(gè)CMDB的項(xiàng)目，遇到drf與django版本問題...

錯(cuò)誤如下：

AttributeError at /
module 'markdown' has no attribute 'version'
Request Method: GET

Django Version: 2.1.1
Exception Type: AttributeError

idna==2.7

pycparser==2.18
PyMySQL==0.9.2
pytz==2018.5
six==1.11.0

解決方案如下：

打開drf源碼目錄下的 compat.py 文件，我的路徑是： D:\Code\Python\AutoCMDBViewer\venv\Lib\site-packages\rest_framework\compat.py 定位到157行代碼進(jìn)行修改：

try:
    import markdown

    if markdown.__version__ <= '2.2': # 將version修改為__version__即可
        HEADERID_EXT_PATH = 'headerid'
        LEVEL_PARAM = 'level'
    elif markdown.__version__ < '2.6': # 將version修改為__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 <h3>.
        """
        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
