没有名为markdown App Engine的模块

Question

我在app引擎中的目录结构是这样的:

project 
    app.yaml
    main.py
    lib
      markdown
        markdown_files 

降价正在导入中main.py的from lib.markdown import markdown .此时,dev服务器开始给我以下堆栈跟踪.我想知道这里出了什么问题!我在lib中有一个init .py.

UPDATE1

我相信这个问题是导入Python模块和PyImport_ImportModuleEx用于gedit插件的骗局

答案:

如果你想使用markdown而不修改它,那么你将不得不把它放在Python库所期望的地方,比如在site-packages /中.否则,您必须修改它以使用相对导入而不是绝对导入.

更新2 我通过在app引擎中修改我的sys.path解决了这个问题:

sys.path.append(os.path.join(os.path.dirname(file),'lib'))

感谢Murat的帮助,

我相信这个问题是用 PyImport_ImportModuleEx 为 gedit 插件导入 Python 模块的欺骗

答案：

如果你想使用 markdown 而不修改它，那么你必须将它放在 Python 库需要的地方，例如 site-packages/ 中。否则，您将必须修改它以使用相对导入而不是绝对导入。

更新 2 我通过修改应用程序引擎中的 sys.path 解决了这个问题：

sys.path.append(os.path.join(os.path.dirname(file), 'lib'))
