Pylint报告没有导入的文件循环导入

Question

所以Pylint(1.4.3)报告循环导入,它没有多大意义.首先,报告的文件没有import语句.

其次没有文件导入参考文件.__init__.py文件从development_config(有问题的文件)加载配置值,但没有文件导入该文件.

那么为什么Pylint会给我这个警告呢？

我相信这是目前pylint中的一个错误.需要对多个模块进行分析的事情(例如cyclic-import和duplicate-code检测)会被作为重构抛入最后解析的模块文件中.对我来说,这最终成为一个空__init__.py文件,其中有两个都掉进了它.

这两个重构消息都包含有问题的实际模块名称:

• 对于循环导入,有问题的模块列在括号中
• 对于重复代码,有问题的模块列在以下行中 ==

这些的分组不仅限于模块的打印输出,它还会影响摘要报告% errors / warnings by module,其中最终解析的文件获取重构的计数,而实际关注的模块都不会从中获取任何计数.
