防止在ipython shell中显示调试日志信息

Question

我在virtualenv中使用了刮板外壳。IPython安装在virtualenv内部。当我开始使用scrapy shell时

 scrapy shell 'https://example.com'

并按Tab键获取自动完成建议，它会显示很多调试信息。如何禁用此功能？

Answer 1

尝试这样做以将日志记录级别设置为WARNING：

import logging

logging.getLogger().setLevel(logging.WARNING);

任何级别INFO或DEBUG不应该再出现的日志消息。您还可以将日志级别设置为logging.ERROR. 然后WARNING消息也不会出现。

祝你好运！

https://github.com/ipython/ipython/issues/10946看起来像这里报告的错误。

如果您需要在ipython中进行调试日志记录，请尝试 logging.getLogger('parso.cache').disabled=True logging.getLogger('parso.cache.pickle').disabled=True

并等待parso更新

您可以使用-L命令行选项将日志级别更改为INFO：

scrapy shell -L INFO https://example.com
