在 PyCharm 中运行时记录 basicConfig 不创建日志文件? [英] Logging basicConfig not creating log file when I run in PyCharm?

问题描述

当我在终端中运行下面的代码时，它会创建一个日志文件

When I run below code in terminal its create a log file

import logging 
logging.basicConfig(filename='ramexample.log',level=logging.DEBUG)
logging.debug('This message should go to the log file')
logging.info('So should this')
logging.warning('And this, too')

但是当我在 PyCharm 中运行相同的代码(使用不同的 filename='ram.log')时，它不会创建任何日志文件.为什么?

but when I run the same code (with different filename='ram.log') in PyCharm it's not creating any log file. Why?

import logging 
logging.basicConfig(filename='ram.log',level=logging.DEBUG)
logging.debug('This message should go to the log file')
logging.info('So should this')
logging.warning('And this, too')

我需要做什么才能使用 PyCharm 创建日志文件?

What I have to do to create a log file with PyCharm?

推荐答案

我遇到了同样的问题，发现以前在这里提供的答案都不起作用.也许这个问题早在 Ramnath Reddy 就已经解决了，但我在网上的任何地方都找不到正确的答案.

I encountered same issue and found none of the answers previously provided here would work. Maybe this issue had been solved long ago to Ramnath Reddy, but I could not find the correct answer anywhere online.

幸运的是，我通过在 logging.basicConfig() 之前添加以下几行从同事的代码中找到了解决方案.

Luckily, I found a solution from a colleague's code by adding the following lines before logging.basicConfig().

# Remove all handlers associated with the root logger object.
for handler in logging.root.handlers[:]:
    logging.root.removeHandler(handler)

试试看是否对遇到同样问题的人有帮助.

Try and see if it helps for whomever had the same issue.

Python 3.8:新选项 force 可用于在调用 basicConfig() 时自动删除根处理程序.
例如:

Python 3.8: A new option, force, has been made available to automatically remove the root handlers while calling basicConfig().
For example:

logging.basicConfig(filename='ramexample.log', level=logging.DEBUG, force=True)`

参见 logging.basicConfig 参数:

force:如果此关键字参数指定为 true，则在执行其他参数指定的配置之前，将删除并关闭附加到根记录器的任何现有处理程序.

force: If this keyword argument is specified as true, any existing handlers attached to the root logger are removed and closed, before carrying out the configuration as specified by the other arguments.
