使用 Pydev 的 python 日志记录时出错

Question

我正在使用来自 Aptana 安装的 PyDev 和 Python 3.5。一切都工作正常，直到我决定探索我以前从未使用过的日志模块。我从教程中的新脚本开始：

import logging
logging.warning('Watch out!')  # will print a message to the console
logging.info('I told you so')  # will not print anything

在 Pydev 我有这个错误：

Traceback (most recent call last):
  File     "C:\Users\Tomasz\workspace\basicLogging.py", line 7, in <module>
    logging.warning('Watch out!')  # will print a message to the console
AttributeError: module 'logging' has no attribute 'warning'

我搜索并发现了以下问题：python : installlogging module有类似的问题但没有解决方案。显然问题不在于安装。当我从 CMD 运行完全相同的脚本时，我有正确的输出。目前，Pydev 似乎给我的大多数脚本都带来了错误。如果我回到之前运行良好的代码，现在我有这个：

Traceback (most recent call last):
  File "C:\Users\Tomasz\workspace\piClientFullQt.py", line 15, in <module>
    from matplotlib.backends import qt_compat

    class _CapturingHandler(logging.Handler):
AttributeError: module 'logging' has no attribute 'Handler'

我不知道这是怎么发生的。如果我print(sys.executable)这样做，在两种情况下都会给出相同的路径C:\Users\Tomasz\AppData\Local\Programs\Python\Python35-32\python3.exe，CMD 运行良好，而 Pydev 给出错误。

我认为 Pydev 中的一些 python 变量有一些问题（我认为），但找不到如何修复它。

编辑： 我看看这个问题并尝试了答案

python解释器的位置是正确的，看起来我有我需要的所有库

C:\Users\Tomasz>python3 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())"
C:\Users\Tomasz\AppData\Local\Programs\Python\Python35-32\Lib\site-packages

并且站点包已经在系统 PYHONPATH 中

我尝试在 Window -> Preferences -> PyDev -> Iterpreters -> Python Interpreter 中恢复默认值

编辑： 按照@Samuel的建议我尝试：

import logging

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

logging.warning('Watch out!')  # will print a message to the console
logging.info('I told you so')  # will not print anything

在 PyDev 中我有：

Traceback (most recent call last):
  File "C:\Users\Tomasz\workspace\SCT2python\goodExamps\logging\basicLogging.py", line 3, in <module>
    logger = logging.getLogger()
AttributeError: module 'logging' has no attribute 'getLogger'

如果我在命令行中作为脚本运行它，它就可以正常工作！

编辑：解决方案 感谢@Samuel，我发现我犯了绝对愚蠢的错误！在我开始使用这个库之前，我创建了一个文件夹来保存我的脚本，我愚蠢地将其称为“日志记录”。显然重命名文件夹解决了问题！

您需要初始化记录器实例：

import logging

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

logger.warning('Watch out!') 
logger.info('I told you so')
