Emacs flycheck python false postive with print()

您的代码使用语法检查器触发以下警告 python-flake8 3.5.0 )并且没有改变默认行为的配置文件。问题不在于Flycheck,而在于您的代码:

 1   1 warning  F403   'from sys import *' used; unable to detect undefined names (python-flake8)
 2  45 warning  E251   unexpected spaces around keyword / parameter equals (python-flake8)
 2  47 warning  E251   unexpected spaces around keyword / parameter equals (python-flake8)
 2  48 warning  F405   'stderr' may be undefined, or defined from star imports: sys (python-flake8)

M-x flycheck-list-errors 一定会 C-c ! l 默认情况下会显示这个。

以下内容不会产生任何错误:

from sys import stderr

print('this is an error, like you 3:)', file=stderr)
