Pylint 仅显示警告和错误答案

【问题标题】：Pylint to show only warnings and errorsPylint 仅显示警告和错误

【问题描述】：

我想使用 pylint 检查我的代码，但我只对错误和警告级别感兴趣。有没有办法在命令行或 pylintrc 中做到这一点？

我对过滤给定问题（例如在 MESSAGE CONTROL 中列出所有消息）不感兴趣，我只想让 pylint 忽略所有约定并重构消息。

注意：我认为这不是 Using Pylint to display error and warnings 的重复项

【解决方案1】：

使用-d / --disable 选项关闭“C”和“R”消息类（约定和重构）：

-d <msg ids>, --disable=<msg ids>
                    Disable the message, report, category or checker with
                    the given id(s). You can either give multiple
                    identifiers separated by comma (,) or put this option
                    multiple times (only on the command line, not in the
                    configuration file where it should appear only
                    once).You can also use "--disable=all" to disable
                    everything first and then reenable specific checks.
                    For example, if you want to run only the similarities
                    checker, you can use "--disable=all
                    --enable=similarities". If you want to run only the
                    classes checker, but have no Warning level messages
                    displayed, use"--disable=all --enable=classes
                    --disable=W"

没有disable 选项（6 个约定，1 个重构，2 个警告，1 个错误）：

$ pylint x.py
C:  1, 0: Missing module docstring (missing-docstring)
C:  3, 0: Missing function docstring (missing-docstring)
R:  3, 0: Too many statements (775/50) (too-many-statements)
W:780,15: Redefining name 'path' from outer scope (line 796) (redefined-outer-name)
C:780, 0: Invalid function name "getSection" (invalid-name)
C:780, 0: Empty function docstring (empty-docstring)
C:782,23: Invalid variable name "inPath" (invalid-name)
W:785, 4: Statement seems to have no effect (pointless-statement)
E:785, 4: Undefined variable 'something' (undefined-variable)
C:796, 4: Invalid constant name "path" (invalid-name)

使用disable 选项后（0 个约定，0 个重构，2 个警告，1 个错误）：

$ pylint --disable=R,C x.py
W:780,15: Redefining name 'path' from outer scope (line 796) (redefined-outer-name)
W:785, 4: Statement seems to have no effect (pointless-statement)
E:785, 4: Undefined variable 'something' (undefined-variable)

在pylintrc中设置这个选项：

disable=R,C

【解决方案2】：

> python -m pylint --errors-only script_to_validate.py

No config file found, using default configuration
************* Module script_to_validate
E:  7,10: Module 'cv2' has no 'imread' member (no-member)
E:  8,15: Module 'cv2' has no 'threshold' member (no-member)

这是使用 Python v3.8 和 Pylint v2.11.1 测试的。
