我最近尝试为Python3安装Flake8，此后，我收到以下错误消息：

/Users/dorsam/.atom/packages/linter/lib/linter-registry.js:159 [Linter] Error running Flake8 Error: /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pycodestyle.py:113: FutureWarning: Possible nested set at position 1

看这里： https: //docs.python.org/3/library/re.html

将来可能会添加对 Unicode 技术标准 #18 中的嵌套集合和集合操作的支持。这将改变语法，因此为了促进这一改变，暂时将在不明确的情况下引发 FutureWarning。这包括以文字“[”开头或包含文字字符序列“--”、“&&”、“~~”和“||”的集合。为了避免警告，请使用反斜杠转义它们。
