python - Flake8 报告 E999 SyntaxError atom Flake 8

Question

我无法解决 flake8 SyntaxError，尽管代码执行得很好。

没有注释的代码

import math


def answer(str_n):
    sume = ((str_n * (str_n + 1)) / 2) * math.sqrt(2)
    sume = int(sume)
    return sume


def answer1(str_n):
    sume = 0
    for i in range(str_n + 1):
        sume += math.floor(i * math.sqrt(2))
        # print i,math.floor(i*math.sqrt(2))
    return sume


print "Test answer:", answer(77)
print "Actual answer:", answer1(77)

Answer 1

Flake8 启动器将 Python3 硬编码为主要 Python。

怎么修:

1) 使用 pip 安装 flake8 包
$ pip install flake8
pip 会告诉您 flake8 脚本尚未添加到路径并打印路径(在我的情况下为 /Library/Frameworks/Python.framework/Versions/2.7/bin/)

2) 调整您的 IDE (Atom/PyCharm/etc) 以将此脚本与您的默认 Python 2.7 一起使用(我的示例来自 PyCharm @ MacOS):

PyCharm -> Preferences -> External tools -> "flake8 - current file"
Program: /usr/local/bin/python 
Arguments: /Library/Frameworks/Python.framework/Versions/2.7/bin/flake8 --ignore=E501,E124,E127,E128 $FilePath$
Working directory: $FileDir$

[x] open console for tool output 
Output filters: $FILE_PATH$\:$LINE$\:.*

它将正常工作而不报告 E999.ha
