安裝我的Python 3軟件包問題

Question

最近放了一個小項目來熟悉Python。在進行項目分配的過程中，我創建了以下setup.py：

# -*- coding: utf-8 -*- 


import re 
from setuptools import setup 


setup(
    name = 'bfi', 
    packages = ['bfi'], 
    entry_points = { 
     'console_scripts' : ['bfi = bfi.bfi:main'] 
    }, 
    version = '1.0', 
    description = 'Brainf*ck Interpreter w/Shell-Mode', 
    author = 'Kyle Martinez', 
    install_requires = ['getch', 'overloading'] 
) 

然後我嘗試從命令行安裝包，像這樣：

python3 setup.py install 

這似乎是工作！運行命令給我下面的輸出：

running install

running egg_info 
writing requirements to bfi.egg-info/requires.txt 
writing top-level names to bfi.egg-info/top_level.txt

    print('➲ ', end='')

我有點新所有這一切，所以我會很感激我能得到的任何幫助！我該如何解決這個問題？

注意：正如您可能已經推斷的，我的Macbook安裝了多個Python版本。

看起來你也安裝使用python2.7「BYI」包可能使用python setup.py install

當您運行控制檯腳本BYI，墊片腳本可能指向Python 2.7版。您可以通過查看生成的填充腳本的第一行來確認： head -1 /usr/local/bin/byi

您可以嘗試刪除腳本/usr/local/bin/byi並使用python3重新運行安裝程序。這應該會在源代碼中生成一個新的shim腳本。您還可以通過添加附加選項來控制使用哪個python： options = { 'build_scripts': { 'executable': '/usr/bin/env python3', }, } setup.py

此外，它看起來像您的軟件包與python 2.7不兼容。錯誤的行將在python 2.7上失敗，因爲舊版本除了一個元組而不是函數參數： print '➲ ',而不是print('➲ ', end='')。

如果你想要的Python 2.x的支持，您可以安裝six module
