py2App在别名模式下工作，而不是在最终分发文件中工作

Question

所以我终于有了一个应用程序在py2app别名模式下工作。我可以打开文件，效果很好。删除构建＆amp; dist文件并运行python setup.py py2app，包收到错误。为什么要这样做？

magnolia.py:

    from splinter import Browser
import webbrowser

with Browser() as browser:
    # Visit URL
    url = "http://magnolia.msstate.edu/k12/login.asp"
    browser.visit(url)
    browser.fill('username', 'magn0897')
    # Find and click the 'search' button
    button = browser.find_by_name('btnG')
    # Interact with elements
    browser.find_by_xpath('//html/body/div[3]/div[1]/div/section/form/input').click()
#Open browser in new tab to keep browser open
webbrowser.open_new_tab('http://magnolia.msstate.edu/k12/elementary.asp')

setup.py：

from setuptools import setup

APP = ['magnolia.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True,'iconfile': 'robot.icns'}

setup(
    app=APP,
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
)

在终端打开magnolia.app之后：
