包setup.py和燒瓶目錄結構

Question

更新：添加了setup.py內容。

我有以下目錄結構：

setup.py 
packagename/ 
    __init__.py 
    useless_file.py 

在__init__.py，我有以下幾點：

from flask import Flask 
from flask.ext.sqlalchemy import SQLAlchemy 

db = SQLAlchemy() 

CONFIG_FILENAME = "packagename.settings" 


def create_app(): 
    app = Flask(__name__) 
    app.config.from_object(CONFIG_FILENAME) 

    db.init_app(app) 

    app.register_blueprint(sms_testing) 

    return app 

我跟着瓶的recommended package structure。

這裏是setup.py：

import os 
from setuptools import setup 

requires = (
     "flask", 
     "flask-sqlalchemy", 
     "requests>=0.13.6", 
     "python-dateutil>=1.5", 
     "twilio", 
     "selenium", 
     ) 

def read(fname): 
    return open(os.path.join(os.path.dirname(__file__), fname)).read() 

setup(
    name = "Package Name", 
    version = "0.0.1", 
    author = "Charles-Axel Dein", 
    author_email = "ca@d3in.org", 
    description = ("useless"), 
    license = "BSD", 
    keywords = "example documentation tutorial", 
    url = "http://packages.python.org/an_example_pypi_project", 
    packages=['package_name',], 
    # namespace_packages = ['package_name'], 
    install_requires=requires, 
    long_description=read('README.md'), 
    classifiers=[ 
     "Development Status :: 3 - Alpha", 
     "Topic :: Utilities", 
     "License :: OSI Approved :: BSD License", 
    ], 
) 

當我做python setup.py develop，我得到：

Traceback (most recent call last): 
    File "setup.py", line 2, in <module> 
    from setuptools import setup 
    File "/.virtualenvs/api/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg/setuptools/__init__.py", line 2, in <module>

    raise ImportError('No module named %s' % fullname) 
ImportError: No module named flask 

（我絕密的文件夾），我想這是合乎邏輯的

，因爲setuptools的試圖導入我的軟件包，該軟件包在導入packagename/__init__.py之前，有import flask之前有機會安裝它。

事情是，我需要這import flask在__init__.py來創建數據庫。

你會怎麼推薦？

謝謝！

我個人不喜歡python setup.py develop，你試過嗎？

% pip install -e . 

其中當前目錄是其中包含setup.py的目錄。它與develop類似，但會安裝所有必需的軟件包。
