Question

我为Django项目创建了一个virtualenv。在这个项目中，我有一个带有＆＃39; views.py＆＃39;的app文件夹。

我已经在这个virtualenv中安装了漂亮的汤和请求，并且它们正确导入到了views.py＆＃39;。

但是，为了测试puroposes，我在同一个文件夹中创建了另一个脚本，其中包含＆＃39; views.py＆＃39;但是当我尝试导入相同的模块时，我得到了没有命名的模块......＆＃39;错误。

Virtualenv pip冻结看起来像这样：

beautifulsoup4==4.6.0
certifi==2018.1.18
chardet==3.0.4
Django==2.0.3
idna==2.6
pkg-resources==0.0.0
pytz==2018.3
requests==2.18.4
selenium==3.10.0
urllib3==1.22

Views.py：

from django.shortcuts import render
import os
import webbrowser
import requests, bs4
import re
from .forms import RoomForm
from django.shortcuts import render
from django.http import HttpResponseRedirect
#~ #-*- coding: utf-8 -*-

#~ # Create your views here.

def index(request):
    if request.method == 'POST':
        print('PPPPPPOOOOOOOOSSSSSSSTTTTTTT')
        form = RoomForm(request.POST)
        if form.is_valid():
            print('VAAAALLLLLLIIIIIIDDDDDDDD')
            global form_data
            form_data = form.cleaned_data
            return HttpResponseRedirect('results')
    else:
        print('GGGGEEEEEETTTTT')
        form = RoomForm()


    context = {'form': form}
    return render(request, 'javascript/index.html', context)

def results(request):
    print(request.method)
    city = form_data['city'].title()
    print(city)
    prices = []
    real_prices = []
    url = 'https://www.airbnb.pl/s/' + city +'--Hiszpania/homes?refinement_paths%5B%5D=%2Fhomes&query=' + city + '%2C%20Hiszpania&checkout=2018-04-22&children=0&infants=0&adults=2&guests=2&allow_override%5B%5D=&price_max=252&room_types%5B%5D=Entire%20home%2Fapt&min_beds=0&s_tag=Ph6ohhjw'
    webbrowser.open(url)
    response = requests.get(url)
    response_text = response.text
    airbnb_soup = bs4.BeautifulSoup(response_text)
    page_selectors = airbnb_soup.select('._1bdke5s')
    print(len(page_selectors))
    last_page_selector = page_selectors[len(page_selectors) - 1]##############-15
    last_page_selector = last_page_selector.getText()
    for x in range(0, int(last_page_selector)):
        response = requests.get(url + '&section_offset=' + str(x))
        response_text = response.text
        airbnb_soup = bs4.BeautifulSoup(response_text)
        spans = airbnb_soup.select('._hylizj6 span')
        for i in range(0, len(spans)):
            prices.append(spans[i].getText())
        for price in prices:
            if 'zł' in price:
                real_prices.append(price)
    real_prices.sort()
    print(real_prices)
    #print(real_prices)
    context = {'response_text': response_text, 'airbnb_soup': airbnb_soup,'spans': spans, 'real_prices': real_prices}
    return render(request, 'javascript/results.html',context)

如何正确导入这些模块？

编辑：我在我的观看次数中评论了所有内容。除了import bs4, requests，我得到了同样的错误。但是，当我的应用程序在开发服务器上运行时，它们都能正常工作。

将要求保存到文件：

pip freeze > requirements.txt

激活virtualenv：

source /path/to/env/bin/activate

安装包：

pip install -r requirements.txt

在要导入的.py文件中，使用：

from . import beautifulsoup
