导入“faker”无法解决（PylancereportMissingImports）

Question

import os
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'first_project.settings')

import django
django.setup()

#FAKE POP SCRIPT
import random
from first_app.models import Topic, AccessRecord, Webpage
from faker import Faker

fakegen = Faker()
topics = ['Search', 'Social', 'Market', 'News', 'Games']

def add_topic():
    t = Topic.objects.get_or_create(top_name = random.choice(topics))[0]
    t.save()
    return t
def populate(N=5):

    for entry in range(N):
        #Get the topic for the entry
        top = add_topic()
    
        #Create the fake data for that entry
        fake_url = fakegen.url()
        fake_date = fakegen.date()
        fake_name = fakegen.company()
    
        #Create the new webpage entry
        webpg = Webpage.objects.get_or_create(topic = top,url = fake_url, name = fake_name)[0]
    
        #Create a fake access record for that webpage
        acc_rec = AccessRecord.objects.get_or_create(name = webpg, date = fake_date)[0]
    
        if __name__ == '__main__':
            print("populating script!")
            populate(20)
            print("populating complete!")

代码执行但不执行任何操作。我已经尝试卸载 faker 并再次安装，安装旧版本，我也尝试使用 pip 和 anaconda 安装，但这些都不起作用。我将不胜感激任何帮助。

Answer 1

if __name__ == '__main__':

的缩进是错误的。正确的方法是在

populate

函数之外，如下所示：

import os
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'first_project.settings')

import django
django.setup()

#FAKE POP SCRIPT
import random
from first_app.models import Topic, AccessRecord, Webpage
from faker import Faker

fakegen = Faker()
topics = ['Search', 'Social', 'Market', 'News', 'Games']

def add_topic():
    t = Topic.objects.get_or_create(top_name = random.choice(topics))[0]
    t.save()
    return t
def populate(N=5):

    for entry in range(N):
        #Get the topic for the entry
        top = add_topic()
    
        #Create the fake data for that entry
        fake_url = fakegen.url()
        fake_date = fakegen.date()
        fake_name = fakegen.company()
    
        #Create the new webpage entry
        webpg = Webpage.objects.get_or_create(topic = top,url = fake_url, name = fake_name)[0]
    
        #Create a fake access record for that webpage
        acc_rec = AccessRecord.objects.get_or_create(name = webpg, date = fake_date)[0]
    
if __name__ == '__main__':
    print("populating script!")
    populate(20)
    print("populating complete!")

使用 最小可重现示例进行测试，它有效：

from faker import Faker

fakegen = Faker()

def populate(N=5):
    for _ in range(N):
        #Create the fake data for that entry
        fake_url = fakegen.url()
        fake_date = fakegen.date()
        fake_name = fakegen.company()
        print(fake_url, fake_date, fake_name)

if __name__ == '__main__':
    print("populating script!")
    populate(20)
    print("populating complete!")

输出

populating script!

Answer 2

导入可能不可见，因为您使用了错误的Python解释器

第 1 步：选择正确的 Python 解释器

1. 打开命令面板：按

   Ctrl+Shift+P

   （或 Mac 上的

   Cmd+Shift+P

   ）在 VSCode 中打开命令面板。
2. 搜索“Python：选择解释器”：在命令面板中键入此命令。
3. 选择解释器：查找与您的虚拟环境相对应的解释器路径（在您的情况下为

   app--vubfewl

   ）。它应该看起来像

   C:\Users\jefde\.virtualenvs\app--vubfewl\Scripts\python.exe

   。
4. 选择它：单击此解释器将其设置为 VSCode 会话的活动 Python 解释器。

第2步：重新加载或重新启动VSCode

有时 VSCode 需要重新加载才能正确识别 Python 环境中的更改：

• 重新加载窗口：使用

  Ctrl+Shift+P

  再次打开命令面板，输入“重新加载窗口”并选择它以刷新 VSCode 环境。
