与请求模块FLASK导入错误

Question

前言

您好所有我收到的时候我试图使用python的烧瓶模块一个非常奇怪的错误。首先让我解释，我第一次开始写程序，然后它停止工作没有问题我的最后一个副本应该工作......对吗？在我尝试恢复到当前版本代码之前的2个版本之后，我仍然得到相同的错误，我已经完成了我现在所能做的一切，现在是时候将其提供给专业人员

好吧，发生了什么事是，当我尝试运行我的烧瓶应用

 Traceback (most recent call last): 
    File "/Users/me/Desktop/ASL server/router.py", line 47, in <module> 
     from flask import * 
    File "/Library/Python/2.7/site-packages/flask/__init__.py", line 17, in <module>

     from urllib.request import parse_http_list as _parse_list_header 
    ImportError: No module named request 

目前我试图卸载模块，并与所有支持模块重新安装它一起。该代码是从错误发生之前恢复的代码，现在错误再次发生（旧代码没有更改）我不知道什么问题是...

我的python代码是

Answer 1

其实2个语句是做几乎相同：

from flask import * 
import flask 

当您尝试使用在瓶中的方法，你有2种选择： 1：

from flask import * 
c = request.remote_addr 

第二：

import flask 
c = flask.request.remote_addr 

你使用import a_module注意到不同的使用from a_module import *，你可以使用该方法在module.When名称，就可以给你使用的模块的编译器，如？ ：a_module.method_name

Answer 2

有时目录中断...尝试将文件复制出目录并创建一个新目录，然后重新运行应该工作的服务器。

我想通了，因为它工作之前，然后再次工作。你的代码很好！
