Cannot import urllib in Python
提问by Square9627
I would like to import urllibto use the function 'request'. However, I encountered an error when trying to download via Pycharm:
我想导入urllib以使用函数“ request”。但是，我在尝试通过 Pycharm 下载时遇到错误：
"Could not find a version that satisfies the requirement urllib (from versions: ) No matching distribution found for urllib"
“找不到满足 urllib 要求的版本（来自版本：）没有找到与 urllib 匹配的发行版”
I tried pip install urllibbut still had the same error. I am using Python 2.7.11. Really appreciate any help

A few things:
一些东西：
- As metioned in the comments,
urllibis not installed throughpip, it is part of the standard library, so you can just doimport urllibwithout installation. - Python 3.x has a
urllib.requestmodule, but Python 2.x does not, as far as I know. The functionality that you are looking for from
urllib.requestis most likely contained inurllib2(which is also part of the standard library), but you might be even better off usingrequests, which probably does need to be installed throughpipin your case:pip install requestsIn fact, the
urllib2documentation itself recommends that you use therequestslibrary "for a higher-level HTTP client interface" - but I am not sure what you wish to do, so it is hard to say what would be best for your particular use case.
- 正如评论中提到的，
urllib不是通过 安装的pip，它是标准库的一部分，所以你可以import urllib不用安装。 urllib.request据我所知，Python 3.x 有一个模块，但 Python 2.x 没有。您正在寻找的功能
urllib.request很可能包含在urllib2（它也是标准库的一部分）中，但您最好使用requests，pip在您的情况下可能需要安装它：pip install requests事实上，
urllib2文档本身建议您使用该requests库“用于更高级别的 HTTP 客户端接口” - 但我不确定您希望做什么，因此很难说哪种方式最适合您的特定用例。
