问题描述

我遇到了模块 urllib (Python 3.6) 的问题.每次我使用这个模块时，我都会得到一个页面的错误.

I'm running into trouble with the module urllib (Python 3.6). Every time I use the module, I get a page's worth of errors.

urllib 有什么问题以及如何修复它?

what's wrong with urllib and how to fix it?

import urllib.request
url='https://www.goodreads.com/quotes/tag/artificial-intelligence'
u1 = urllib.request.urlopen(url)
print(u1)

那段代码喜欢吐出这口东西:

That block of code likes to spit out this mouthful of stuff:

  Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/urllib/request.py", line 1318, in do_open
    encode_chunked=req.has_header('Transfer-encoding'))

During handling of the above exception, another exception occurred:

    raise URLError(err)
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)>

模块本身似乎有问题.

推荐答案

您可以在 MacOsX 上运行命令行程序来安装证书:

There is command line program that you can run on MacOsX that will install the certificates:

sudo /Applications/Python\ 3.6/Install\ Certificates.command

sudo 命令将提示您输入密码以提升您的权限.

The sudo command will prompt for you password to elevate your privileges.
