Wolfram Alpha Python API无法正常工作 [英] Wolfram Alpha Python API not working

问题描述

我在MacOS Sierra 10.12.3上使用Python 3.6.我安装了wolframalpha，并确保我的应用程序ID有效(使用RESTful的URL请求可以正常使用)，但是当尝试从Wolfram自己的文档中运行示例时，仍然出现此错误.

I'm using Python 3.6 on MacOS Sierra 10.12.3. I installed wolframalpha, and made sure my app id is valid (it works fine with URL requests using RESTful), yet I still get this error when I try and run the example from Wolfram's own documentation.

import wolframalpha

client = wolframalpha.Client('xxxxxx-xxxxxxxxxxx')

res = client.query('temperature in Washington, DC on October 3, 2012')

给我这些错误:

During handling of the above exception, another exception occurred:

    raise URLError(err)

有什么想法吗?我不知道该怎么办了.预先感谢.

Any ideas? I have no idea what to do anymore. Thanks in advance.

推荐答案

ssl.SSLError:[SSL:CERTIFICATE_VERIFY_FAILED]证书验证 失败

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

表示您还必须执行import ssl.
