python - 如何使用Python报库？

Question

我正在尝试制作网络解析器并保存它。我找到了 newspaper图书馆。我正在使用 Eclipse。但是我得不到好结果。请帮助我。

import newspaper

cnn_paper = newspaper.build('http://cnn.com')

for article in cnn_paper.articles:
    print(article.url)

这是一条错误信息:

    import urllib.request
ImportError: No module named request

Answer 1

您的代码没有任何问题。您将需要安装或找到 newspaper 和 request 库。您的开发机器上似乎缺少 newspaper/request 库。

$ pip install newspaper
$ pip install urllib3

上面的命令将帮助您安装它。
