【问题描述】：

Python 声明news 模块未安装：

$ python -c "import news"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named news

即使：

$ pip show news

有什么建议可以让news 被识别吗？

编辑 1，回复@JacobIRR：

news 已安装 - 没有投诉 - 与 pip（见下文），但在 site-packages 中似乎没有 news 子目录。

【问题讨论】：

如果导航到 /usr/lib/python2.7/site-packages 的内部目录，news 目录是否具有与其他工作包相同的权限和统计信息？
见 Edit 1, @JacobIRR.

标签： python python-module

【解决方案1】：

好吧，我从 pypi 下载了模块，看看里面有什么。 news-1.0.zip 只有一个名为news_module.py 的文件，其中有一个方法read_news。

所以，你应该试试

$ python -c "import news_module"

问：您是否正在寻找 newspaper 模块？

【讨论】：

在回答你的问题时，寻求我帮助的人回答了足够多的问题，让我猜想news 实际上是一个 local 模块 (news.py) -他一开始就很方便地忘记了;-)
啊，这就回答了。我们在 Pip 的存储库中寻找它。其中也有一个同名的！
