Question

我正在尝试在python上安装报纸模块，但是我不断收到错误消息，说没有这样的模块。

我已尝试确保将目录设置在正确的位置，并且已检查模块是否已安装。我正在使用的PyCharm会在我检查时显示它已安装。为什么当我明确已经安装了模块时却说没有模块？

Answer 1

它可以作为newspaper导入：

import newspaper

（PyPI名称并不总是与包名称对齐。）

>>> import newspaper
>>> newspaper.__version__
'0.2.7'

从shell：

$ pip list | grep newspaper
newspaper3k              0.2.7

更具体地说，newspaper3k中定义了名称setup.py。不一定必须在文件级别匹配顶级程序包名称。

ModuleNotFoundError：没有名为“ newspaper3k”的模块
