Question

我正在尝试安装一个名为news-please的Python包。此软件包已在PyPi和Github上。

当我按照Github页面上显示的pip install news-please时，它会显示以下内容：

No matching distribution found for lxml>=3.35 (from news-please)
You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' 
command.

现在问题在于它无法找到满足要求的版本lxml＆gt; = 3.35。

我已经有一个大于3.35的lxml版本。当我做'pip show lxml＆＃39;时，它告诉我我当前的版本是3.8.0。

如何解决此问题？

Answer 1

如果您已经满意these dependencies：

pywin32 >=220 ; sys_platform == 'win32'
lxml >=3.35 ; sys_platform == 'win32'
Scrapy>=1.1.0
PyMySQL>=0.7.9
hjson>=1.5.8
elasticsearch>=2.4
beautifulsoup4>=4.3.2
readability-lxml>=0.6.2
newspaper3k>=0.1.7 ; python_version >= '3.0'
newspaper>=0.0.9.8 ; python_version == '2.7'
langdetect>=1.0.7
python-dateutil>=2.4.0
plac>=0.9.6
future>=0.16.0 ; python_version == '2.7'
PyDispatcher>=2.0.5
dotmap>=1.2.17
warcio>=1.3.3
ago>=0.0.9

然后你可以使用

pip install --no-deps -U news-please

要有pip安装新闻 - 请不要依赖。

有关如何在Windows上安装新闻娱乐的信息，可在文档中找到，例如https://github.com/fhamborg/news-please/wiki/user-guide#windows-systems

因此，您需要安装lxml和pywin32：

lxml:

Go to Christoph's Gohlke's Python page and download the compatible wheel for your system.
(32bit : "lxml-X.X.X-cp35-cp35m-win32.whl"; 64bit: "lxml-X.X.X-cp35-cp35m-win_amd64.whl")

Open the Windows console and navigate to your Python installation:

 C:\Users\USERNAME>cd  C:\Python35  
Install the wheel with the following command:

 C:\Python35> pip install lxml-X.X.X-cp35-cp35m-win32.whl  
pywin32:

Download the latest build of pywin32.
Make sure you select correct version (matches Python version, 32bit/64bit)

Execute the installer

找不到满足要求的版本lxml新闻 - 请
