无法安装Scrapy/Twisted [英] Can't instal Scrapy/Twisted

问题描述

当我使用"pip install"在Windows上为Python安装scrapy时，我请求以下反馈:

When I use "pip install" to install scrapy for Python on Windows, I request this feedback:

Exception:
Traceback (most recent call last):
  File "c:\users\limin\appdata\local\programs\python\python36\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
    return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb6 in position 30: invalid start byte

During handling of the above exception, another exception occurred:

  File "c:\users\limin\appdata\local\programs\python\python36\lib\site-packages\pip\basecommand.py", line 215, in main

    return s.decode('utf_8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb6 in position 30: invalid start byte

我知道这可能是编码问题，但我不知道如何解决. 谁能帮我? 谢谢.

I know it maybe a coding problem, but I don't know how to solve it. Who can help me? Thanks.

推荐答案

Scrapy在Python 2.7和Python 3.3或更高版本上运行(在Windows上尚不支持Python 3除外).

Scrapy runs on Python 2.7 and Python 3.3 or above (except on Windows where Python 3 is not supported yet).

很抱歉成为坏消息的承担者.如果您特别想使用Python 3.6，那么使用Anaconda是值得的，这在Scrapy文档中也有说明.或者，如果很紧急，则可以使用Python 2.7和pip install scrapy.根据我的经验，在Scrapy中使用Python 2.7会更好.

Sorry to be the bearer of bad news. It's worth a chance to use Anaconda, which is also stated in the Scrapy docs, if you're particularly hell bent on using Python 3.6. Or if it's urgent, you can use Python 2.7 and pip install scrapy. From my experience, Python 2.7 works a lot better when in comes to Scrapy.
