Python模块scrapy总是会产生Traceback错误

Question

I have some problems with scrapy ( http://scrapy.org/ ), actually it doesn't work. I installed it using

pip install scrapy

on a Windows System with python 3.4.3 installed (with Anaconda3), everything worked fine. It's Scrapy-1.0.5.

Then I tried to do the tutorial, but already the first command failed:

scrapy startproject tutorial

gives the following Error:

Traceback (most recent call last):
  File "C:\Anaconda3\lib\site-packages\setuptools-17.1.1-py3.4.egg\pkg_resources\__init__.py", line 651, in _build_master

During handling of the above exception, another exception occurred:

Any ideas about whats wrong here or how to fix it?

I tried out to uninstall and reinstall scrapy, nothing changed. Also tried to update it using

pip install -U scrapy

which failes with the error message

Command "C:\Anaconda3\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\meyer\\AppData\\Local\\Temp\\pip-build-5zv6_xhq\\lxml\\setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record C:\Users\meyer\AppData\Local\Temp\pip-mfxl3hbe-record\install-record.txt --single-version-externally-managed --compile" failed with error code 1 in C:\Users\meyer\AppData\Local\Temp\pip-build-5zv6_xhq\lxml 

Actually, I have no idea whats the problem here. It looks like the python parser modules doesnt work here.

Calling Scrapy without any arguments gives the same error message.

Answer 1

Well I just investigated the problem: Scrapy doesn't support Python 3.4., only Python 2.7.

I could delete this post but maybe someone else in the future will be as dumb as I was and this may help then.

Thanks and sorry.
