Python模塊scrapy總是會產生Traceback錯誤

Question

我在scrapy（ http://scrapy.org/ ）上遇到了一些問題，實際上它不起作用。 我使用安裝

pip install scrapy

在安裝了python 3.4.3的Windows系統（帶有Anaconda3）上，一切正常。 是Scrapy-1.0.5。

然后，我嘗試做本教程，但是第一個命令已經失敗了：

scrapy startproject tutorial

給出以下錯誤：

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:

關於這里有什么問題或如何解決的任何想法？

我嘗試卸載並重新安裝scrapy，沒有任何變化。 還嘗試使用更新

pip install -U scrapy

失敗並顯示錯誤消息

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 

實際上，我不知道這里出了什么問題。 看起來python解析器模塊在這里不起作用。

不帶任何參數調用Scrapy會給出相同的錯誤消息。

Answer 1

好吧，我剛剛調查了這個問題：Scrapy不支持Python 3.4。，僅支持Python 2.7。

我可以刪除這篇文章，但將來也許其他人會像我以前一樣愚蠢，這可能會有所幫助。

謝謝，抱歉。
