Python 模块 scrapy 总是给出回溯错误

Question

我在使用 scrapy (http://scrapy.org/) 时遇到了一些问题，实际上它不起作用。我使用

安装它

pip install scrapy

在安装了 python 3.4.3（使用 Anaconda3）的 Windows 系统上，一切正常。这是Scrapy-1.0.5.

然后我试着做教程，但是第一个命令已经失败了：

scrapy startproject tutorial

给出以下错误：

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:

关于这里出了什么问题或如何解决它有什么想法吗？

我尝试卸载并重新安装 scrapy，没有任何改变。还尝试使用

更新它

pip install -U scrapy

失败并显示错误消息

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

实际上，我不知道这里有什么问题。看起来 python 解析器模块在这里不起作用。

不带任何参数调用 Scrapy 会给出相同的错误消息。

Answer 1

好吧，我刚刚调查了这个问题： Scrapy 不支持 Python 3.4.，只支持 Python 2.7.

我可以删除这个 post 但也许将来会有其他人像我一样愚蠢，这可能会有所帮助。

谢谢，抱歉。
