    这是一个创建于 2651 天前的主题，其中的信息可能已经有所发展或是发生改变。
    32 位的 WINDOWS7，PYTHON3.6 环境下要安装 Scrapy-1.4.0-py2.py3-none-any.whl ，这个 whl 文件已经下载并放到 python 目录下，输入命令为 pip install Scrapy-1.4.0-py2.py3-none-any.whl
    安装了很多包后，出现了以下的出错提示，请问这是什么原因导致的，如何解决呢？感谢指点！

    我自己似乎是先单独安装 lxml 和 twisted 的 whl，装好以后再安装 scrapy 的 whl 装好的

    @leoforza lxml 我已经安装完毕了，twisted 我是从 https://pypi.python.org/pypi 上找的 Twisted-17.5.0.tar.bz2 ，解压后，用 pip install setup.py 来安装时提示：
    Could not find a version that satisfies the requirement setup.py (from versions: )
    No matching distribution found for setup.py

    难道这个版本不适用于 32 位的 WINDOWS 7 么？ 那这样就找不到其他版本了，我是 INTEL 的芯片。

    @saximi 要不还是在 http://www.lfd.uci.edu/~gohlke/pythonlibs/ 这个网页上找 whl 安装吧，tar.bz2 压缩包安装我也经常出问题
