python - 如何在linux机器上安装Scrapy

Question

我已经在我的机器上安装了 python2.7。然后我尝试使用以下命令安装 scrapy，但它抛出了一些异常。

root@boss[elcot]#pip install scrapy
Requirement already satisfied (use --upgrade to upgrade): scrapy in /usr/local/lib/python2.7/site-packages/Scrapy-0.22.0-py2.7.egg
Downloading/unpacking Twisted>=10.0.0 (from scrapy)
  Downloading Twisted-13.2.0.tar.bz2 (2.7MB): 2.7MB downloaded
Cleaning up...

Storing debug log for failure in /root/.pip/pip.log

如何解决这个问题......

也许你需要在你的python2.7安装中安装pip:

wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
python2.7 get-pip.py

如果你最终有多个 pip 命令，你可以像这样从 python2.7 调用一个

python2.7 -m pip install scrapy
