Ubuntu pip 安装网络爬虫框架 scrapy 出现的错误

1.问题

 

 

  File "/usr/bin/pip", line 9, in <module>
    load_entry_point('pip==1.5.4', 'console_scripts', 'pip')()
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 351, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2363, in load_entry_point
    return ep.load()
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2088, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
  File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 11, in <module>
    from pip.vcs import git, mercurial, subversion, bazaar  # noqa
  File "/usr/lib/python2.7/dist-packages/pip/vcs/mercurial.py", line 9, in <module>
    from pip.download import path_to_url
  File "/usr/lib/python2.7/dist-packages/pip/download.py", line 25, in <module>

 

按照教程安装，最后仍出现上面错误，最后发现是pip的版本太低，更新时使用的时Ubuntu自带的pip出现上面错误。

 

Ubuntu14.04上你用sudo apt-get install python-pip下载安装，在使用时出现上面的错误

 

于是查看教程，使用下面安装方法

wget https://bootstrap.pypa.io/get-pip.py  --no-check-certificate
sudo python get-pip.py


最后发现安装时还时不能安装。于是试试看卸载原来的pip，在安装发现能安装

apt-get remove --purge python-pip 后在进行安装便可以成功安装pip了，然后 

sudo  pip install Scrapy  后便能成功安装Scrapy
