在python virtualenv中安装scrapy使用pip时出错

系统信息：

Ubuntu 14.10
Linux vagrant-ubuntu-trusty 3.16.0-23-generic #31-Ubuntu SMP Tue Oct 21 17:56:17 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

我首先在ubuntu中安装了

virtualenv

sudo pip install virtualenv
virtualenv scrapy-env
cd scrapy-env/
source bin/activate
pip install scrapy

然后我得到这个错误：

有什么建议可以帮我修复吗？

您没有安装Python开发包。尝试安装它们

sudo apt-get install python-dev # for python2.x installs
sudo apt-get install python3-dev  # for python3.x installs

请仔细阅读！运行

sudo apt get install python dev

后可能会重复此错误：

以下软件包具有未满足的依赖关系：python dev:Depends:python（=2.7.5-5ubuntu3），但要安装的2.7.8-1依赖于：libpython dev（=2.7.5-5ubuntu3）但它不会被安装，具体取决于：python2.7-dev（>=2.7.5-1~），但它不会被安装。E：无法纠正问题，您持有损坏的软件包。

请先尝试更新python
