在python virtualenv中使用pip安装scrapy时发生错误

Question

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virtualenv

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

然后我收到这个错误：

    ----------------------------------------
Command "/vagrant/pyenv/scrapy-env/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-NJKTtN/Twisted/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-_i2ueH-record/install-record.txt --single-version-externally-managed --compile --install-headers /vagrant/pyenv/scrapy-env/include/site/python2.7/Twisted" failed with error code 1 in /tmp/pip-build-NJKTtN/Twisted/

有什么建议可以帮我解决吗？
