安装scrapy时出错

时间:2015-03-14 08:42:08

标签: python scrapy pip gnu

我只是试着运行一个简单的

sudo pip install scrapy

在下载每个组件后,它给了我一个错误:

Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip-build-s37cTl/cffi/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-62NAJB-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-s37cTl/cffi

我满足所有的家属,不知道可以做什么。 我运行Debian 7。

谢谢!

编辑:我粘贴整个安装终端输出:
