在ubuntu 14.04中:

sudo apt-file search ffi.h

我选择安装libffi-dev

sudo apt-get install libffi-dev

完美的工作

尽管这是一个老问题，我还是要补充一下我的观点。

我认为正确的答案取决于gcc编译器的错误消息，比如“Missing xxxx.h”

这在某些情况下可能会有所帮助:

sudo apt-get install build-essential python-dev

$ sudo apt-get install gcc
$ sudo apt-get install python-dateutil python-docutils python-feedparser python-gdata python-jinja2 python-ldap python-libxslt1 python-lxml python-mako python-mock python-openid python-psycopg2 python-psutil python-pybabel python-pychart python-pydot python-pyparsing python-reportlab python-simplejson python-tz python-unittest2 python-vatnumber python-vobject python-webdav python-werkzeug python-xlwt python-yaml python-zsi

或者试试这个:

$ sudo apt-get install libxml2-dev libxslt1-dev

这招对我很管用:

安装zlib1g-dev

您需要安装这些软件包:

sudo apt-get install libpq-dev python-dev libxml2-dev libxslt1-dev libldap2-dev libsasl2-dev libffi-dev libjpeg-dev zlib1g-dev

对我来说，我必须确保我使用了正确版本的密码学。 pip.freeze有一个较旧的版本，一旦我使用了最新的问题，就会消失。
