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

在安装了许多库之后，对我有用的那一个!大喝:

sudo apt-get install swig

安装python的M2Crypto库时出现错误。

在ubuntu 14.04中:

sudo apt-file search ffi.h 

返回:

我选择安装libffi-dev

sudo apt-get install libffi-dev

完美的工作

$ 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

在我的例子中，命令sudo apt-get install unixodbc-dev解决了这个问题。我得到了一个特定于sql.h头文件的错误。
