对我来说，以上这些都没用。但是，我解决了安装libssl-dev的问题。

sudo apt-get install libssl-dev

这可能会工作，如果你有相同的错误信息在我的情况下:

致命错误:openssl/openssl .h:没有这样的文件或目录... .... 命令“x86_64-linux-gnu-gcc”退出状态为1失败

$ 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

尝试安装这些包。

sudo apt-get install build-essential autoconf libtool pkg-config python-opengl python-pil python-pyrex python-pyside.qtopengl idle-python2.7 qt4-dev-tools qt4-designer libqtgui4 libqtcore4 libqt4-xml libqt4-test libqt4-script libqt4-network libqt4-dbus python-qt4 python-qt4-gl libgle3 python-dev libssl-dev

sudo easy_install greenlet

sudo easy_install gevent

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

python3:

sudo apt-get install python3-dev \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python3-pip

Python2:

sudo apt-get install python2-dev  \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python2-pip

在我的情况下，听从命令是有魔力的

sudo apt-get install gcc python3-dev

如果上面的命令不起作用，请尝试以下两个命令

sudo apt-get install gcc python-dev

当您希望它在您的机器中为默认python版本安装时，就会出现这种情况。

Or

sudo apt-get install gcc python3.x-dev

python3的地方。X表示安装在您机器上的python的版本号。
