在同样的情况下，请考虑其中一个安装文件中的错字(错误)，并手动编辑它，将“X509_REVOKED_dup”更改为“X509_REVOKED_dupe”(没有引号)。我已经编辑了x509.h文件:

sed -e的 usr / include / openssl - x509。h

这对我来说很有效，但请参考下面链接的帖子，因为他们编辑了另一个文件:

sed -e's/X509_REVOKED_dup/X509_REVOKED_dupe/g' -i OpenSSL/crypto/crl.c . sed -e's/X509_REVOKED_dup/X509_REVOKED_dupe/g

首先你需要找出实际的问题是什么。你看到的是C编译器失败了，但你还不知道为什么。向上滚动到得到原始错误的地方。在我的情况下，尝试使用pip3安装一些包，我发现:

    Complete output from command /usr/bin/python3 -c "import setuptools, tokenize;__file__='/tmp/pip-build-4u59c_8b/cryptography/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-itjeh3va-record/install-record.txt --single-version-externally-managed --compile --user:
    c/_cffi_backend.c:15:17: fatal error: ffi.h: No such file or directory

 #include <ffi.h>

                 ^

compilation terminated.

所以在我的情况下，我需要安装libffi-dev。

这个问题可能源于任何一个缺失的包，尤其是在更新的版本中。

大多数人都用最后一行搜索。

错误:command '/usr/bin/x86_64-linux-gnu-gcc' failed with exit code 1

但如果你仔细看，上面的几行，你可以看到哪个包丢失了。它清楚地指出一个目录或文件丢失了

gssapi/gssapi.h:没有这样的文件或目录

搜索为什么这个包可能是你正在寻找的解决方案。

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

今天用pip升级了我的电脑，并检查了这里的其他答案，我可以告诉你它可能是任何东西。您应该逐一检查错误，查找您需要的特定库。在我的例子中，这些是我必须安装的库:

$ sudo apt-get install libssl-dev
$ sudo apt-get install libffi-dev
$ sudo apt-get install libjpeg-dev
$ sudo apt-get install libvirt-dev
$ sudo apt-get install libsqlite3-dev
$ sudo apt-get install libcurl4-openssl-dev
$ sudo apt-get install libxml2-dev libxslt1-dev python-dev

在ubuntu 14.04中:

sudo apt-file search ffi.h 

返回:

pypy-doc: /usr/share/doc/pypy-doc/html/rffi.html

我选择安装libffi-dev

sudo apt-get install libffi-dev

完美的工作
