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

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

下面的答案对我有用，你可以试试:

sudo apt-get install python3-lxml

这对我来说已经足够了:

sudo apt-get install build-essential

我的堆栈是这样的:

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

我在大学最后一年的主要项目中安装Linux Mint时遇到了同样的问题，下面的第三个解决方案对我有用。

当遇到这个错误时，请在错误之前注意，它可能会说你缺少一个包或头文件-你应该找到它们并安装它们，并验证它是否工作(例如ssl→libssl)。

对于Python 2。x使用:

sudo apt-get install python-dev

对于Python 2.7，请使用:

sudo apt-get install libffi-dev

对于Python 3。x使用:

sudo apt-get install python3-dev

或对于特定版本的Python 3，将x替换为中的次要版本

sudo apt-get install python3.x-dev
