使用Ubuntu 14.04 LTS和运行python 3.5的virtualenv，我必须做:

sudo apt-get install python3.5-dev

其他命令:

sudo apt-get install python-dev
sudo apt-get install python3-dev

没有帮助。我认为这是因为virtualenv需要依赖于系统范围的python-dev包，它必须匹配virtualenv的python版本。但是，使用上述命令安装python-dev for python 2。X和蟒蛇Ubuntu 14.04是3.4版，不是3.5版。

$ 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

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

对于Python 3.4使用:

sudo apt-get install python3.4-dev

对于Python 3.5，请使用:

sudo apt-get install python3.5-dev

对于Python 3.6使用:

sudo apt-get install python3.6-dev

对于Python 3.7，请使用:

sudo apt-get install python3.7-dev

对于Python 3.8使用:

sudo apt-get install python3.8-dev

．.． 等等……

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

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。
