Version: 1.1.119



The libtaxii library is developed on Python 2.7 and tested against both Python 2.6 and 2.7. Besides the Python Standard Library, libtaxii relies on the following Python libraries:

  • lxml - A Pythonic binding for the C libraries libxml2 and libxslt.
  • python-dateutil - A library for parsing datetime information.

Each of these can be installed with pip or by manually downloading packages from PyPI. On Windows, you will probably have the most luck using pre-compiled binaries for lxml. On Ubuntu (12.04 or 14.04), you should make sure the following packages are installed before attempting to compile lxml from source:

  • libxml2-dev
  • libxslt1-dev
  • zlib1g-dev


In libtaxii 1.0.101 and earlier, the M2Crypto library was also required. This dependency was removed as of libtaxii 1.0.102.


Users have encountered errors with versions of libxml2 (a dependency of lxml) prior to version 2.9.1. The default version of libxml2 provided on Ubuntu 12.04 is currently 2.7.8. Users are encouraged to upgrade libxml2 manually if they have any issues. Ubuntu 14.04 provides libxml2 version 2.9.1.

Manual Installation

If you are unable to use pip, you can also install libtaxii with setuptools. If you don’t already have setuptools installed, please install it before continuing.

  1. Download and install the dependencies above. Although setuptools will generally install dependencies automatically, installing the dependencies manually beforehand helps distinguish errors in dependency installation from errors in libtaxii installation. Make sure you check to ensure the versions you install are compatible with the version of libtaxii you plan to install.
  2. Download the desired version of libtaxii from PyPI or the GitHub releases page. The steps below assume you are using the 1.1.119 release.
  3. Extract the downloaded file. This will leave you with a directory named libtaxii-1.1.119.
$ tar -zxf libtaxii-1.1.119.tar.gz
$ ls
libtaxii-1.1.119 libtaxii-1.1.119.tar.gz


$ unzip
$ ls
  1. Run the installation script.
$ cd libtaxii-1.1.119
$ python install
  1. Test the installation.
$ python
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import libtaxii

If you don’t see an ImportError, the installation was successful.
