Installation Instructions

All supported versions of Python include the Python package management tool pip, which allows an easy installation from the command line on all platforms. Try:

pip install biopython

For updating an older version of Biopython try:

pip install biopython --upgrade

This will remove older versions of Biopython and NumPy before it installs the recent versions.

Should you wish to uninstall Biopython:

pip uninstall biopython

If pip is not already installed you may need to update your Python, but first try:

python -m ensurepip

If you need to install under a specific version of Python, try something like this:

python3.13 -m pip install biopython
pypy -m pip install biopython

On Windows, by default python and pip are not on the PATH. You can re-install Python and tick this option, or give the full path instead. Try something like this, depending on where your copy of Python is installed:

C:\Python39\Scripts\pip install biopython

Other packages

While we generally recommend using pip to install Biopython using the wheel packages we provide on PyPI (as above), there are also Biopython packages for Conda, Linux, etc.

Installation from Source

Installation from source requires an appropriate C compiler, for example GCC on Linux, and MSVC on Windows. For macOS, if you want to compile Biopython from source you will need to have installed Apple’s command line tools, which can de done with the terminal command:

xcode-select --install

This will offer to install Apple’s XCode development suite - you can, but it is not needed and takes a lot of disk space.

You can then download and unzip a Biopython source code release, or get our code from GitHub. Then run:

python setup.py build
python setup.py test
python setup.py install

or:

pip install .

If you are still stuck, sign up to the Biopython mailing list and ask for help there.

Required Software

• Python 3 or PyPy (a version supported by the version of Biopython you wish to install), including the Python development header files like python.h (if compiling from source)
• C compiler (if compiling from source) You need a C compiler supported by setuptools, gcc will work fine on UNIX-like platforms. Try MSVC on Windows. On macOS, you should install Apple’s the compiler tools as described above.
• NumPy (Numerical Python).

Optional Software

Some parts of Biopython use the following additional python libraries:

• ReportLab – used for pdf graphics code
• psycopg – used for BioSQL with a PostgreSQL database
• mysql-connector – used for BioSQL with a MySQL database
• MySQLdb – An alternative MySQL library used by BioSQL

In addition Biopython includes wrapper code for calling a number of third party command line tools including:

• Wise2 – for command line tool dnal
• NCBI Standalone BLAST – command line tool for running BLAST on your local machine
• Clustalw – command line tool for building sequence alignments
• SIMCOAL2 and FDist – command line tools for population genetics
• EMBOSS – lots of useful command line tools.

Old Releases

Recent releases of Biopython require NumPy (and not Numeric). Version 1.76 is the last release to support Python 2.7 and 3.5, all later releases require Python 3:

Please note that Biopython 1.48 and older require the Numeric library, not its replacement NumPy. Windows installers for Python 2.4 and older are available from the Numerical Python website. A Windows installer for Numeric 24.2 for Python 2.5 is available here:

• Numeric-24.2.win32-py2.5.exe 446 Kb - Windows Installer for Python 2.5

Please note that Biopython 1.48 and older used mxTextTools 2.0 in some of the parsers. There were a few niggles with mxTextTools 3.0, so ideally install the older mxTextTools 2.0.
