Installing / Upgrading

PyMongo is in the Python Package Index.

Warning

Do not install the “bson” package from pypi. PyMongo comes with its own bson package; doing “pip install bson” or “easy_install bson” installs a third-party package that is incompatible with PyMongo.

Installing with pip

We recommend using pip to install pymongo on all platforms:

$ python3 -m pip install pymongo

To get a specific version of pymongo:

$ python3 -m pip install pymongo==3.5.1

To upgrade using pip:

$ python3 -m pip install --upgrade pymongo

Dependencies

PyMongo supports CPython 3.8+ and PyPy3.9+.

Required dependencies

Support for mongodb+srv:// URIs requires dnspython

Optional dependencies

GSSAPI authentication requires pykerberos on Unix or WinKerberos on Windows. The correct dependency can be installed automatically along with PyMongo:

$ python3 -m pip install "pymongo[gssapi]"

MONGODB-AWS authentication requires pymongo-auth-aws:

$ python3 -m pip install "pymongo[aws]"

OCSP requires PyOpenSSL, requests and service_identity:

$ python3 -m pip install "pymongo[ocsp]"

Wire protocol compression with snappy requires python-snappy:

$ python3 -m pip install "pymongo[snappy]"

Wire protocol compression with zstandard requires zstandard:

$ python3 -m pip install "pymongo[zstd]"

Client-Side Field Level Encryption requires pymongocrypt and pymongo-auth-aws:

$ python3 -m pip install "pymongo[encryption]"

You can install all dependencies automatically with the following command:

$ python3 -m pip install "pymongo[gssapi,aws,ocsp,snappy,zstd,encryption]"

Installing from source

If you’d rather install directly from the source (i.e. to stay on the bleeding edge), install the C extension dependencies then check out the latest source from GitHub and install the driver from the resulting tree:

$ git clone https://github.com/mongodb/mongo-python-driver.git pymongo
$ cd pymongo/
$ pip install .

Installing from source on Unix

To build the optional C extensions on Linux or another non-macOS Unix you must have the GNU C compiler (gcc) installed. Depending on your flavor of Unix (or Linux distribution) you may also need a python development package that provides the necessary header files for your version of Python. The package name may vary from distro to distro.

Debian and Ubuntu users should issue the following command:

$ sudo apt-get install build-essential python-dev

Users of Red Hat based distributions (RHEL, CentOS, Amazon Linux, Oracle Linux, Fedora, etc.) should issue the following command:

$ sudo yum install gcc python-devel

Installing from source on macOS / OSX

If you want to install PyMongo with C extensions from source you will need the command line developer tools. On modern versions of macOS they can be installed by running the following in Terminal (found in /Applications/Utilities/):

xcode-select --install

For older versions of OSX you may need Xcode. See the notes below for various OSX and Xcode versions.

Snow Leopard (10.6) - Xcode 3 with ‘UNIX Development Support’.

Snow Leopard Xcode 4: The Python versions shipped with OSX 10.6.x are universal binaries. They support i386, PPC, and x86_64. Xcode 4 removed support for PPC, causing the distutils version shipped with Apple’s builds of Python to fail to build the C extensions if you have Xcode 4 installed. There is a workaround:

# For some Python builds from python.org
$ env ARCHFLAGS='-arch i386 -arch x86_64' python -m easy_install pymongo

See http://bugs.python.org/issue11623 for a more detailed explanation.

Lion (10.7) and newer - PyMongo’s C extensions can be built against versions of Python 3.8+ downloaded from python.org. In all cases Xcode must be installed with ‘UNIX Development Support’.

Xcode 5.1: Starting with version 5.1 the version of clang that ships with Xcode throws an error when it encounters compiler flags it doesn’t recognize. This may cause C extension builds to fail with an error similar to:

clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]

There are workarounds:

# Apple specified workaround for Xcode 5.1
# easy_install
$ ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future easy_install pymongo
# or pip
$ ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install pymongo

# Alternative workaround using CFLAGS
# easy_install
$ CFLAGS=-Qunused-arguments easy_install pymongo
# or pip
$ CFLAGS=-Qunused-arguments pip install pymongo

Installing from source on Windows

If you want to install PyMongo with C extensions from source the following requirements apply to both CPython and ActiveState’s ActivePython:

Windows

Install Visual Studio 2015+.

Installing Without C Extensions

By default, the driver attempts to build and install optional C extensions (used for increasing performance) when it is installed. If any extension fails to build the driver will be installed anyway but a warning will be printed.

If you wish to install PyMongo without the C extensions, even if the extensions build properly, it can be done using a command line option to pip install:

$ NO_EXT=1 python -m pip install .

Installing a beta or release candidate

MongoDB, Inc. may occasionally tag a beta or release candidate for testing by the community before final release. These releases will not be uploaded to pypi but can be found on the GitHub tags page. They can be installed by passing the full URL for the tag to pip:

$ python3 -m pip install https://github.com/mongodb/mongo-python-driver/archive/4.4.0b0.tar.gz
