Supported Python Versions

Python >= 3.7

Installation

gRPC Python is available for Linux, macOS, and Windows.

Installing From PyPI

If you are installing locally...

::

  $ pip install grpcio

Else system wide (on Ubuntu)...

::

  $ sudo pip install grpcio

If you're on Windows make sure that you installed the :code:`pip.exe` component
when you installed Python (if not go back and install it!) then invoke:

::

  $ pip.exe install grpcio

Windows users may need to invoke :code:`pip.exe` from a command line ran as
administrator.

n.b. On Windows and on Mac OS X one *must* have a recent release of :code:`pip`
to retrieve the proper wheel from PyPI. Be sure to upgrade to the latest
version!

Installing From Source

Building from source requires that you have the Python headers (usually a package named :code:python-dev).

::

$ export REPO_ROOT=grpc # REPO_ROOT can be any directory of your choice $ git clone -b RELEASE_TAG_HERE https://github.com/grpc/grpc $REPO_ROOT $ cd $REPO_ROOT $ git submodule update --init

For the next two commands do sudo pip install if you get permission-denied errors

$ pip install -r requirements.txt $ GRPC_PYTHON_BUILD_WITH_CYTHON=1 pip install .

You cannot currently install Python from source on Windows. Things might work out for you in MSYS2 (follow the Linux instructions), but it isn't officially supported at the moment.

Troubleshooting

Help, I ...

* **... see a** :code:`pkg_resources.VersionConflict` **when I try to install
  grpc**

  This is likely because :code:`pip` doesn't own the offending dependency,
  which in turn is likely because your operating system's package manager owns
  it. You'll need to force the installation of the dependency:

  :code:`pip install --ignore-installed $OFFENDING_DEPENDENCY`

  For example, if you get an error like the following:

  ::

    Traceback (most recent call last):
    File "<string>", line 17, in <module>
     ...
    File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 509, in find
      raise VersionConflict(dist, req)
    pkg_resources.VersionConflict: (six 1.8.0 (/usr/lib/python2.7/dist-packages), Requirement.parse('six>=1.10'))

  You can fix it by doing:

  ::

    sudo pip install --ignore-installed six

* **... see the following error on some platforms**

  ::

    /tmp/pip-build-U8pSsr/cython/Cython/Plex/Scanners.c:4:20: fatal error: Python.h: No such file or directory
    #include "Python.h"
                    ^
    compilation terminated.

  You can fix it by installing `python-dev` package. i.e

  ::

    sudo apt-get install python-dev
