Supported Python Versions
-------------------------
Python >= 3.8
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
# To include systemd socket-activation feature in the build,
# first install the `libsystemd-dev` package, then :
$ export GRPC_PYTHON_BUILD_WITH_SYSTEMD=1
# 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 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
