11 Supported Python Versions
12 -------------------------
18 gRPC Python is available for Linux, macOS, and Windows.
23 If you are installing locally...
29 Else system wide (on Ubuntu)...
33 $ sudo pip install grpcio
35 If you're on Windows make sure that you installed the :code:`pip.exe` component
36 when you installed Python (if not go back and install it!) then invoke:
40 $ pip.exe install grpcio
42 Windows users may need to invoke :code:`pip.exe` from a command line ran as
45 n.b. On Windows and on Mac OS X one *must* have a recent release of :code:`pip`
46 to retrieve the proper wheel from PyPI. Be sure to upgrade to the latest
49 Installing From Source
50 ~~~~~~~~~~~~~~~~~~~~~~
52 Building from source requires that you have the Python headers (usually a
53 package named :code:`python-dev`).
57 $ export REPO_ROOT=grpc # REPO_ROOT can be any directory of your choice
58 $ git clone -b RELEASE_TAG_HERE https://github.com/grpc/grpc $REPO_ROOT
60 $ git submodule update --init
62 # For the next two commands do `sudo pip install` if you get permission-denied errors
63 $ pip install -rrequirements.txt
64 $ GRPC_PYTHON_BUILD_WITH_CYTHON=1 pip install .
66 You cannot currently install Python from source on Windows. Things might work
67 out for you in MSYS2 (follow the Linux instructions), but it isn't officially
68 supported at the moment.
75 * **... see a** :code:`pkg_resources.VersionConflict` **when I try to install
78 This is likely because :code:`pip` doesn't own the offending dependency,
79 which in turn is likely because your operating system's package manager owns
80 it. You'll need to force the installation of the dependency:
82 :code:`pip install --ignore-installed $OFFENDING_DEPENDENCY`
84 For example, if you get an error like the following:
88 Traceback (most recent call last):
89 File "<string>", line 17, in <module>
91 File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 509, in find
92 raise VersionConflict(dist, req)
93 pkg_resources.VersionConflict: (six 1.8.0 (/usr/lib/python2.7/dist-packages), Requirement.parse('six>=1.10'))
95 You can fix it by doing:
99 sudo pip install --ignore-installed six
101 * **... see the following error on some platforms**
105 /tmp/pip-build-U8pSsr/cython/Cython/Plex/Scanners.c:4:20: fatal error: Python.h: No such file or directory
108 compilation terminated.
110 You can fix it by installing `python-dev` package. i.e
114 sudo apt-get install python-dev
