15 Deprecated Python Versions

17 Python == 2.7. Python 2.7 support will be removed on January 1, 2020.
22 gRPC Python is available for Linux, macOS, and Windows.
27 If you are installing locally...
33 Else system wide (on Ubuntu)...
37 $ sudo pip install grpcio
39 If you're on Windows make sure that you installed the :code:`pip.exe` component
40 when you installed Python (if not go back and install it!) then invoke:
44 $ pip.exe install grpcio
46 Windows users may need to invoke :code:`pip.exe` from a command line ran as
49 n.b. On Windows and on Mac OS X one *must* have a recent release of :code:`pip`
50 to retrieve the proper wheel from PyPI. Be sure to upgrade to the latest
53 Installing From Source
54 ~~~~~~~~~~~~~~~~~~~~~~
56 Building from source requires that you have the Python headers (usually a
57 package named :code:`python-dev`).
61 $ export REPO_ROOT=grpc # REPO_ROOT can be any directory of your choice
62 $ git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc $REPO_ROOT
64 $ git submodule update --init
66 # For the next two commands do `sudo pip install` if you get permission-denied errors
67 $ pip install -rrequirements.txt
68 $ GRPC_PYTHON_BUILD_WITH_CYTHON=1 pip install .
70 You cannot currently install Python from source on Windows. Things might work
71 out for you in MSYS2 (follow the Linux instructions), but it isn't officially
72 supported at the moment.
79 * **... see a** :code:`pkg_resources.VersionConflict` **when I try to install
82 This is likely because :code:`pip` doesn't own the offending dependency,
83 which in turn is likely because your operating system's package manager owns
84 it. You'll need to force the installation of the dependency:
86 :code:`pip install --ignore-installed $OFFENDING_DEPENDENCY`
88 For example, if you get an error like the following:
92 Traceback (most recent call last):
93 File "<string>", line 17, in <module>
95 File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 509, in find
96 raise VersionConflict(dist, req)
97 pkg_resources.VersionConflict: (six 1.8.0 (/usr/lib/python2.7/dist-packages), Requirement.parse('six>=1.10'))
99 You can fix it by doing:
103 sudo pip install --ignore-installed six
105 * **... see the following error on some platforms**
109 /tmp/pip-build-U8pSsr/cython/Cython/Plex/Scanners.c:4:20: fatal error: Python.h: No such file or directory
112 compilation terminated.
114 You can fix it by installing `python-dev` package. i.e
118 sudo apt-get install python-dev
