gRPC Python |
||||
=========== |
||||
|
||||
Package for GRPC Python. |
||||
Package for gRPC Python. |
||||
|
||||
Dependencies |
||||
Installation |
||||
------------ |
||||
|
||||
Ensure you have installed the gRPC core. On Mac OS X, install homebrew_. |
||||
Run the following command to install gRPC Python. |
||||
gRPC Python is available for Linux and Mac OS X running Python 2.7. |
||||
|
||||
From PyPI |
||||
~~~~~~~~~ |
||||
|
||||
If you are installing locally... |
||||
|
||||
:: |
||||
|
||||
$ curl -fsSL https://goo.gl/getgrpc | bash -s python |
||||
$ pip install grpcio |
||||
|
||||
Else system wide (on Ubuntu)... |
||||
|
||||
:: |
||||
|
||||
This will download and run the [gRPC install script][] to install grpc core. The script then uses pip to install this package. It also installs the Protocol Buffers compiler (_protoc_) and the gRPC _protoc_ plugin for python. |
||||
$ sudo pip install grpcio |
||||
|
||||
From Source |
||||
~~~~~~~~~~~ |
||||
|
||||
Building from source requires that you have the Python headers (usually a |
||||
package named `python-dev`). |
||||
|
||||
:: |
||||
|
||||
Otherwise, `install from source`_ |
||||
$ export REPO_ROOT=grpc |
||||
$ git clone https://github.com/grpc/grpc.git $REPO_ROOT |
||||
$ cd $REPO_ROOT |
||||
$ pip install . |
||||
|
||||
.. _`install from source`: https://github.com/grpc/grpc/blob/master/src/python/README.md#building-from-source |
||||
.. _homebrew: http://brew.sh |
||||
.. _`gRPC install script`: https://raw.githubusercontent.com/grpc/homebrew-grpc/master/scripts/install |
||||
Note that `$REPO_ROOT` can be assigned to whatever directory name floats your |
||||
fancy. |
