This page shows how to install client libraries for the Memorystore for Memcached API so you can connect to the API with the language of your choice.
Installing the client library
C++
See Setting up a C++ development environment for details about this client library's requirements and install dependencies.
C#
Install theGoogle.Cloud.Memcache.V1Beta2
package in Visual Studio. See the Google Cloud .NET Memcached Installation documentation for more details.
Go
go get cloud.google.com/go/memcache/apiv1beta2
Java
If you are using Maven with BOM, add this to your pom.xml file
<dependencyManagement> <dependencies> <dependency> <groupId>com.google.cloud</groupId> <artifactId>libraries-bom</artifactId> <version>20.8.0</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>com.google.cloud</groupId> <artifactId>google-cloud-memcache</artifactId> </dependency>
If you are using Maven without BOM, add this to your dependencies:
<dependency> <groupId>com.google.cloud</groupId> <artifactId>google-cloud-memcache</artifactId> <version>0.2.1</version> </dependency>
If you are using Gradle, add this to your dependencies:
compile 'com.google.cloud:google-cloud-memcache:0.2.1'
If you are using SBT, add this to your dependencies:
libraryDependencies += "com.google.cloud" % "google-cloud-memcache" % "0.2.1"
Node.js
npm install @google-cloud/memcache
Python
For more on setting up your Python development environment, refer to Python Development Environment Setup Guide. Mac/Linuxpip install virtualenv virtualenv <your-env> source <your-env>/bin/activate <your-env>/bin/pip install google-cloud-memcacheWindows
pip install virtualenv virtualenv <your-env> <your-env>\Scripts\activate <your-env>\Scripts\pip.exe install google-cloud-memcache
Setting up authentication
To run the client library, you must first set up authentication by creating a service account and setting an environment variable.
Create a service account:
In the Google Cloud console, go to the Create service account page.
In the Service account name field, enter a name. The Google Cloud console fills
in the Service account ID field based on this name.
In the Service account description field, enter a description. For example,
Grant the Project > Owner role to the service account.
To grant the role, find the Select a role list, then select
Project > Owner.
Click Done to finish creating the service account.
Do not close your browser window. You will use it in the next step.
Create a service account key:

Provide authentication credentials to your application code by setting the
environment variable GOOGLE_APPLICATION_CREDENTIALS
. This
variable applies only to your current shell session. If you want the variable
to apply to future shell sessions, set the variable in your shell startup file,
for example in the ~/.bashrc
or ~/.profile
file.
Linux or macOS
export GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH
"
Replace KEY_PATH
with the path of the JSON file that contains your credentials.
For example:
export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/service-account-file.json"
Windows
For PowerShell:
$env:GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH
"
Replace KEY_PATH
with the path of the JSON file that contains your credentials.
For example:
$env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\username\Downloads\service-account-file.json"
For command prompt:
set GOOGLE_APPLICATION_CREDENTIALS=KEY_PATH
Replace KEY_PATH
with the path of the JSON file that contains your credentials.
