# CDK Manual Installation Instructions The CDK is also distributed as a single zip file which contains the same packages that we also publish to the various package managers. You can download the zip file from the [Releases](http://github.com/aws/aws-cdk/releases) page on GitHub. The zip file comes with a signature so the integrity of the download can be verified (see below). ## Installation overview After extracting the archive, follow the following instructions: ### Installing the CLI The CLI (the `cdk` command) is always installed using npm, regardless of your language. ``` npm install -g /path/to/zip/js/aws-cdk-1.2.3.tgz ``` ### TypeScript/JavaScript (npm) Run `npm install` on the desired tarballs: ``` # Install individual packages into your current project npm install /path/to/zip/js/[email protected] ... ``` ### Python (pip) Run `pip install` on the `.whl` files you want to install into your current virtual env (or the global Python install): ``` # Install all wheels into your current Python env pip install path/to/zip/python/*.whl ``` ### Java (Maven) Install the packages using Maven: ``` # For every package you want to install mvn install:install-file -Dfile=/path/to/zip/java/software/amazon/awscdk/dynamodb/1.2.3/dynamodb-1.2.3.jar mvn install:install-file -Dfile=/path/to/zip/java/software/amazon/awscdk/dynamodb/1.2.3/dynamodb-1.2.3-sources.jar mvn install:install-file -Dfile=/path/to/zip/java/software/amazon/awscdk/dynamodb/1.2.3/dynamodb-1.2.3-javadoc.jar ``` ### .NET (NuGet) From a NuGet shell: ``` # For every package you want to install Install-Package C:\Path\To\Zip\dotnet\Amazon.CDK.AWS.Events.1.2.3.nupkg ``` ## Verifying the integrity of your download You can verify that your download is complete and correct by validating its signature against our public signing key. To do so, you need the following things: * [GNU Privacy Guard](https://gnupg.org/) needs to be installed. * Download our public key: https://docs.aws.amazon.com/cdk/v2/guide/pgp-keys.html * Make sure you have downloaded both `aws-cdk-x.y.z.zip` and `aws-cdk-x.y.z.zip.sig`. Then run the following commands: ```shell gpg --import cdk-team.asc gpg --verify aws-cdk-x.y.z.zip.sig aws-cdk-x.y.z.zip ``` If everything is correct, the output will contain the line: ``` gpg: Good signature from "AWS CDK Team " ``` If you obtained via the above URL, you can ignore the following message: ``` gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner. ```
