gh extension install <repository> [flags]

Install a GitHub CLI extension from a GitHub or local repository.

For GitHub repositories, the repository argument can be specified in OWNER/REPO format or as a full repository URL. The URL format is useful when the repository is not hosted on github.com.

For remote repositories, the GitHub CLI first looks for the release artifacts assuming that it's a binary extension i.e. prebuilt binaries provided as part of the release. In the absence of a release, the repository itself is cloned assuming that it's a script extension i.e. prebuilt executable or script exists on its root.

The --pin flag may be used to specify a tag or commit for binary and script extensions respectively, the latest version is used otherwise.

For local repositories, often used while developing extensions, use . as the value of the repository argument. Note the following:

• After installing an extension from a locally cloned repository, the GitHub CLI will manage this extension as a symbolic link (or equivalent mechanism on Windows) pointing to an executable file with the same name as the repository in the repository's root. For example, if the repository is named gh-foobar, the symbolic link will point to gh-foobar in the extension repository's root.
• When executing the extension, the GitHub CLI will run the executable file found by following the symbolic link. If no executable file is found, the extension will fail to execute.
• If the extension is precompiled, the executable file must be built manually and placed in the repository's root.
