Use any of the following for a pain-free installation:

* If you have [`go`](https://go.dev/doc/install) installed, you can run:
* If you have [`Go 1.27.0 or newer`](https://go.dev/doc/install) installed, you can run:
```shell
go install github.com/dependabot/cli/cmd/dependabot@latest
```
The benefit of this method is that re-running the command will always update to the latest version.
The minimum Go version is required by the CLI's Sigstore dependencies.
If `GOTOOLCHAIN=local` is set, Go cannot download a newer toolchain automatically;
upgrade Go before installing, or use a pre-built binary instead.
If you must build with Go 1.26, use
`go install github.com/dependabot/cli/cmd/dependabot@v1.95.0`.
This older release omits subsequent fixes and features; prefer a current pre-built binary.
* You can download a pre-built binary from the [releases] page.
* On Mac or Linux, you can run `brew install dependabot`
