When I try to install terragrunt on macos with brew, I get the following error:

==> Installing dependencies for terragrunt: terraform
Error: terraform is already installed from hashicorp/tap!
Please `brew uninstall terraform` first."

CodePudding user response：

Since you have terraform already installed, run the below to just install terragrunt

$ brew install --ignore-dependencies terragrunt

CodePudding user response：

To avoid this error, you must unlink terraform before installing terragrunt:

brew unlink terraform && brew install terragrunt && brew link terraform
