mac installation go swagger error with the following message `open /usr/local/go/bin/swag: permission denied`

I run the following command to install swag and the error message is as follows. I hope it helps.

MacBook-Pro~: go get -u github.com/swaggo/swag/cmd/swag                                                                                                                                                                                   1 ↵  5434  14:55:27

I installed go via the pkg package, and here are my environment variables.

How do I change the permissions, am I installing it incorrectly, or do I need to change the environment variables?

It appears your $GOPATH is set to /usr/local/go/. Verify by running echo $GOPATH in the terminal.

/usr/local/go is usually owned by user root. You personal user is not allowed to write stuff there, hence the error.

You have a couple of options:

If you have been working with go before make sure you copy the directories /usr/local/go/bin, /usr/local/go/pkg and /usr/local/go/src to your new $GOPATH.
