I am assuming that the user you're logged in as doesn't have permissions to run go.
To find that out, run the following
$ which go
/usr/local/go/bin/go
$ ls -l $(which go)
-rwxr-xr-x 1 root wheel 12896684 Jan 24 01:28 /usr/local/go/bin/go
From the above we know that the owner is root and group owner is wheel.
Now run echo $USER to see if who is logged in user.
Since you're getting permission denied to run go as $USER, you may want to add the user into the group mentioned in ls -l. So, run the below.
$ usermod -aG $USER wheel
And reboot the system! Then try go env again to see if it works.
-a is for append
-G is for which groups to append
usermod docs
Remember wheel is the group owner that I got while running ls -l. Yours might be different.
This usermod command is for ubuntu. In your case, it is raspberry pi so raspbian OS. Find out the correct options as it changes from OS to OS.
