Not in Kansas anymore - apparently I don't exist

To narrow things down, I ran: -

brew upgrade

but that failed with much the same: -

==> Upgrading tektoncd/tools/tektoncd-cli 0.8.0 -> 0.15.0 

==> Downloading https://github.com/tektoncd/cli/releases/download/v0.15.0/tkn_0.15.0_Darwin_x86_64.tar.gz

Already downloaded: /Users/hayd/Library/Caches/Homebrew/downloads/d911addd12ba79ea06e5d8d0002a0523ec0b53d6aa5407a94f6e9836f3ff6fa5--tkn_0.15.0_Darwin_x86_64.tar.gz

Error: An exception occurred within a child process:

  ArgumentError: user david_hay@uk.ibm.com doesn't exist

Following this: -

Heroku cli (brew install heroku): ArgumentError: user emixam23 doesn't exist

I checked my environment: -

printenv | grep david_hay@uk.ibm.com

which returned: -

USER=david_hay@uk.ibm.com

Given that my macOS user is actually hayd, I suspect that this is the issue.

I reset that environment variable: -

export USER=hayd

and tried again: -

brew upgrade tektoncd/tools/tektoncd-cli
