Trying to install Hugo via Homebrew - “Could Not Resolve HEAD to a Revision”

问题

I'm trying to take a stab at a new site using Hugo, and I am stuck during installation. I've installed Homebrew and when running the version, I get the following:

~ % brew --version
Homebrew 2.7.2
Homebrew/homebrew-core (no git repository)
Homebrew/homebrew-cask (git revision b96680c; last commit 2021-01-07)

And when I run brew install hugo

I get the following:

~ % brew install hugo
fatal: Could not resolve HEAD to a revision
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "hugo".
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

What am I doing wrong? This is the first time working in home-brew.

Edit: when running brew install --verbose Hugo, I get the following warnings:

% brew install --verbose hugo

fatal: Could not resolve HEAD to a revision

==> Searching for similarly named formulae...

Error: No similarly named formulae found.

Error: No available formula or cask with the name "hugo".

==> Searching for a previously deleted formula (in the last month)...

Error: No previously deleted formula found.

==> Searching taps on GitHub...

回答1:

As illustrated by this thread, this might be related to brew itself, not so much hugo.

brew install --verbose hugo

This should give you more and allow you to see at which step brew is stuck.

[where the error occurred], I changed into that directory to find that it was empty – all that was in the dir was a .git/ folder and nothing else.

So, to restore the missing contents, I used git fetch and git pull --rebase.

No available formula or cask with the name "hugo".

That points to a brew configuration issue, since there is a formulae for hugo

Packages are installed according to their formulae, which live in /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula

Check that Formula folder and see if hugo is missing there.
If not, at least try brew extract hugo inside a new tap.

brew tap-new gohugoio/hugo
brew extract --version 0.80.0 hugo gohugoio/hugo
brew install gohugoio/hugo/hugo@0.80.0

回答2:

use git -C $(brew --repository homebrew/core) checkout master or git -C $(brew --repository homebrew/core) reset --hard HEAD.
