Homebrew not working on macOS due to invalid version value

Question

whenever I try to use anything brew related, or even just type brew on my computer, this error appears:

"/usr/local/Library/Homebrew/version.rb:186:in `initialize': Version value must be a string (TypeError)
    from /usr/local/Library/Homebrew/os/mac/version.rb:24:in `initialize'
    from /usr/local/Library/Homebrew/os/mac.rb:15:in `new'
    from /usr/local/Library/Homebrew/os/mac.rb:15:in `version'
    from /usr/local/Library/brew.rb:31:in `<main>'"

I am fairly new to developing, so I may be asking a stupid question, and I do not know what to try next.

Answer 1

There are similar questions related to what you have right now. Here are some things that you can try:

Upgrade homebrew, run the following lines in sequence:

brew update-reset
brew upgrade

Or Re-install homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

After doing either options above you can test if homebrew is working by running the following in your terminal:

brew --version

For good measure try running the following after all other steps mentioned:

brew doctor
