How to do alternative install of Homebrew - macos

Question

Ok, well it's just been one of those nights where you spend hours and hours trying to get something to work, and you just keep getting weird errors, so if someone could help me I would greatly appreciate. After hours of trying to update Maven from 3.0.4 to 3.1.1 or 3.2.2 I've decided it's just not going to happen (I've tried almost everything I can find online, but I'm afraid to try to do to much in terminal) and I'm trying to install homebrew to make it easier. When I try to do the normal homebrew install I get an error that says:
dyld: lazy symbol binding failed: Symbol not found: ___strlcpy_chk
Referenced from: /usr/local/git/bin/git
Expected in: /usr/lib/libSystem.B.dylib
dyld: Symbol not found: ___strlcpy_chk
Referenced from: /usr/local/git/bin/git
Expected in: /usr/lib/libSystem.B.dylib
Failed during: git init -q
So then, I tried to do the alternative install method, but at this point I'm just so annoyed, and I don't get what it wants me to do. If anyone could give me some at least kind of detailed explanation for what to do I would be extremely grateful.
Here's where I'm looking at alternative installs: https://github.com/Homebrew/homebrew/wiki/Installation
The problem is I don't even really know what they mean by "untar" and "extract."
Thanks so much to anyone who can help
When I enter
ls -l /usr/local | pbcopy
I get:

Ok, so let's do an alternative install of homebrew:
cd /usr/local
mkdir homebrew
curl -L https://github.com/Homebrew/homebrew/tarball/master | tar xz --strip 1 -C homebrew
If that works, you just need to find the directory where the file brew is located and then add that to your PATH
So
find /usr/local -name brew
Let's suppose the previous command results in
/usr/local/homebrew/bin/brew
we take brew off the end (because we want to know its directory only) and we add that to the start of our PATH
export PATH=/usr/local/homebrew/bin:$PATH
Now we should be able to run
brew doctor
Also, we need to add that export PATH=.... command to our login sequence so our shell knows how to find brew every time we login. So add that line to the end of your ~/.profile

Ok, take a deep breath, and relax :-)
homebrew is a great choice on the Mac, so the pain should be worth it. I suspect you have a customised PATH and customised environment variables which are stopping the homebrew installation. You can either set your PATH and environment variables back to their default settings, or, if that is simpler, just add a new user to your Mac and log in as the new user with a standard environment and then install homebrew using the standard method.
To look at your PATH and environment variables, use these commands:
echo $PATH
set
or
set | grep -i LIB
to look for any customised DYLD_LIBRARY_PATH
Once you have it installed, try running
brew doctor
to check your setup before adding maven and other packages.
