How to install composer via homebrew

homebrewinstallPHP

I'm really new to MacOS so maybe this is simple question.

I'm using High Sierra with default PHP 7.1 installed, I've also installed PHP 7.2 running:

curl -s http://php-osx.liip.ch/install.sh | bash -s 7.2

When I run:

brew install composer

I'm getting:

Error: No available formula with the name "composer" 
==> Searching for a previously deleted formula...
Warning: homebrew/core is shallow clone. To get complete history run:
  git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
==> Searching local taps...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.

The question is how to install composer via homebrew? (Maybe I should somehow uninstall PHP I've installed and install PHP via homebrew?)

Best Answer

It's now possible to install composer running

brew install composer

Previous answer (for older versions):

It seems the solution was running:

brew tap homebrew/homebrew-php

and then

brew install composer

After that composer seems to be installed:

composer --version
Composer version 1.5.5 2017-12-01 14:42:57

How to work around a “Could not resolve host: (nil)…” error when installing/using Homebrew

Seems that you have problems connecting to github via https.

While I'm not sure what could cause it and how to fix it, you still can use git with another protocol.

Here's the commands to install homebrew in /usr/local/ from scratch using git:// instead of https://:

cd /usr/local/
git init -q
git remote add origin git://github.com/mxcl/homebrew
git fetch origin master:refs/remotes/origin/master -n
git reset --hard origin/master

That should work. Please notice that if you choose to use another directory for homebrew, you probably will have to append its ./bin directory to your environment PATH variable for comfortable usage.

I see a few issues from what you posted.

error: unable to unlink old 'Library/Homebrew/test/mach/a.out' (Permission denied)

It seems to me you have a permissions issue perhaps from the leftover previous installation of Homebrew. You should remove all traces of the previous installation before you reinstall.

And Homebrew doesn't want to be installed as root

Why on earth would you want to install homebrew as root? The whole point of the project is to keep homebrew in /usr/local so that you don't need sudo.

Warning: It appears you have MacPorts or Fink installed. Software installed with other package managers causes known problems for Homebrew.

You should also ensure MacPorts is uninstalled and that you've uninstalled Fink. They could cause issues with software installed by homebrew.

Warning: An outdated version of Git was detected in your PATH. Git 1.7.10 or newer is required to perform checkouts over HTTPS from GitHub.

This indicates to me that you still have an old version of Git in your PATH, probably installed with another package manager. OS X Mavericks comes with Git version 1.8.5.1

What is the result of the whereis git command from the Terminal? usr/bin/git is the OS X install of Git.

Follow the guides to completely remove previous MacPorts or Fink installs and ensure the old directories are removed from your PATH variable.

PS.

I'll be sad if I can't use Mac OS X as a hacker's Unix

That would make me sad too. :(

I find homebrew invaluable and easy to work with. In summary, it seems you just have old software installed (and perhaps extraneous directories in your PATH) and need to clear it out, check your permissions, and reinstall homebrew from scratch.
