Installing Homebrew on macOS

Question

According to the Homebrew site, to install it, I need to type:

brew install wget

I get an error message:

-bash: brew: command not found

Found this answer. The problem, however, is I don't see brew in /usr/local/bin.

I added the below line to my .bashrc file

export PATH=/usr/local/bin:$PATH

Still getting the command not found error.

How do I install Homebrew on macOS?

It's on the top of the Homebrew homepage.

From a Terminal prompt:

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

The command brew install wget is an example of how to use Homebrew to install another application (in this case, wget) after brew is already installed.

Historic...

Before about 2020, the command given on the Homebrew page was:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

After "installing" you need to do something else: ```Add Homebrew to your PATH in /Users/username/.bash_profile: echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/username/.bash_profile eval "$(/opt/homebrew/bin/brew shellenv)" ``` – M. Beausoleil Mar 26 '21 at 00:48

Actually, after the installation ends, there is a `next steps` section at the bottom of the terminal, there are 2 steps to run like: `echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/[user]/.zprofile` and `eval "$(/opt/homebrew/bin/brew shellenv)"` – JORGE GARNICA Aug 11 '21 at 06:22

Whether the `export` should go to `.zshrc` or `.bash_profile` depends on your login shell. New user accounts default to Zsh but Bash is still an option, and will probably be your shell if you created your account on an older version of macOS where Bash was the default, or you subsequently explicitly configured Bash as your shell. – tripleee Jan 09 '21 at 12:49

I might be late to the party, but there is a cool website where you can search for the packages and it will list the necessary command to install the stuff. BrewInstall is the website.

However you can install wget with the following command:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install wget

Hope this helps :)

On an out of the box MacOS High Sierra 10.13.6

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Gives the following error:

curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option.

If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL).

If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option.

HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.

Solution: Just add a k to your Curl Options

$ ruby -e "$(curl -fsSLk https://raw.githubusercontent.com/Homebrew/install/master/install)"

first, install the homebrew by pasting the command in the mac terminal

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

then edit your .bashrc file

vi .bashrc

paste the below command at the end and save it

export PATH=/opt/homebrew/bin:$PATH

to save simply type :wq and press enter

if bashrc file is not there then simply create and then edit the file, to create type

touch ~/.bashrc

and then simply run the command

source ~/.bashrc

now try to use the brew command hopefully it will work now

Update: if you are in M1 mac then after installing homebrew just run the command mentioned below and reload the terminal

echo "export PATH=/opt/homebrew/bin:$PATH" >> ~/.zshrc

Here is a version that wraps the homebrew installer in a bash function that can be run from your deployment scripts:

install_homebrew_if_not_present() {
    echo "Checking for homebrew installation"
    which -s brew
    if [[ $? != 0 ]] ; then
        echo "Homebrew not found. Installing..."
        ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    else
        echo "Homebrew already installed! Updating..."
        brew update
    fi
}

And another function which will install a homebrew formula if it is not already installed:

brew_install () {       
    if brew ls --versions $1 > /dev/null; then
        echo "already installed: $1"
    else
        echo "Installing forumula: $1..."
        brew install $1
    fi
}

Once you have these functions defined you can use them as follows in your bash script:

install_homebrew_if_not_present
brew_install wget
brew_install openssl
...

Then try to download and install command line tool from https://developer.apple.com/download/more/ for your particular Mac os and Xcode version.

Following command doesn't work if your are under proxy.

Instead user following -

ruby -e "$(curl -x http://DOMAIN%5cUSER_NAME:PASSWORD@PROXY:PORT -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Note we have to use %5c instead of "\" Similarly if your password has any special character replace it with unicode e.g for @ use %40 Refer this Unicodes

Replace above command with your own params

DOMAIN - Your Domain

USER_NAME - Your User Name

PASSWORD - password

PROXY - 10.10.10.10

PORT - 8080

"Domain" apparently means Active Directory user group here. It makes sense if you are a Windows victim, but is probably only confusing to everybody else. — tripleee, Jan 09 '21 at 12:53

For Users who installed homebrew for local user account using Untar Anywhere method in MacOS Ventura - M2 pro:

Step 1: Create ~/.zprofile if not there already: touch ~/.zprofile , check with ls -a

Step 2: Open nano ~/.zprofile

Step 3: Paste the eval command portion with appropriate User name: eval "$(/Users/rakibulhaq/Applications/homebrew/bin/brew shellenv)" here, rakibulhaq is a sample user name which should be replaced with your user name.

Not sure why nobody mentioned this : when you run the installation command from the official site, in the final lines you would see something like below, and you need to follow the ==> Next steps:

==> Installation successful!

==> Homebrew has enabled anonymous aggregate formulae and cask analytics.
Read the analytics documentation (and how to opt-out) here:
  https://docs.brew.sh/Analytics
No analytics data has been sent yet (or will be during this `install` run).

==> Homebrew is run entirely by unpaid volunteers. Please consider donating:
  https://github.com/Homebrew/brew#donations

==> Next steps:
- Add Homebrew to your PATH in /Users/{YOUR USER NAME}/.bash_profile:
    echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/{YOUR USER NAME}/.bash_profile
    eval $(/opt/homebrew/bin/brew shellenv)
