Can I use Homebrew on Ubuntu? - linux

Question

I just tried to use Homebrew and Linuxbrew to install packages on my Ubuntu Server but both failed. This is how I tried to install them:
sudo apt-get install build-essential curl git m4 ruby texinfo libbz2-dev libcurl4-openssl-dev libexpat-dev libncurses-dev zlib1g-dev
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/linuxbrew/go/install)"
I got the following warning:
Warning: /home/tong/.linuxbrew/bin is not in your PATH.
I vi my bash.bashrc in home/etc and add this:
export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"
Then I tried brew doctor but got No command 'brew' found. How am I able to use Homebrew on Ubuntu?

Answer 1

As of February 2018, installing brew on Ubuntu (mine is 17.10) machine is as simple as:
sudo apt install linuxbrew-wrapper
Then, on first brew execution (just type brew --help) you will be asked for two installation options:
me#computer:~/$ brew --help
==> Select the Linuxbrew installation directory
- Enter your password to install to /home/linuxbrew/.linuxbrew (recommended)
- Press Control-D to install to /home/me/.linuxbrew
- Press Control-C to cancel installation
[sudo] password for me:
For recommended option type your password (if your current user is in sudo group), or, if you prefer installing all the dependencies in your own home folder, hit Ctrl+D. Enjoy.

Answer 2

I just tried installing it using the ruby command but somehow the dependencies are not resolved hence brew does not completely install. But, try installing by cloning:
git clone https://github.com/Homebrew/linuxbrew.git ~/.linuxbrew
and then add the following to your .bash_profile:
export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"
It should work..

Answer 3

as of august 2020 (works for kali linux as well)
sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
export brew=/home/linuxbrew/.linuxbrew/bin
test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv)
test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
test -r ~/.profile && echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.profile // for ubuntu and debian

Answer 4

The following steps worked for me:
Clone it from github
git clone https://github.com/Homebrew/linuxbrew.git ~/.linuxbrew
Open your .bash_profile file using vi ~/.bash_profile
Add these lines
export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"
Then type the following lines in your terminal
export PATH=$HOME/.linuxbrew/bin:$PATH
hash -r
Yes, it is done. Type brew in your terminal to check its existence.

You can just follow instructions from the Homebrew on Linux docs, but I think it is better to understand what the instructions are trying to achieve.
Understanding the installation steps can save some time
Step 1: Choose location
First of all, it is important to understand that linuxbrew will be installed on the /home directory and not inside /home/your-user (the ~ directory).
(See the reason for that at the end of answer).
Keep this in mind when you run the other steps below.
Step 2: Add linuxbrew binaries to /home :
The installation script will do it for us:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Step 3: Check that /linuxbrew was added to the relevant location
This can be done by simply navigating to /home.
Notice that the docs are showing it as a one-liner by adding test -d <linuxbrew location> before each command.
(Read more about the test command in here).
Step 4: Export relevant environment variables to terminal
We need to add linuxbrew to PATH and add some more environment variables to the current terminal.
We can just add the following exports to terminal (wait don't do it..):
export PATH="/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin${PATH+:$PATH}";
export HOMEBREW_PREFIX="/home/linuxbrew/.linuxbrew";
export HOMEBREW_CELLAR="/home/linuxbrew/.linuxbrew/Cellar";
export HOMEBREW_REPOSITORY="/home/linuxbrew/.linuxbrew/Homebrew";
export MANPATH="/home/linuxbrew/.linuxbrew/share/man${MANPATH+:$MANPATH}:";
export INFOPATH="/home/linuxbrew/.linuxbrew/share/info:${INFOPATH:-}";
Or simply run (If your linuxbrew folder is on other location then /home - change the path):
eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
(*) Because brew command is not yet identified by the current terminal (this is what we're solving right now) we'll have to specify the full path to the brew binary: /home/linuxbrew/.linuxbrew/bin/brew shellenv
Test this step by:
1 ) Run brew from current terminal to see if it identifies the command.
2 ) Run printenv and check if all environment variables were exported and that you see /home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin on PATH.
Step 5: Ensure step 4 is running on each terminal
We need to add step 4 to ~/.profile (in case of Debian/Ubuntu):
echo "eval \$($(brew --prefix)/bin/brew shellenv)" >> ~/.profile
For CentOS/Fedora/Red Hat - replace ~/.profile with ~/.bash_profile.
Step 6: Ensure that ~/.profile or ~/.bash_profile are being executed when new terminal is opened
If you executed step 5 and failed to run brew from new terminal - add a test command like echo "Hi!" to ~/.profile or ~/.bash_profile.
If you don't see Hi! when you open a new terminal - go to the terminal preferences and ensure that the attribute of 'run command as login shell' is set.

Why the installation script installs Homebrew to /home/linuxbrew/.linuxbrew - from here:
The installation script installs Homebrew to
/home/linuxbrew/.linuxbrew using sudo if possible and in your home
directory at ~/.linuxbrew otherwise. Homebrew does not use sudo
after installation. Using /home/linuxbrew/.linuxbrew allows the
use of more binary packages (bottles) than installing in your personal
home directory.
The prefix /home/linuxbrew/.linuxbrew was chosen so that users
without admin access can ask an admin to create a linuxbrew role
account and still benefit from precompiled binaries.
If you do not yourself have admin privileges, consider asking your
admin staff to create a linuxbrew role account for you with home
directory /home/linuxbrew.

Linux is now officially supported in brew - see the Homebrew 2.0.0 blog post. As shown on https://brew.sh, just copy/paste this into a command prompt:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Answer 7

Because all previous answers doesn't work for me for ubuntu 14.04
here what I did, if any one get the same problem:
git clone https://github.com/Linuxbrew/brew.git ~/.linuxbrew
PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$(brew --prefix)/share/man:$MANPATH"
export INFOPATH="$(brew --prefix)/share/info:$INFOPATH"
then
sudo apt-get install gawk
sudo yum install gawk
brew install hello
you can follow this link for more information.

October 2019 - Ubuntu 18.04 on WSL with oh-my-zsh;
the instructions here worked perfectly -
(first, install pre-requisites using sudo apt-get install build-essential curl file git)
finally create a ~/.zprofile with the following contents:
emulate sh -c '. ~/.profile'

Answer 9

Whta to do
cd /home/linuxbrew/.linuxbrew/bin
./brew doctor
You will get what path to export
echo 'export PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"' >> ~/.zshrc
