It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
    rm -rf /home/rahn/.linuxbrew/Cellar /home/rahn/.linuxbrew/.git && brew cleanup

This appears to be a bug in your installation of Debian. See for example http://ubuntuforums.org/showthread.php?t=2258760 Please report:

which -a which git-remote-https
ldd `which git-remote-https`
ldd /usr/lib/x86_64-linux-gnu/libhogweed.so.2

[w3ntao]

Yep, something wrong with my git. After fixing the bug:

$ brew

bash: brew: command not found

How do I do for this?

[rwhogg]

Looks like you need /home/rahn/.linuxbrew/bin/ in your path. Can you add it in and try again?

If it's already in your path, you can try either hash -r (Bash) or rehash (Zsh) and then try to run the command again.

[w3ntao]

I get zsh: command not found: brew even I'm at directory /home/rahn/.linuxbrew/bin/

I don't know why.

I'm new to Linux, still google on path editing.

[sjackman]

@tseemann pointed out that this warning gets buried.

Warning: /home/rahn/.linuxbrew/bin is not in your PATH.

It needs to be improved with these instructions: http://linuxbrew.sh/#installation

Add to your .bashrc or .zshrc:

export PATH="$HOME/.linuxbrew/bin:$HOME/.linuxbrew/sbin:$PATH"

[w3ntao]

I append export PATH="$HOME/.linuxbrew/bin:$HOME/.linuxbrew/sbin:$PATH" to the end of ~/.bashrc and terminal prompt:

\ (gedit:2990): WARNING **: Set document metadata failed: Setting attribute metadata::gedit-spell-language not supported

\ (gedit:2990): WARNING **: Set document metadata failed: Setting attribute metadata::gedit-encoding not supported

After saving: $ which brew brew not found

[sjackman]

Open a new terminal window with a new shell. It should work.

[w3ntao]

No, it doesn't... The line has been appended to ~/.bashrc But $PATH remain unchanged. $ echo $PATH /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

[sjackman]

Try instead appending the line to ~/.bash_profile

Also try running in the new terminal:

PATH="$HOME/.linuxbrew/bin:$HOME/.linuxbrew/sbin:$PATH"
which brew
brew env

[w3ntao]

I don't have a .bash_profile in ~ so gedit create a new one for me. Still: `$ which brew~ brew not found

[sjackman]

Please try:

PATH="$HOME/.linuxbrew/bin:$HOME/.linuxbrew/sbin:$PATH"
which brew
brew doctor

[w3ntao]

It works this time but not after starting a new terminal. So there is something wrong with .bashrc?

[w3ntao]

Found it, It's about zsh. I edit .zshrc and everything goes. I thought zsh would inherit config from bash

[w3ntao]

Thanks, @sjackman @rwhogg

[tseemann]

@sjackman @rwhogg We should probably check $SHELL to tell people which dotfile to add the PATH stuff to ?

[w3ntao]

@tseemann @sjackman @rwhogg I think you should.

[sjackman]

echo 'PATH="$HOME/.linuxbrew/bin:$HOME/.linuxbrew/sbin:$PATH"' >> ~/.$(basename $SHELL)rc
$SHELL -c 'brew doctor'

?

[tseemann]

@sjackman pretty much, maybe $HOME/.$(basename ${SHELL:-bash})rc for safety in case $SHELL was undefined... is ~ guaranteed to work in all shells?

[sjackman]

Yep, ~ expands to $HOME on pretty much ever shell that I know of. Only at the start of a word though, not in the middle, so the above $HOME can't be replaced by ~.

❯❯❯ echo ~
/Users/sjackman
❯❯❯ echo PATH=~
PATH=~
