Error Installing Homebrew - Brew Command Not Found

问题:

I've spent the bulk of my Friday trying to get the latest version of Ruby installed on my new MacBook Air (w/ Mountain Lion installed).

I have all the latest versions of XCode and command line tools. But I can't seem to get Homebrew to work! Here's a screenshot of where I keep getting stuck (I'm a new user, so can't embed this image).

As you can see I used the following to instal Homebrew:

ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go/install)" 

While there was a "warning" it seemed as though the installation worked:

Warning: /usr/local/bin is not in your PATH. ==> Installation successful! 

Despite that, when I try to run "brew doctor" I received the following:

-bash: brew: command not found 

Again, I'm trying to install homebrew, so i can instal the latest version of ruby -- I'm looking to learn to code in ruby, but kind of screwed if I can even get a development environment running! :)

Thanks for any help you can offer!

回答1:

The warning is telling you what is wrong. The problem is that brew is kept in /usr/local/bin

So, you can try /usr/local/bin/brew doctor

To fix it permanently alter your bash profile (.bashrc or .profile in your home directory) and add the following line:

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

Check XCode is installed or not.

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

回答3:

nano ~/.profile 

add these lines:

export PATH="$HOME/.linuxbrew/bin:$PATH" export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH" export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH" 

save the file:

Ctrl + X then Y then Enter

then render the changes:

source ~/.profile

This was just happening to me, but none of the suggestions above worked. I changed directories ("cd ~/tmp") and suddenly the command

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

worked for me. Prior to changing directories I had been in a directory that is a Git repository. Perhaps that was interfering with the ruby and Git commands in the Brew install script.

回答5:

You can run in terminal

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

then install https://github.com/robbyrussell/oh-my-zsh.

When those complate run i.e pico editor pico .zshrc and past those lines:

export PATH="$HOME/.linuxbrew/bin:$PATH" export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH" export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH" 

remember use brew doctor :)

回答6:

try this

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/linuxbrew/go/install)" 

回答7:

You can use this:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"  

to install homebrew.
