brewがlinuxで使えるらしいのでやってみる

## brewのインストール
ここに書かれてるコマンドをターミナルで打つ
https://brew.sh/

```
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  To install Linuxbrew, paste at a terminal prompt:
    sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
```
linuxは`sh -c "$(curl -fsSL https//raw.githubusercon~~~`を打てばいい

```
$ sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
==> This script will install:
/home/linuxbrew/.linuxbrew/bin/brew
/home/linuxbrew/.linuxbrew/share/doc/homebrew
/home/linuxbrew/.linuxbrew/share/man/man1/brew.1

/home/linuxbrew/.linuxbrew/etc/bash_completion.d/brew
/home/ryicoh/.cache/Homebrew/
/home/linuxbrew/.linuxbrew/Homebrew

==> Homebrew has enabled anonymous aggregate formulae and cask analytics.
Read the analytics documentation (and how to opt-out) here:
  https://docs.brew.sh/Analytics.html

==> Homebrew is run entirely by unpaid volunteers. Please consider donating:

==> Next steps:
- Install the Linuxbrew dependencies if you have sudo access:
  Debian, Ubuntu, etc.
    sudo apt-get install build-essential
  Fedora, Red Hat, CentOS, etc.
    sudo yum groupinstall 'Development Tools'
  See http://linuxbrew.sh/#dependencies for more information.
- Add Linuxbrew to your ~/.profile by running
    echo 'eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)' >>~/.profile
- Add Linuxbrew to your PATH
    PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"
- We recommend that you install GCC by running:
    brew install gcc
- After modifying your shell profile, you may need to restart your session
  (logout and then log back in) if the brew command isn't found.
- Run `brew help` to get started
- Further documentation:
    https://docs.brew.sh
Warning: /home/linuxbrew/.linuxbrew/bin is not in your PATH.
```
