Re-Installing Homebrew and Environment for High Sierra

Hello Everyone.

I used Apple Macbook Air privately from 2013 and setup environment for programming(Vim+Tmux+zplug+fzf). It is long time since I updated High Sierra from Yosemite(As you know, current newest OS version is Mojave), but I didn’t do environment by today.

However, because it is 2019, I will use it for programming but Homebrew was very slow(I don’t know why), I update/re-make them today. Then, I decribe installation memos.

Reinstalling Homebrew

At first, I executed uninstallation Homebrew following Reinstalling Homebrew(Japanese site).

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

As the result, installed packages were uninstalled at the same time.

Next is newest Homebrew version installation.

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

After that, I installed some packages via Homebrew.

  $ brew install zsh zplug tmux vim the_silver_searcher reattach-to-user-namespace

Actually, I have uploaded dotfiles and by cloning it, I finished settting up environment immediately.

Overriding Vim

To use newest vim via Homebrew, it is necessary to overriding vim.

However, there is one problem when overriding ’/usr/bin/vim’.

  $ sudo mv /usr/bin/vim /usr/bin/old_vim
  mv: rename /usr/bin/vim to /usr/bin/old_vim: Operation not permitted

The reason about error is SIP(System Integrity Protection), which is the security function implemented from El Captain. When checking the status, the command and result massage are below.

  $ csrutil status
  System Integrity Protection status: enabled.

The steps to turn off SIP are below in order to override vim.

Shutdown/Reboot the PC
Push Command+R when booting it to enter Recovery Mode
Click Utility->Terminal
Execute csrutil disable in terminal
Successful message is Successfully disabled System Integrity Protection. Please resart the machine for the changes to take effect.
Execute reboot in terminal

After that, previous command is available.

  $ sudo mv /usr/bin/vim /usr/bin/old_vim
  $ sudo ln /usr/local/Cellar/vim/<version>/bin/vim /usr/bin

My current version is 8.1.0650.

I hope this article is useful for you.
