Linuxbrew on IdeaPad Duet

apt で Ruby を入れた状態で Homebrew を入れようとすると

Error: No Homebrew ruby 2.6.3_2 available for aarch64 processors!

Error: Failed to install Homebrew Portable Ruby and cannot find another Ruby 2.6!

If there's no Homebrew Portable Ruby available for your processor:

- install Ruby 2.6 with your system package manager (or rbenv/ruby-build)

- make it first in your PATH

- try again

Failed during: /home/linuxbrew/.linuxbrew/bin/brew update --force

となる。apt で rbenv 入れてみたけど、 Arm の Ruby 2.6 はない模様

source から Ruby を install

code: sh

sudo apt install build-essential bison libffi-dev libgdbm-dev libgdbm-compat-dev\

libreadline-dev libssl-dev zlib1g-dev

tar xvzf ruby-2.6.6.tar.gz

./configure --prefix=$HOME/local

make -j7

make install

make は110秒くらいで終わった。

これでもう一度

code:sh

したらいけた。最新の Ruby 2.7 では失敗。

code: sh

mkdir ~/.linuxbrew/bin

ln -s ~/.linuxbrew/Homebrew/bin/brew ~/.linuxbrew/bin

eval $(~/.linuxbrew/bin/brew shellenv)
