Ruby on railsインストール opensslでハマった話※Mac

Last updated at Posted at 2022-11-22

1.rbenvインストール

brew install rbenv
rbenv install 3.1.2

テスト用フォルダ作成

mkdir ~/ruby-test
cd ~/ruby-test

テストフォルダへruby反映

rbenv local 3.1.2
rbenv rehash  

反映確認

ruby -v

rails インストール※bundlerはインストール済み

gem install rails

しかし、、

ERROR:  While executing gem ... (Gem::Exception)
    OpenSSL is not available. Install OpenSSL and rebuild Ruby (preferred) or use non-HTTPS sources

opensslが利用できないとのことなので

brew link openssl --force

しかし、

Warning: Refusing to link macOS provided/shadowed software: openssl@3
If you need to have openssl@3 first in your PATH, run:
  echo 'export PATH="/usr/local/opt/openssl@3/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@3 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@3/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@3/include"

For pkg-config to find openssl@3 you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openssl@3/lib/pkgconfig"

言う通りに実行

echo 'export PATH="/usr/local/opt/openssl@3/bin:$PATH"' >> ~/.zshrc
export LDFLAGS="-L/usr/local/opt/openssl@3/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@3/include"
export PKG_CONFIG_PATH="/usr/local/opt/openssl@3/lib/pkgconfig"

再度実行するが変わらない。。

brew link openssl --force

  echo 'export PATH="/usr/local/opt/openssl@3/bin:$PATH"' >> ~/.zshrc

  export PKG_CONFIG_PATH="/usr/local/opt/openssl@3/lib/pkgconfig"

色々試したがわからなかったので、再度rubyインストール

rbenv install 3.1.2

別ディレクトリを作成

mkdir ruby-test2
cd ruby-test2

今度はディレクトリ指定ではなく、globalにしrailsインストール

rbenv global 3.1.2
gem install rails 

おっ!

原因は特定できていないけど、一旦これでテストアプリ開発しようと思います。
