macOS Ventura entraîne l'échec de l'installation de « mysql2 » en raison de « ld : bibliothèque introuvable pour -lzlib »

Question

Non disponible bundle install 安装 mysql2. Je pose cette question car certains sites Web et blogs ont montré comment résoudre les solutions causées par ssl、zstd 引起的问题，但我找不到由 zlib. Quelqu'un d'autre a-t-il rencontré le même problème ?

BTW, j'utilise bundle install localement, pas sur Docker.

• Système d'exploitation : Ventura(13.3.1)
• Xcode : 14.3
• Rubis : 3.1.4
• Rail : 6.1
• mysql2:0.5.5

Déjà terminé :

• brew 安装 mysql、openssl@3、zstd、zlib

An error occurred while installing mysql2 (0.5.5), and Bundler cannot continue.

In Gemfile:
  mysql2

Ce que j'ai essayé

・Exécution brew install zlib 后，将以下内容添加到 .zshrc

export LDFLAGS="-L/opt/homebrew/opt/zlib/lib"
export CPPFLAGS="-I/opt/homebrew/opt/zlib/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/zlib/lib/pkgconfig"

・Ajoutez les éléments suivants, qui ne sont pas affichés dans brew info zlib mais sont mentionnés dans les réponses ici.

export DYLD_LIBRARY_PATH=/opt/homebrew/opt/zlib/lib:$DYLD_LIBRARY_PATH

·Réinstaller命令行工具 by xcode-select --install

Résultat :

• Il n'y a aucun changement dans le journal de sortie.
• Ne peut pas être regroupé et installé mysql2

Answer 1

La solution proposée par Fyorden a fonctionné pour moi, mais dans mon cas, elles ont été installées par homebrew, donc elles étaient dans des chemins différents. J'ai édité le fichier dans le projet racine .bundle/config en utilisant les paramètres :

BUNDLE_BUILD__MYSQL2: "--with-mysql-lib=/opt/homebrew/opt/mysql/lib --with-mysql-dir=/opt/homebrew/opt/mysql --with-mysql-config=/opt/homebrew/opt/mysql/bin/mysql_config \ --with-mysql-include=/opt/homebrew/opt/mysql/include --with-ldflags=-L/opt/homebrew/opt/zlib/lib"

Answer 2

Bonjour, pour corriger la même erreur, j'ai créé un fichier sur le projet racine : .bundle/config avec ce paramètre

---
BUNDLE_BUILD__MYSQL2: "--with-mysql-lib=/usr/local/opt/mysql/lib --with-mysql-dir=/usr/local/opt/mysql --with-mysql-config=/usr/local/opt/mysql/bin/mysql_config \ --with-mysql-include=/usr/local/opt/mysql/include --with-ldflags=-L/usr/local/opt/zlib/lib"

Je pense qu'il s'agit d'un bug avec le dernier package MySQL Brew

Je me suis inspiré de https://prabinpoudel .com.np/notes/error-while-installing-mysql2-in-m1-mac/
