macOS Ventura führt dazu, dass die Installation von „mysql2' aufgrund von „ld: Bibliothek für -lzlib nicht gefunden' fehlschlägt.

Question

Nicht verfügbar bundle install 安装 mysql2. Ich frage das, weil einige Websites und Blogs gezeigt haben, wie man durch ssl、zstd 引起的问题，但我找不到由 zlib verursachte Lösungen beheben kann. Hat jemand anderes das gleiche Problem festgestellt?

Übrigens, ich verwende bundle install lokal, nicht auf Docker.

• Betriebssystem: Ventura (13.3.1)
• Xcode: 14.3
• Ruby: 3.1.4
• Schiene: 6.1
• mysql2:0.5.5

Bereits abgeschlossen:

• brew 安装 mysql、openssl@3、zstd、zlib

Dies ist die Protokollausgabe.

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

In Gemfile:
  mysql2

Was ich versucht habe

・Ausführung 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"

・Fügen Sie Folgendes hinzu, das in brew info zlib nicht angezeigt wird, aber in den Antworten hier erwähnt wird.

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

·Neu installieren命令行工具 by xcode-select --install

Ergebnis:

• Es gibt keine Änderung im Ausgabeprotokoll.
• Kann nicht gebündelt und installiert werden mysql2

Answer 1

Fyorden 提出的解决方案对我有用，但就我而言，它们是由自制软件安装的，因此它们位于不同的路径中。我使用参数编辑了根项目 .bundle/config 中的文件：

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

您好，要纠正相同的错误，我已经在根项目上创建了一个文件：带有此参数的 .bundle/config

---
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"

我认为这是最后一个 mysql brew 包的错误
