无法使用 bundle install 安装 mysql2。 我这样问是因为有些网站和博客已经展示了如何解决由 ssl、zstd 引起的问题，但我找不到由 zlib 引起的解决方案。有其他人遇到同样的问题吗？

顺便说一句，我在本地运行 bundle install，而不是在 docker 上运行。

  • 操作系统：Ventura(13.3.1)
  • Xcode: 14.3
  • 红宝石：3.1.4
  • 导轨：6.1
  • mysql2：0.5.5

已经完成：

  • brew 安装 mysql、openssl@3、zstd、zlib

这是日志输出。

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

In Gemfile:
  mysql2

我尝试过的

・执行 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"

・添加以下内容，这些内容未在 brew info zlib 中显示，但在此处的答案中提到。

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

·重新安装命令行工具 by xcode-select --install

结果：

  • 输出日志没有变化。
  • 无法捆绑安装 mysql2

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"

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

我的灵感来自https://prabinpoudel .com.np/notes/error-while-installing-mysql2-in-m1-mac/
