我 运行 'bundle install' 并且发生了这个错误。
所以为了修复项目的错误，我在控制台中 运行 'gem install mysql2 '0.4.8'' 命令但我无法修复它。
rails 上的 ruby 使用 Spree 框架。
编辑：

我 运行 'bundle install' 但由于这个错误我无法成功执行此命令。
我想你缺少 mysql 的开发库：
上ubuntu
sudo apt-get install libmysqlclient-dev
On Red Hat/CentOS 和其他使用 yum 的发行版：
sudo yum install mysql-devel
在 Mac OS X 上使用 Homebrew:
brew install mysql
我遇到了类似的问题，但对于 v4.10
Error occurred while installing mysql2 (0.4.10), and Bundler cannot continue
所以我不得不运行以下命令来解决上述问题。
sudo apt-get update
sudo apt-get install build-essential
对于 Mac，我遇到了 openssl issue
An error occurred while installing mysql2 (0.5.2), and Bundler cannot continue.
我使用如下命令解决了这个问题；
$ bundle config --local build.mysql2 "--with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include"
$ sudo bundle install

替代解决方案
if you still have error and got the message in the console that: You are replacing the current
local value of build.mysql2, which is currently nil. Please try as below:
$ export LDFLAGS="-L/usr/local/opt/openssl/lib"
$ export CPPFLAGS="-I/usr/local/opt/openssl/include"
然后运行:
$ sudo gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/' -- --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib
显示结果：
Building native extensions with: '--with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib'
This could take a while...

最后，运行 在您的项目中安装包：
$ sudo bundle install
让我知道它是否可以拯救你的一天！！！ :)
如果您使用 mac，请确保先安装 openSSL。
brew install openssl
然后导出
$ export LDFLAGS="-L/usr/local/opt/openssl/lib"
$ export CPPFLAGS="-I/usr/local/opt/openssl/include"
确保您已安装 mysql
gem install mysql2 -v '0.5.3' \
--source 'https://rubygems.org/' -- \
--with-cppflags=-I/usr/local/opt/openssl/include \
--with-ldflags=-L/usr/local/opt/openssl/lib
然后运行捆绑
bundle install
我的头发几乎掉光了，因为我买了一个新的 machine，我不记得我必须安装 openssl。
Ubuntu 18
您可能需要安装
sudo apt-get install libssl-dev
如 This 答案
MacOS 蒙特雷 (M1)
lib 和 include 文件的位置在 Homebrew 中已更改。我使用 this guidance 设置了正确的安装路径。
我首先使用此 procedure 刷新我的 Ruby 和 Rails 安装。这将安装 openssl 依赖项。
$ export LIBRARY_PATH=$LIBRARY_PATH:$(brew --prefix openssl@1.1)/lib/
仔细检查我的 mysql 安装后，我遇到了最后一个障碍，zstd 阻止了构建。我使用（归功于 ）修复了此问题：
bundle config --local build.mysql2 \
"--with-ldflags=-L/opt/homebrew/Cellar/zstd/1.5.0/lib"
您现在已阅读 运行 再次打包
bundle install
我找到了 mysql 的路径，它是通过自制软件和 运行 以下命令安装的：
gem install mysql2 -- \
--with-mysql-lib=/opt/homebrew/Cellar/mysql/8.0.27/lib \
--with-mysql-dir=/opt/homebrew/Cellar/mysql/8.0.27 \
--with-mysql-config=/opt/homebrew/Cellar/mysql/8.0.27/bin/mysql_config \
--with-mysql-include=/opt/homebrew/Cellar/mysql/8.0.27/include
替换 mysql 的路径，应该可以解决问题。
对于使用macOS Monterey（M1Pro/Max）的人，我找到了一个简单快速的解决方案：
复制并粘贴到您的终端
arch -x86_64 gem install mysql2 -v 0.5.3 -- --srcdir=/usr/local/mysql/include
现在您可以 运行 bundle 而不会出现任何 MySql 错误
也使用 macOS Monterey，这对我有用：
gem install mysql2 -- --srcdir=/usr/local/mysql/include
