我在苹果 M1 mac os 12.1 我已经用命令成功安装了mysql2

gem install mysql2 -v '0.5.3' -- \
--with-mysql-lib=/opt/homebrew/Cellar/mysql/8.0.28/lib \
--with-mysql-dir=/opt/homebrew/Cellar/mysql/8.0.28 \
--with-mysql-config=/opt/homebrew/Cellar/mysql/8.0.28/bin/mysql_config \
--with-mysql-include=/opt/homebrew/Cellar/mysql/8.0.28/include

Successfully installed mysql2-0.5.3
Parsing documentation for mysql2-0.5.3
Done installing documentation for mysql2 after 0 seconds
1 gem installed

当运行 bundle install 时我仍然收到错误

linking shared-object mysql2/mysql2.bundle
ld: warning: directory not found for option '-L/opt/homebrew/Cellar/mysql/8.0.28/lib --with-mysql-dir=/opt/homebrew/Cellar/mysql/8.0.28

ld: library not found for -lzstd
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [mysql2.bundle] Error 1

安装 mysql2 (0.5.3) 时出错，Bundler 无法继续。在捆绑之前确保gem install mysql2 -v '0.5.3' 成功。

我在使用 M1 mac 时遇到了同样的错误，并尝试了以下这些命令。

$ brew install openssl
$ echo 'export PATH="/opt/homebrew/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc
$ source ~/.zshrc
$ bundle config --local build.mysql2 "--with-ldflags=-L/opt/homebrew/opt/openssl@1.1/lib"
$ export LIBRARY_PATH=$LIBRARY_PATH:/opt/homebrew/Cellar/zstd/1.5.2/lib:/opt/homebrew/Cellar/openssl@1.1/1.1.1m/lib/
