RailsのBundleインストール時にmysql2でエラーが出る

エラーは以下です。

-----
Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load
-----
-----
Setting libpath to /usr/local/Cellar/mysql/8.0.21_1/lib
-----
creating Makefile

current directory: /Users/user/.rbenv/versions/2.6.6/lib/ruby/gems/2.6.0/gems/mysql2-0.5.3/ext/mysql2
make "DESTDIR=" clean

current directory: /Users/user/.rbenv/versions/2.6.6/lib/ruby/gems/2.6.0/gems/mysql2-0.5.3/ext/mysql2
make "DESTDIR="
compiling client.c

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

make failed, exit code 2

Gem files will remain installed in /Users/user/.rbenv/versions/2.6.6/lib/ruby/gems/2.6.0/gems/mysql2-0.5.3 for inspection.

解決方法

以下でcinfigを設定してあげて下さい。

bundle config --local build.mysql2 "--with-ldflags=-L/usr/local/opt/openssl/lib"

そして再度bundle installしてあげて下さい。

bundle install
