rails new fails with 'couldn't set additional authenticated data' on macos

Question

I'm trying to get ruby on rails working on a new Mac with an M1 chip. Running rails new fails after append .gitignore with the following error

/Library/Ruby/Gems/2.6.0/gems/activesupport-6.0.3/lib/active_support/message_encryptor.rb:173:in `auth_data=': couldn't set additional authenticated data (OpenSSL::Cipher::CipherError)

• MacOS version: 12.3.1 Monterey, Chip: Apple M1 Max
• Ruby version: 2.6.8p205 (2021-07-07 revision 67951) [universal.arm64e-darwin21]
• Rails version: 6.0.3
• Node version: 14.19.0
• Yarn version: 1.22.18

Has anyone else run into this? My rage-googling hasn't come up with much of anything on this one

Answer 1

Instead of using system ruby, I would suggest using rbenv to install gems to avoid version conflicts. Then you can use export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix [email protected])" to set the correct SSL version
