Hi @michael! You're probably missing a system dependency. If you're on mac, can you try

$ brew install openssl
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

$ meltano add loader target-postgres --variant meltano

Hi @edgar_ramirez_mondragon, thanks for your quick reply. Yes i am on a mac and i tried what you mentioned, but it is still the same: ➜ test meltano add loader target-postgres --variant meltano 2022-01-27T072811.914768Z [info ] ascii passed initial chaos probing.
