Can't install gems because "undefined method `invoke_with_build_args' for nil:NilClass"
I found that although I already had openSSL installed I needed to brew upgrade ruby before it was recognized. Another maze of twisty little passages, all alike.
It looks like you need to install OpenSSL first.So try to install it:
$ brew install openssl
And then you need to recompile ruby with OpenSSL:
$ CONFIGURE_OPTS="--with-openssl-dir=
brew --prefix openssl" rbenv install 2.1.1-p76
When I checked my
rbenv localand
rbenv global they we different.
So I set
rbenv local 2.6.5and it resolved my issue
