Ruby-build: Cannot install ruby on macOS 10.14.4

[stevetoro]

Edit: To clarify, this is happening with all versions of Ruby that I try to install with rbenv.

I'm trying to install ruby 2.6.4 with rbenv 1.1.2. Machine is macOS Mojave.

The command rbenv install 2.6.4 just hangs after reaching ruby-build: using readline from homebrew.

From other threads, I've tried running RUBY_CONFIGURE_OPTS=--with-readline-dir="$(brew --prefix readline)" rbenv install 2.6.4 as well as disabling (uninstalling) my antivirus software. Uninstalling and reinstalling brew, rbenv, ruby-build, readline, etc. Same result.

Here's the log:

I'm also experiencing this issue

Hit the same issue, and when I run rbenv install --list there is no 2.6.4–or 2.6.3 for that matter–the latest in the 2.6.x series is 2.6.2.

@armcknight you probably need to update ruby-build. Latest is 20191111.

I've been trying to get this installed for the last few hours on a new iMac with 10.15.6. Fresh install of homebrew and keeps hanging in the same spot config.status: creating Makefile.

I've had readline give me issues in the past on but all the tricks I used to use haven't worked.

Hello I ran into the same exact issue. This is what fixed it for me:

Catalina XCode command line tools no longer has SVN, and at that specific part of the installation, it relies on SVN being installed on your computer, so it gets stuck there if your computer is missing it.

so basically, running this:
brew install svn

and then trying again, resolved everything for me

@kwuuu THANK YOU!
The little things we take for granted sometimes, like SVN just being there.

[ShanaSkydancer]

@kwuuu This fixed it for me!
Thank you so much!

gives you a virtual coffee and high five

Just as an update, this continues to happen on macOS 10.15.7 with rbenv 1.1.2 and ruby-build 20201210.

rbenv install -v 2.7.2 shows the command hanging at checking whether make sets $(MAKE)... make: *** No targets specified and no makefile found. Stop.

I've tried uninstalling homebrew, rbenv, make, etc. rvm is completely removed.
