无法在macOS Sierra上使用rbenv和ruby-build构建Ruby 2.5.0

Question

I tried to install ruby 2.5.0 with rbenv and ruby-build on macOS Sierra, but it failed and I got error messages as below:

$ rbenv install 2.5.0

I checked the log files and found the error below:

                          ~~~~~~~~~~~~~~~~~~~~~~~~~~  ^

I have no idea why this error happens. I would appreciate it if you would explain how to solve this problem.

After then, I tried to rbenv install 2.5.0 with gcc provided by Xcode on macOS High Sierra, and same problem happened.

Answer 1

It works for me on the same OS. An issue in ruby-build that produced this error was reported and fixed recently.

Update rbenv and ruby-build

• If you're getting them from git:

   cd ~/.rbenv git pull cd plugins/ruby-build git pull 

• If you're getting them from homebrew:

   brew update brew upgrade rbenv ruby-build 

and try rbenv install 2.5.0 again.

If you're using rbenv & ruby-build homebrew, you could try using them from git.

I finally fixed this problem. When this problem happened, my rbenv treid to install ruby 2.5.0 using openssl-1.1.0g. This openssl was selected by rbenv and ruby-build. In my environment, I installed openssl@1.0.2n_0 by MacPort. I selected this openssl to installing ruby 2.5.0 with rbenv and ruby-build.

$ rbenv versions
  system
* 2.4.0 
$ port installed | grep openssl
  openssl @1.0.2n_0 (active)
$ RUBY_CONFIGURE_OPTS="--with-openssl-dir=/opt/local --with-gdbm-dir=/opt/local"  rbenv install -v 2.5.0
$ rbenv versions
  system
* 2.4.0 
  2.5.0

When I did not use --with-gdbm-dir=/opt/local , I got the below message:

*** Following extensions are not compiled:
gdbm:
    Could not be configured. It will not be installed.
    Check ext/gdbm/mkmf.log for more details.
*** Fix the problems, then remove these directories and try again if you want.

用它来安装rbenv的ruby最新版本

RUBY_CONFIGURE_OPTS="--disable-dtrace" rbenv install 2.5.1
