If you attempt to install rubinius 2.0.0-rc1 with Ruby 2.0.0 as active Ruby, you'll get a weird error:

undefined method `name' for -2.0000000000407714:Float

Even though this is Rubinius-bug, it would be nice if ruby-install would warn that you need Ruby 1.9.3.

http://cl.ly/image/1K2s1F1w1r3E

We should also try to support install topaz ruby.

It would be nice if ruby-install could do a parallel make of Ruby, according to the cpu core count. I haven't found an "official" statement as to whether Ruby's makefile really supports parallel make, though.

I have tried to install Rubinius which failed due to some weird segfault (possibly my old hardware). When I tried another install I got the following error:

$ sudo ruby-install rubinius

In order to fix this I have to manually remove the Rubinius files from /usr/local/src and then start sudo ruby-install rubinius again.

On a fresh CentOS 6.4 installation, the updateinfo subcommand ran in the pre install stage is not available, but requires the installation of the yum-security (aka yum-plugin-security) package.
I don't know if this holds even in Fedora.

An option I see here is to allow for installation of the missing package before running it.
Another option is to document this thing and let the user satisfy the prerequisites.

If you want, I can take care of making a PR for solving it.

Add support for checksuming the downloaded Ruby archives. Checksums should be stored in an checksums.txt file. If there is no checksum for the archive, print a warning and continue. If the checksum does not match the archive, print and error and return.

As suggested by @mpapis, should we print a warning message to users that ruby 1.8.x is no longer maintained? Since the default version for Ruby is 2.0.0, a user would have to explicitly specify they want 1.8.

Currently this doesn't work because it looks for ~/share (which I don't want to put there).

Solvable by replacing $0 with $(readlink -f $0) in line 5 of ruby-install.

Can't see how it would break any (sane) existing use cases.

Hi,

I worked up what I thought would be a cool labor saving tip to applying a bunch of patches to a ruby for this repo's wiki..

https://github.com/postmodern/ruby-install/wiki/Tip:-Apply-many-patches-to-MRI-source-one-liner

Only problem is, after applying a particular group of patches, configure blows up when creating the Makefile:

https://gist.github.com/zhando/5941699

This ruby, 1.9.3-p385 builds fine for vanilla ruby-install (no patches).. It works fine for my ruby-build "recipe" which includes all of those very same patches.

Something glitches however when you use bash parameter substitution to specify a group of patches to ruby-install - for this particular ruby anyway.. The patches all seem to apply cleanly..

Try it.. I'm curious to know what you all think.

Here's the output I'm getting:

https://gist.github.com/myronmarston/6699131

Any ideas how to fix this?

Add a markdown man-page for ruby-install and use md2man to compile it into roff. See chruby Makefile for an example.

Associative arrays (declare -A) were added in version 4.0 of bash and are used in ruby-install.

Better to make bash 4.0+ a requirement of ruby-install or backbend around not having associative arrays in order to support bash 3.2?

Support an --md5 option, in case we don't have the md5 for a newer version.

But per #54, trying to run sudo probably isn't the answer either. What's going on?

Add an option to only extract/configure/build the Ruby, but not install it.

Allow downloading from an alternate URL.

https://github.com/postmodern/ruby-install/blob/master/share/ruby-install/ruby-install.sh#L97

It's well known[1] in the Arch world that pacman -Sy foo can break your system. Users are advised never to update the index without also updating the system.

pacman -Sy; pacman -S foo is just a variation on that. I suggest you leave the index un-updated and just install the dep by name at whatever version the current index specifies.

1: https://bbs.archlinux.org/viewtopic.php?id=89328

This is just one example thread I could find. There's some back and forth, but Allan spells out the issue clearly in a few replies, and he's a core pacman dev / Arch maintainer.

Should be able to skip downloading the archive, and use an existing one.

Now is a good time to fully support Rubinius.

http://rubini.us/2013/10/04/rubinius-2-0-released/

Great work on ruby-install!

I used it to install Ruby 2.0, but lost some time dealing with Ruby 2.0's handling of OpenSSL. Ruby 2.0 refuses to use Mountain Lion's crippled version, and Homebrew does not symlink the updated version. Users installing Ruby 2.0 on OS X need to do the following:

$ brew install openssl
$ ruby-install ruby 2.0 -- --with-openssl-dir=`brew --prefix openssl`

What makes this confusing is that configure incorrectly reports that the option is unknown, but then goes ahead and uses it. I think ruby-install should help out here. Rubies without OpenSSL support will have a hard time pulling gems down, so they're pretty much DOA for most users.

One suggestion: ruby-install could look for probe for an updated OpenSSL:

$ brew --prefix openssl

And pass that to configure for MRI 2.x on OS X.

Add an option to allow skipping syncing the package manager or installing packages from it.

Oh, yeah, it would be nice if the src directory was under the .rubies directory.

• Ubuntu 13.10 Saucy Salamander x86_64
• rbenv 0.4.0-65-gff23666 (latest)
• ruby-install 463e15b (latest)

I installed ruby 2.1.0-preview1 without problems. Instead, attempting to install jruby-1.7.4 installation fails with the following error:

I'm trying to install ruby in a specific directory and the directory name has a space in it. So when I run the command.....

$ ruby-install -i /this directory/here ruby 1.9.3

OR

$ ruby-install -i /this\ directory/here ruby 1.9.3

I get this

ruby-install: too many arguments: directory/here ruby 1.9.3

It looks like after the space, the rest of the directory is being read as an argument.

Need to parse the following options:

• --src-dir DIR
• --install-dir DIR
• --patch FILE
• --skip-sync
• --skip-dependencies (implies --skip-sync)
• --skip-verify

Any additional options (after the -- separator) will be treated as ./configure options.

Add a --rubies-dir option, which controls the prefix of the install directory (ex: --rubies-dir /opt/rubies/ or --rubies-dir ~/.rubies/).

Add an option to remove the 'ruby-' prefix from the Ruby name. For example, ruby-2.0.0-p195 would become 2.0.0-p195.

Setting a custom install dir with the -i flag installs the ruby files directly into that directory. eg.

ruby-install -i /usr/local/opt/rubies ruby 2.0.0-p0
ls /usr/local/opt/rubies
# bin include lib share

The expected result, based on the README, is:

ruby-install -i /usr/local/opt/rubies ruby 2.0.0-p0
ls /usr/local/opt/rubies
# ruby-2.0.0-p0

I think the fix is something to do with this, and that $RUBY-$RUBY_VERSION should be specified outside of the ${...} thing? I'm not entirely sure. 😕

# share/ruby-install/functions.sh
if [[ $UID -eq 0 ]]; then
    SRC_DIR="${SRC_DIR:-/usr/local/src}"
    INSTALL_DIR="${INSTALL_DIR:-/opt/rubies/$RUBY-$RUBY_VERSION}"
else
    SRC_DIR="${SRC_DIR:-$HOME/src}"
    INSTALL_DIR="${INSTALL_DIR:-$HOME/.rubies/$RUBY-$RUBY_VERSION}"
fi

Rubinius is missing the Arch package names for pacman. https://github.com/postmodern/ruby-install/blob/master/share/ruby-install/rubinius/dependencies.txt#L1

We should also try to support installing maglev.

According to the docs, I can get the latest 1.9 mri with ruby-install ruby 1.9

But that results in this:

$ ruby-install ruby 1.9
grep: brackets ([ ]) not balanced
>>> Installing ruby 1.9:    1.9.3-p448 into /Users/jrochkind/.rubies/ruby-1.9:    1.9.3-p448 ...
>>> Installing dependencies for ruby 1.9:    1.9.3-p448 ...
Error: No available formula for brew:
!!! Installing dependencies failed!

Huh?

Add functions.sh, dependencies.txt and md5.txt for mruby. This may require us to change ruby-install to accommodate pulling down a git repo instead of downloading an archive.

That would be a killer feature.

Only support rubinius >= 2.0.0, dropping support for 2.0.0-rc1 and 1.2.4.

• Download from http://releases.rubini.us/rubinius-X.Y.Z.tar.bz2
• Install LLVM 3.1, 3.2 or 3.3
  • Rubinius'es configure defaults to 3.2, but will 3.1 work for older distros (ex: Ubuntu 12.04LTS)?
• Install Ruby >= 1.9.
  • Ready, Set, ... recommends Ruby 2.0, but can we get away with Ruby 1.9? Most distros now provide ruby 1.9 packages. Fedora, Arch, Gentoo and Mavarick offer ruby 2.0.
• Install Bundler
  • Do we install via the package manager or via rubygems?
• Run bundle install --gemfile="$SRC_DIR/$RUBY_SRC_DIR/Gemfile" in install_optional_deps or configure_ruby.

Before I start, is there any interest in a PR to fix this? Here's a fix to the same issue in another project: rtomayko/shocco#17

I cannot install it with ruby-install.. it points to the RC1 :(

But http://rubini.us/2013/10/04/rubinius-2-0-released/?utm_source=rubyweekly&utm_medium=email

Allow installing binary Rubies. JRuby and Rubinius both have binary packages. RVM provides precompiled versions of MRI. http://rvm.io/binaries/

Currently the fetch function can only strip whitespace. It needs to also strip\t characters.

How long should we continue supporting building Ruby 1.8?

ruby >= 2.0 supports dynamic probes using systemtap on Linux. The systemtap headers should be added to the dependencies.

When installing if the source files are already there ruby-install quits with:

curl: (33) HTTP server doesn't seem to support byte ranges. Cannot resume.
