ruby-install's Issues

ruby >= 2.0 requires systemtap headers

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

Support skipping the package manager entirely

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

Do not hard code the path to brew

Homebrew can be installed anywhere. Personally, I have it installed in ~/.homebrew; consequently, ruby-install fails since it's looking for brew in /usr/local/bin/brew.

rubinius fails to compile

I am unable to compile rubinius through ruby-install. Works fine outside of it.

Compiling rubinius 2.0.0-rc1 ...
GEN vm/gen/config_variables.h
/Users/bgoff/.rvm/rubies/rbx-head/bin/rbx vm/codegen/config_vars.rb vm/gen/config_variables.h
An exception occurred running vm/codegen/config_vars.rb
undefined method `map' on nil:NilClass. (NoMethodError)

Not sure if this is because of the build that is being downloaded or what

Rubygems (gem) not installed for ruby 1.8.7

After installing 1.8.7 on my OSX (10.8.4) machine it appears that rubygems is not installed.

It then uses the system gem command:

gem env returns the following:

RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.6
  - RUBY VERSION: 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]

  - REMOTE SOURCES:

     - http://private.gems.openminds.be

I guess you don't need it, but I'm using chruby to manage my ruby versions.

Warn users that ruby 1.8.x is EOLed?

As suggested by @mpapis, should we print a warning message to users that ruby 1.8.x is no longer maintained?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.

www.ruby-lang.org does not support byte-ranges, so resuming downloads do not work

Add files for installing maglev

We should also try to support installing maglev.

Problem with applying patches to a ruby

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.

Improve fetch() to strip '\t' whitespace

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

Support skipping download and use an existing archive

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

Handle Mountain Lion/Ruby 2.0/OpenSSL debacle

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.

Fallback to curl if wget isn't available

Support downloading archives using curl, if wget isn't available.

Add files to build mruby

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.

Add a man-page for ruby-install

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

Support downloading from an alternate URL

Allow downloading from an alternate URL.

Add getopt option parsing

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.

pacman -Sy is a Bad Idea

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.

Add md5 or sha1 checksums

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.

Space in directory being read as argument.

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.

Support Rubinius >= 2.0.0

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.

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.

Flag to disable docs generation.

Add --rubies-dir option

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

parallel make of 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.

Can't continue installation when file already exists

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.
!!! Download of https://github.com/rubinius/rubinius/archive/release-2.0.0-rc1.tar.gz failed!

Add option to remove 'ruby-' prefix

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.

Add files to install topaz ruby

We should also try to support install topaz ruby.

Support binary builds (like RVM does)

That would be a killer feature.

ruby-install symlink in ~/bin

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.

Add pacman dependencies for rubinius

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

`yum updateinfo` is not available in CentOS vanilla installations

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.

`ruby-install rubinius 2.0.0-rc1` doesn't work with Ruby 2.0.0

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.

install of 1.9.4-p448 failing in weird ways

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

Huh?

Ruby installs directly into $INSTALL_DIR

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

Allow installing precompiled binary packages

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

installing jruby-1.7.4 fails

Environment:

• 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:

When to drop support for building Ruby 1.8

How long should we continue supporting building Ruby 1.8?

Rubinius 2.0.0 final is out.

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

Add option to skip installation

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

BSD `stat` and GNU `stat` take different options

When installing any ruby, I get:

This is because BSD stat (default on Darwin) takes a -f "%Su" option, while GNU coreutils stat uses -c "%u"

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

associative arrays are not supported by bash 3.2

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?

Rubinius 2.0

Now is a good time to fully support Rubinius.
