Ruby 3.2 から libyaml や libffi などのソースコードがバンドルされなくなった*1らしく、その影響で次のようなエラーが出た。どうやら libyaml が見つからないらしい。
$ rbenv install --verbose 3.2.0 (snip) yaml.h not found (snip) psych: Could not be configured. It will not be installed. Check ext/psych/mkmf.log for more details. *** Fix the problems, then remove these directories and try again if you want. Generating RDoc documentation /private/var/folders/jr/yc04bj413qscqvvgr4b31j7w0000gn/T/ruby-build.20230106185644.21896.yeUJhx/ruby-3.2.0/lib/yaml.rb:3: warning: It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. uh-oh! RDoc had a problem: cannot load such file -- psych (snip)
結論から言えば、次のようにしたら通った。
$ brew install libyaml $ brew link libyaml $ export LDFLAGS="-L/opt/homebrew/lib $LDFLAGS" $ export CFLAGS="-I/opt/homebrew/include $CFLAGS" $ rbenv install 3.2.0
以下、雑多なメモ。
背景としては二つの要因があって、
- 僕の環境では ruby-build 向けに
RUBY_CONFIGURE_OPTS="--with-yaml-dir=$(brew --prefix libyaml)"みたいに設定してあって、 libyaml のパスが ruby の./configureに渡されるようにしてあった。しかし、いつからかこの configure オプション自体が消えたため、 libyaml のパスが渡されなくなっていた - Intel Mac 時代の homebrew は brew link すれば /usr/local/lib や /usr/local/include にライブラリをリンクしてくれていたので、^のオプションがなかったとしてもコンパイラのデフォルト設定で見つかっていた。しかし、 M1 Mac からは brew link しても /opt/homebrew/lib や /opt/homebrew/include にリンクされるだけで /usr/local 配下には入らないので、コンパイラが見つけることができなくなった
- なので、 LDFLAGS や CLAGS を使って libyaml などのライブラリがある場所を指定する必要が出てきた
ということなんだと思う。低レイヤについては詳しくないので間違っているかもしれない。
ついでに、 ruby 3.2.0 の configure オプションの一覧もメモしておく。
$ ./configure --help
`configure' configures this package to adapt to many kinds of systems.
Usage: ./configure [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print `checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for `--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or `..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc. You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.
For better control, use the options below.

--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
