「gem install kindai」出来ず、rubygem アップデートとSSLの証明書エラーに困る。（解決済み）

Last updated at Posted at 2017-03-18

MacOSX 10.9
ruby 2.1.10p492　ー＞ruby 2.2.5p319
$ gem -v
2.4.5.1

国会図書館デジタルライブラリーダウンローダーをインストールしたい。
（国会図書館デジタルライブラリーの旧名は近代デジタルライブラリー）
GitHub - hitode909/kindairb: 近代デジタルライブラリーダウンローダ
https://github.com/hitode909/kindairb

１．gem install kindaiでエラーが起こり、SSLのエラーも対処できない。

$ gem install kindai
ERROR:  Could not find a valid gem 'kindai' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=error: certificate verify failed (https://api.rubygems.org/latest_specs.4.8.gz)

$ gem install kindai --source https://github.com/hitode909/kindairb
ERROR:  Could not find a valid gem 'kindai' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=error: certificate verify failed (https://api.rubygems.org/latest_specs.4.8.gz)
          Unable to download data from https://github.com/hitode909/kindairb/ - bad response Not Found 404 (https://github.com/hitode909/kindairb/latest_specs.4.8.gz)

２．gem をアップデートしてもSSLエラー

SSL Certificate Update - RubyGems Guides
http://guides.rubygems.org/ssl-certificate-update/#installing-using-update-packages

gem をアップデートする必要があるらしい。
普通にアップデートしてもSSLエラー

$sudo gem update --system
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    SSL_connect returned=1 errno=0 state=error

３．rubygemインストールに成功

SSL Certificate Update - RubyGems Guides
http://guides.rubygems.org/ssl-certificate-update/#installing-using-update-packages
によれば、以下のとおりらしい。

[C:>gem install --local C:\rubygems-update-2.6.11.gem]

解凍したディレクトリには、rubygems-update-2.6.11.gemは存在しないので

$ sudo ruby ./setup.rb

を実行。gem2.6.11はインストールされる。

$ gem -v
2.6.11

４．証明書のインストールしてもSSLエラー

gem2.6.11インストールしても、何故かSSLエラー状況が変わらない。

参考
Windowsでgem installするとSSLエラーが出る場合の解決策 - Qiita
http://qiita.com/shimoju/items/394818b4989b94680aaf

SSL Certificate Update - RubyGems Guides
http://guides.rubygems.org/ssl-certificate-update/#installing-using-update-packages
上記URLの「Manual solution to SSL issue」を参考に証明書のインストール。

[homedir]/.rbenv/versions/2.1.10/lib/ruby/2.1.0/rubygems/ssl_certs/
に、AddTrustExternalCARoot-2048.pemをコピー。

.pemをコピーしても、何故かSSLエラー状況が変わらない。

５．SSLのエラーがまだ続く。

ログに「expired at 2014-01-28T12:00:00Z」とあるので、未だに古い証明書を参照している模様。
ログにファイル名もないので、どのpemを参照してエラーになっているか分からない。
rubygem公式ではSSLの証明書ファイルである.pemを更新しろ、と書かれているが
厳密な手順ではなく、間違っているのではないだろうか？
今の所、SSLを差し替える方法はお手上げ。

$ gem install kindai
ERROR:  SSL verification error at depth 2: certificate has expired (10)
ERROR:  Certificate /C=BE/O=GlobalSign nv-sa/OU=Root CA/CN=GlobalSign Root CA expired at 2014-01-28T12:00:00Z
ERROR:  SSL verification error at depth 2: certificate has expired (10)
ERROR:  Certificate /C=BE/O=GlobalSign nv-sa/OU=Root CA/CN=GlobalSign Root CA expired at 2014-01-28T12:00:00Z
ERROR:  SSL verification error at depth 2: certificate has expired (10)
ERROR:  Certificate /C=BE/O=GlobalSign nv-sa/OU=Root CA/CN=GlobalSign Root CA expired at 2014-01-28T12:00:00Z
ERROR:  Could not find a valid gem 'kindai' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=error: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)
ERROR:  SSL verification error at depth 2: certificate has expired (10)
ERROR:  Certificate /C=BE/O=GlobalSign nv-sa/OU=Root CA/CN=GlobalSign Root CA expired at 2014-01-28T12:00:00Z

６．pemファイルを検索、grep

$ find / -name \*.pem -print0 | xargs -0 ggrep --color 2014
/Users/xxxxxxxx/source/curl-7.47.1/tests/stunnel.pem:            Not Before: Feb 22 15:38:48 2014 GMT

一つだけ見つかるが、お手上げ。

ruby 2.1.10p492をアンインストールして、最近のrubyをインストールするしかないか？

７．rubyのバージョンを上げるとSSLは解決

rbenvでrubyのバージョンを上げた。

$ ruby -v
ruby 2.2.5p319 (2016-04-26 revision 54774) [x86_64-darwin13]

$ gem -v
2.4.5.1

するとSSLの問題は解決した。
わけもわからず、ruby 2.2.5p319にしてしまった。
ruby2.2.5p319が2.2.5の最終版であることぐらいしか認識がない。

SSLの問題が無くなったが、今度はkindaiインスト時のRMagickインストールエラー。

$ gem install kindai
Building native extensions.  This could take a while...
ERROR:  Error installing kindai:

８．gem install rmagick でインストール失敗

次の問題が発生した。(笑)

gem install rmagick でインストール失敗 - Qiita
http://qiita.com/tajihiro/items/3f10c59f19fcd0a9e660

homebrewでインストールすると失敗するらしい。
imagemagickインスト時の　./configureのオプションの問題だろうか？

参考：homebrewバージョン７のオプションはこんな感じらしい
（==> ./configure --disable-osx-universal-binary --prefix=/usr/local/Cellar/imagemagick/7.0.5-2 --disable-silent-rules --enable-shared --enable-static --with-modules --disable-opencl --disable-openmp --without-webp --without-openjp2 --without-gslib --with-gs-font-dir=/usr/local/share/ghostscript/fonts --without-fftw --without-pango --without-x --with-freetype=yes）

９．「imagemagickのバージョンを７ではなく６にする」とgem install rmagick でインストール可能に

bundle install "rmagick" でインストールができない - Qiita
http://qiita.com/sho012b/items/362abe993248c686fcf4#_reference-4aa90991b151d5e21d84

imagemagickのバージョンを７ではなく６にする必要があるらしい。

$ brew install imagemagick@6

$ brew link --force imagemagick@6

１０．gem install kindaiのインストールエラーまでたどり着いた。

また、次の問題が発生した。(笑)

$ gem install kindai

************************************************************************
IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.4.

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries
    bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

$

行うべき対処方法が書かれているにもかかわらず、これくらい長いエラーログだと
事例がない場合、自分だけでは１１番の対処が難しい。

上から順に推測できるのは次の通り。
推測
１．Nokogiriインストール結果がエラーかワーニングか謎。
２．Running 'compile' for libxml2 2.9.4... ERRORなのでlibxml2に着目すべき？
３．xmlIO.c:1450:52: error: use of undeclared identifier 'LZMA_OK'
xmlIO.cエラーが根本原因なら全くのお手上げ。

１１．「nokogiri」のインストエラーに対処。

kindaiのインストールエラーではなく「nokogiri」のインストエラー。

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.

macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/libxml2/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/libxml2/lib
    CPPFLAGS: -I/usr/local/opt/libxml2/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/libxml2/lib/pkgconfig
