jruby-head Python ... ArgumentError：格式錯誤的版本號字符串2.7.2+

Question

jruby-head version.rb @ /.rvm/rubies/jruby-head/lib/ruby/shared/rubygems/version.rb has the以下的正則表達式：

VERSION_PATTERN = '[0-9]+(\.[0-9a-zA-Z]+)*' # :nodoc: 

這VERSION_PATTERN沒有發現蟒蛇的版本，由於在末尾加上：

2.7.2+ 

我已經試過修改：

/.rvm/rubies/jruby-head/lib/ruby/shared/rubygems/version.rb 

行148：

VERSION_PATTERN = '[0-9]+(\.[0-9a-zA-Z]+)*\+?' # :nodoc: 

以匹配加分，但它不工作。我認爲我的正則表達式是錯誤的。

使用JRuby頭：

% ruby --version 
jruby 1.7.0.RC1 (1.9.3p203) 2012-09-26 4f2c44e on OpenJDK 64-Bit Server VM 1.6.0_24-b24 [linux-amd64] 


% env |grep JRUBY 
JRUBY_OPTS=-Xcext.enabled=true 

% rvm list 
rvm rubies 

=> jruby-head [ x86_64 ] 
ruby-1.9.2-p320 [ x86_64 ] 
* ruby-1.9.3-p194 [ x86_64 ] 

% python --version 
    Python 2.7.2+ 

% gem install therubyracer

Answer 1

therubyracer不使用JRuby兼容。
