Question

我正在尝试使用以下命令

使用jRuby安装rails

jruby -S gem install rails -v 3.0.6

但坚持错误：

JRuby limited openssl loaded. http://jruby.org/openssl
gem install jruby-openssl for full support.

任何人都可以帮我解决这个错误。

提前致谢。

Answer 1

我刚才遇到过这个问题，但问题出在rspec。试试这个：
jruby --1.9 -S gem install rails -v 3.0.6

这告诉jruby使用ruby 1.9解释器。

Answer 2

此错误已在JRuby 1.6.2中修复。

在命令行（Windows）上解决JRuby 1.6.1的问题：

set JRUBY_OPTS=--1.9
# in your specific case
gem install rails   

# this is where I got the error (Rails 3 with Bundler)
bundle update

Answer 3

您正在安装的某些版本的gem可能会发生此错误，但不会发生其他版本。这是因为YAML错误是由YAML文件中的date字段引起的，如this comment for bug 5581中所述。

例如，生物宝石版本1.4.2对我造成例外。

如何获取元数据的说明来自Shaving a YAML Yak，除了我用gzcat代替gunzip和less

gem fetch bio --version 1.4.2
tar xvf bio-1.4.2.gem
gunzip metadata.gz
less metadata | grep date
date: 2011-08-26 00:00:00.000000000 Z

YAML.load("date: 2011-08-26 00:00:00.000000000 Z") # Causes exception

而对于生物的1.4.1版

gem fetch bio --version 1.4.1
tar xvf bio-1.4.1.gem
gunzip metadata.gz
less metadata | grep date
date: 2010-10-22 00:00:00 +09:00

YAML.load("date: 2010-10-22 00:00:00 +09:00") # Doesn't cause an exception

这样做sudo jruby -S gem install bio --version 1.4.1对我有用。

如果你想要最新的和最好的，那么你可以获取宝石并修改其元数据，或者自己构建宝石，但上面对我来说是Good Enough™。
