我最近运行了更新:

gem update --system
gem update

现在,每次加载gem时,我都会带着许多的警告。例如,rails console:

NOTE: Gem::Specification#default_executable= is deprecated with no replacement. It will be removed on or after 2011-10-01.
Gem::Specification#default_executable= called from /Users/user/.rvm/gems/ruby-1.9.2-p180@global/specifications/rake-0.8.7.gemspec:10.

Loading development environment (Rails 3.0.7)
ruby-1.9.2-p180 :001 > exit

我使用RVM、Rubygems 1.9.2和Rubygems 1.8.1。有办法解决这个问题吗?

我已经气炸了,我甚至退回到了1.6.2。它们使最新版本完全无法使用。确实应该有一种方法来禁用它们,但在此之前:

sudo gem update --system 1.6.2

跑一下:

gem pristine --all --no-extensions

ruby -e "`gem -v 2>&1 | grep called | sed -r -e 's#^.*specifications/##' -e 's/-[0-9].*$//'`.split.each {|x| `gem pristine #{x} -- --build-arg`}"

如果不行就这个:

ruby -e "%x(gem -v 2>&1 | grep called | sed -r -e 's#^.*specifications/##' -e 's/-[0-9].*$//').split.each {|x| %x(gem pristine #{x} -- --build-arg)}"
