Gemのアップデート
Debian環境でgemを最新版にアップデートしようとすると、
$ sudo gem install -update
ERROR: While executing gem ... (OptionParser::InvalidArgument)
invalid argument: -pdate
$ sudo gem update --system
ERROR: While executing gem ... (RuntimeError)
gem update --system is disabled on Debian, because it will overwrite the con
tent of the rubygems Debian package, and might break your Debian system in subtle ways. The Debian-supported way to update rubygems is through apt-get, using Debian official repositories.
If you really know what you are doing, you can still update rubygems by setting the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this is completely unsupported by Debian.
という感じに怒られてしまいますので、その際の対処法をメモしておきたいと思います。
