问题描述
我正在尝试完全卸载 Rails，但我无法控制它.
I’m trying to uninstall Rails completely, but I can’t get the grip of it.
这是我尝试过的:
$ gem update
rails 4.0.0.beta1 installed
$ rails -v
Rails 4.0.0.beta1
$ gem uninstall rails -v 4.0.0.beta1
但仍然:
$ rails -v
Rails 4.0.0.beta1
我如何才能完全删除 rails 版本?
How I can completely remove rails version ?
推荐答案
最终解决方案
只需卸载 railties -v 4.0.0，一切都很好.
$ which rails
~/software/bin/rails
$ rails -v
Rails 4.0.0
$ gem list | grep rails
rails (4.0.0, 3.2.13, 3.2.9, 3.2.6)
$ gem uninstall rails -v 4.0.0
You have requested to uninstall the gem:
rails-4.0.0
figaro-0.7.0 depends on [rails (< 5, >= 3)]
.....
.....

$ gem list | grep rails
rails (3.2.13, 3.2.9, 3.2.6)
$ rails -v
Rails 4.0.0
$ gem uninstall railties -v 4.0.0
You have requested to uninstall the gem:
railties-4.0.0
coffee-rails-4.0.0 depends on [railties (< 5.0, >= 4.0.0.beta)]
....
....
If you remove this gems, one or more dependencies will not be met.

$ tail `which rails`
str = ARGV.first
str = str.dup.force_encoding("BINARY") if str.respond_to? :force_encoding
if str =~ /\A_(.*)_\z/
version = $1
ARGV.shift
end
end
gem 'railties', version
load Gem.bin_path('railties', 'rails', version)
