With Ruby, does "gem install" use "--include-dependencies"... just the doc is a little outdated?
提问by nonopolarity
Using Ruby on Rails, if I do a
使用 Ruby on Rails，如果我做
gem help install
a part of it says:
它的一部分说：
-y, --include-dependencies Unconditionally install the required
dependent gems
[...]
Defaults:
--both --version '>= 0' --rdoc --ri --no-force
--no-test --install-dir c:/ruby/lib/ruby/gems/1.8
but if I do a
但如果我做一个
gem install --include-dependencies mysql
a line says:
一行说：
INFO: `gem install -y` is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
so looks like gem installalways use --include-dependenciesnow? Just the docs of gem help installis a little outdated?
所以看起来gem install总是使用--include-dependencies现在？只是文档gem help install有点过时了？

Yes, the documentation is a bit outdated.
是的，文档有点过时了。
gem install --include-dependencies option has been default for some time now.
gem install --include-dependencies 选项已经默认了一段时间了。

The command is now -include-dependencies, not --include-dependenciesI have used it this way:
命令是 now -include-dependencies，而不是--include-dependencies我这样使用它：
I have tried to install compass 0.12.3 dependencies and I have done it with this command, but this installed only dependencies not compass with them
我试图安装指南针 0.12.3 依赖项，我已经用这个命令完成了，但这只是安装了依赖项，而不是指南针
gem install compass -v 0.12.3 -include-dependencies
