Path with spaces, that is the issue.

https://github.com/oneclick/rubyinstaller/wiki/Troubleshooting#wiki-gems_fails

When you install Ruby using either RubyInstaller or RailsInstaller, it
warns you about path with spaces (above the field you enter the path
for installation).

Install outside a path with spaces and things will work.

Thank you for the answer - It Works now,

but i have other problem :

Unless you're using "gem server" to look at ActiveSupport
documentation you can install gems with --no-ri --no-rdoc options.

You should update to latest rdoc gem so solve this encoding issue.

Last but no least, try to use a console codepage that plays nicely
with UTF-8, seems IBM866 is your current codepage, please change it to
windows-1251:

Type:

chcp 1251

At the command prompt before doing anything.

If you want to make a permanent change, see here:

Interesting is after running again - gem install rails

Everything was okay without error or warning.

But i do what you say.

Thank you very much!
