How to use rails within Cygwin

I have installed rails using rubystack and set env path, so I can use 开发者_JAVA百科it in cmd. When I try to use it with cygwin I doesn't work (it shouldn't), how to make this rails work on both windows and cygwin env or I have to install it separately.

If you are just looking to install so you can use it in cmd, then you can do this without having to use Cygwin. You can download and install ruby and rubygems in windows and then use rubygems to install rails and any other gems you need. You then just have to set the path properly to include the bin directory of the ruby installation and you should be able to use ruby from cmd in windows. This doesn't directly answer your questions I know, but if you are just looking for rails in the cmd, I hope it is helpful.

Update: I found two items which fixed the problem I outlined below.

Firstly

• Run Cygwin’s setup.exe and search for "make"
• Wait for search results
• Install all items which appear (you can do this by clicking near the top of the "tree")

Secondly

• Run Cygwin’s setup.exe and install the rebase package.
• Using the Windows cmd line (yes, it must be the Windows cmd line not cygwin!), run \cygwin\bin\ash
• At the ash prompt, run /bin/rebaseall

Restart Windows. Run cygwin. Run: gem install rails

I have installed Ruby via the cygwin setup file. I've also installed "make", "sqlite" and "openssl/openssh".

I've then sucessfully installed Gems by downloading from website, cd into /cygwin/bin/ and then into a temp directory and then running ruby setup.rb.

This all installed perfectly.

Now I run gem install rails. It fails producing the following error. I can't find any more info on this. Any help much appreciated.

gem install rails
