ERROR: Error installing jekyll: ERROR: Failed to build gem native extension

问题

My system has:

ruby 2.0.0p451 (2014-02-24) [x64-mingw32]
gem -version 2.2.2
devKit : DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe

When I try to run gem install jekyll, I get this error:

D:\devKit>gem install jekyll
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing jekyll:

I got this error while installing Jekyll on Linux (Mint 17, which is based on Ubuntu 14.04).

I eventually found the solution here. I needed both the ruby-dev package and nodejs (the latter due to a bug in Jekyll).

sudo apt-get install ruby ruby-dev make
sudo gem install jekyll --no-rdoc --no-ri
sudo apt-get install nodejs

I ran into this problem too. Running the following installed Jekyll for me:

$ \curl -L https://get.rvm.io | bash -s stable --rails --autolibs=enabled

$ sudo gem install jekyll

This installs RVM, updates Rails and installs Jekyll.

BTW - Most of the posts I've found indicate it's a problem with Xcode not having the developer tools installed. I have a newer MacBook Pro on which this stuff was installed by default, so attempting to install the Xcode dev tools did nothing for me (unlike the above, which did everything I needed).
