“WARN peerdependencies” while installing Semantic-

I followed all the instructions posted on the Semantic-UI website in order to install the framework, namely:

Install node: I have confirmed it was installed properly by running node -v, to which I get "v0.12.7". Node is installed in /usr/local/include and I have already unpdated the $PATH to reflect the changes.
Install gulp: I ran sudo npm install -g gulp to install gulp globally in /usr/local/lib/node_modules (non-sudo command gave me errors and suggested the sudo command)

I cd to my project folder and run "npm install semantic-ui --save", to which I get:

Instead of simply:

npm WARN excluding symbolic link tests/withsymlinks/.hidden -> ../shown/.hidden                         
npm WARN excluding symbolic link tests/withsymlinks/bar.txt -> ../shown/bar.txt                         
npm WARN excluding symbolic link tests/withsymlinks/.hidden -> ../shown/.hidden                         
npm WARN excluding symbolic link tests/withsymlinks/bar.txt -> ../shown/bar.txt

which are the warning that the instructional video in the semantic-ui website suggests.

(I apologize for the long text)

After running it it does not do anything unless I Ctrl-C the process. I never reach the customization panel that the video in the following link gets to after running the command:

http://semantic-ui.com/introduction/getting-started.html#using-build-tools

The link also suggested other methods of installing npm and node and I tried additional ones (always cleaning the system thoroughly before each attempt) and it seems that I install those correctly and with their paths inside the ~/.bashrc file. How shall I proceed?

This problem happens because npm will be changing the way peer dependencies work in version 3.

This issue is also covered in Semantic UI issues, but seems to be resolved now. Please try again and make sure you give it enough time (up to 10-15 minutes, though it should take less than that). If you still have problems, try to use the latest Semantic UI from the github repo:

git clone https://github.com/Semantic-Org/Semantic-UI.git
cd Semantic-UI
npm install

This should have the same effect as running npm install semantic-ui --save so you'll get the interactive installer as soon as npm install finishes.
