SemanticUI and Aurelia installation error


Hi everyone,
I’m stuck installing SemanticUI alongside the Aurelia framework.
I started a new Aurelia CLI project with:
$ au new
and named it “semantic-cli”. Then I:
$ cd semantic-cli
$ npm install
$ npm install semantic-ui --save
and I get the following error:

semantic-ui@2.2.4 install /home/alex/tests/web/aurelia/customized/semantic-cli/node_modules/semantic-ui
gulp install

npm ERR! Please include the following file with any support request:

the node / npm versions are reported in the error log, whereas:
$ gulp --version
[16:07:54] CLI version 3.9.1
[16:07:54] Local version 4.0.0-alpha.2
I update all of these to the latest versions but I still had no luck…
Any idea how can I fix this?
