Both the CLI and generated project have dependencies that require Node 6.9.0 or higher, together with NPM 3 or higher, please update your node and npm.

Hi ragueshvr, Thanks for reply. Getting similar error with node 6.11.0 and npm 3.8.8 $ npm install -g @angular/cli C:\Users\rortscam\AppData\Roaming\npm\ng -> C:\Users\rortscam\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng C:\Users\rortscam\AppData\Roaming\npm `-- @angular/[email protected] npm WARN optional Skipping failed optional dependency /@angular/cli/chokidar/fsevents: npm WARN notsup Not compatible with your operating system or architecture: [email protected]

Are you getting any error related to node-gyp? This is most probably something that is mentioned here #1560 (comment)

Also, can you please get the complete log from the console?

That's the complete log:

This seems to be an optional dependency warning only, See if you have angular-cli installed with below command:

ng -v

--no-optional flag with npm install, should get rid of those though.
npm install --no-optional @angular/cli

[filipesilva]

Yeah that is just a warning, and is fine. It's a dependency that's only really needed for OSX systems. Thanks to @rageshvr for helping out!
