Error npm UNMET PEER DEPENDENCY warning

Question

I'm on Windows 10, with Node 5.6.0 and npm 3.6.0. I'm trying to install angular-material and mdi into my working folder. npm install angular-material mdi errors with:

+-- angular@1.5.0

+-- UNMET PEER DEPENDENCY angular-animate@^1.5.0

+-- UNMET PEER DEPENDENCY angular-aria@^1.5.0

+-- angular-material@1.0.6

+-- UNMET PEER DEPENDENCY angular-messages@^1.5.0 `-- mdi@1.4.57

npm WARN enoent ENOENT: no such file or directory, open
'C:\Users\xxxxx\Desktop\ngClassifieds\package.json' 

npm WARN angular-material@1.0.6 requires a peer of
angular-animate@^1.5.0 but none was installed. 

npm WARN angular-material@1.0.6 requires a peer of angular-aria@^1.5.0
but none was installed. 

npm WARN angular-material@1.0.6 requires a peer of
angular-messages@^1.5.0 but none was installed.

How do I resolve this to get AngularJS Material and MDI installed?

Hello @kartik,

UNMET PEER DEPENDENCY error is thrown when the dependencies of one or more modules specified in the package.json file is not met. Check the warnings carefully and update the package.json file with correct versions of dependencies.

Then run

rm -rf node_modules/
npm cache clean
npm install

This will install all the required dependencies correctly.

Hope this is helpfull!!

Thank You!!
