[FIXED] How do I fix the npm UNMET PEER DEPENDENCY warning?

Issue

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?

Solution

npm no longer installs peer dependencies so you need to install them manually, just do an npm install on the needed deps, and then try to install the main one again.

Reply to comment:

it's right in that message, it says which deps you're missing

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` 

So you need to npm install angular angular-animate angular-aria angular-material angular-messages mdi
