I would like a little help from you with this problem that's make me crazy (Maybe it's an Obsessive Compulsive Disorder ¯ \ _ (ツ) _ / ¯ )

I have a project with Nodejs + Angular + Ionic that seems to have dependency problems when checking with the "node ls" command in your own folder i see "unmet peer dependency".

In "npm install" just showing warnings, but in "npm ls" show "unmet peer dependency". What is the relationship? And how can I do to solve it?

I have already updated nodejs 7.8.0, I have already re-installed the dependencies in the project folder with "npm install", but it still has not solved.

Command output "npm ls" that presents errors ...

Thank you all

These are happening because
let assume there are 4 modules=> a,b,c,d
so, a dependent on b,
b dependent on c
but d version dependent on c (old version).
Now c new version cannot matched with the c of old version hence unmeet dependency.
(solution):=
remove node_modules and install again
or update d

  • I was updating some dependencies, randomly, in the package.json for newer stable versions. So with your answer, I realized the error @Vinayk93 and i decided to follow the suggestion of dependencies in the git project much as possible. Here the sugestion/version before updating for angular4 in ionic project [Link] (https://github.com/driftyco/ionic/blob/e07aad460d2c3e1c3f3395dd5ecdcfb7d067c72e/package.json) And the update for angular4 dependencies in ionic project. [Link] (https://github.com/driftyco/ionic/blob/master/package.json) Look This Can Prevent Headaches Thank you – Rodrigo Silveira Mar 29 '17 at 21:38
