Here are the setup I have taken

1. npm-check-updates -u get packages that need updating
2. npm-check-updates -a apply updates on packages
3. npm install

and thats when I get the error. Hope that helps.

I believe the issue might be related to peerDependencies in the package.json.

[jimboweb]

limpep can you explain that please? I'm having the same problem and don't know how to fix it.

[limpep]

@jimboweb first of all this isn't really a issue as the functionality of the library still works, this is just a warning and there is a pull request to fix this https://github.com/cstefanache/angular2-img-cropper/pull/195, it just hasn't been merged yet by @cstefanache .

[jimboweb]

Okay, I figured it out. If someone else is having this problem, you need to do yarn install or npm install in the directory and then ./mvnw to start it.
