Hi there,
I’m trying to start ionic on browser using “ionic serve --l” but after simulation start I’m getting this error after I have updated some outdated packages:
undefined is not an object (evaluating ‘WEBPACK_IMPORTED_MODULE_0__angular_core[“ɵreflector”].reflectionCapabilities = new WEBPACK_IMPORTED_MODULE_0__angular_core"_42" /* ɵReflectionCapabilities */’)
What can be the problem?
Try deleting your node_modules directory, then:
npm install
ionic serve
@robinyo I’ve tried but I’m still having the same error. However, at the end of rpm install I get this WARNING:

Maybe the problem could be here?
Looks like you have a lot of peer dependency issues to address 
@robinyo please can you suggest me how to solve this situation? I’m stuck at this point 
Sort out all your peer dependency issues. Then work to remove all your warnings and/or errors.
