Could not resolve dependency: jasmin-core, karma-jasmine-html-reporter

Ionic Framework

Hey guys,

I have:

Windows 10, 64bit

node -v
v16.4.2

npm -v
7.18.1

ionic -v
6.16.3

ionic start myapp blank --type=angular --capacitor

it throws error:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: ionic-app-base@0.0.0
npm ERR! Found: jasmine-core@3.7.1

I have cleared npm cache, deleted all the nodejs files and folders, reinstalled nodejs but its all same.

After googling, I found that web - unable to resolve dependency tree error for creating new angular project - Stack Overflow

In broken app directory, editing package.json
change this

"karma-jasmine-html-reporter": "^1.5.0",

to:

"karma-jasmine-html-reporter": "~1.5.0",

and after that run npm install fixes error.

It’s quite troublesome to do it manually after every project start.

Does anyone face this problem?

I have the same problem, I also cleared npm cache and reinstalled :stuck_out_tongue: . And editing package.json works, but while the problem starts installing capacitor, you have to install capacitor manually then.

I’m having the same problem even without installing the capacitor initially.
