Karma Jasmine does not set

Question

I'm new to Unit Testing, so I got to know Jasmineand Karmatoday.

I installed Karma:

npm init
npm install karma --save-dev
npm install -g karma-cli
npm install karma-jasmine --save-dev
npm install karma-chrome-launcher --save-dev
karma init

However, when I try to start the beginning of karma karma.conf.js, this causes me an error:

Error: Cannot find module 'jasmine-core'

I tried installing the kernel globally:

npm install -g jasmine-core

but that did not solve it.

When I try to install npm install karma-jasmine, I get an error message:

 karma-jasmine@0.3.6 requires a peer of jasmine-core@* but none was installed.

Answer 1

https://github.com/karma-runner/karma-jasmine

Note. Since karma-jasmine 0.3.0, the jasmine library is no longer associated with karma-jasmine, and you must install it yourself. You can simply do this:

npm install jasmine-core --save-dev

$ npm install jasmine-core --save-dev
$ npm install karma-jasmine --save-dev
