问题
I'm getting an empty report, it's listing the files but it's not filling up the percentages... Any idea on what can be causing it?
Error message:
Handlebars: Access has been denied to resolve the property "statements" because it is not an "own property" of its parent.
My package.json file:

回答1:
The package "karma-coverage-istanbul-reporter" was out-of-date. After I execute the following npm update statement "npm i -D karma-coverage-istanbul-reporter@2.1.1", it is working again.
