I have created an FAIcon Module and i am using FaiconLibrary.addIcons() method to include few icons. This was working perfectly fine but just now, i got fresh copy and did npm install and started getting following error. I tried removing node_modules and did clean cache as well, did't work.

 error TS2345: Argument of type 'import("/node_modules/@fortawesome/free-solid-svg-icons/node_modules/@fortawesome/fontawesome-common-types/index").IconDefinition' is not assignable to parameter of type 'import("/node_modules/@fortawesome/fontawesome-common-types/index").IconDefinition'.
  Types of property 'iconName' are incompatible.
    Type 'import("/node_modules/@fortawesome/free-solid-svg-icons/node_modules/@fortawesome/fontawesome-common-types/index").IconName' is not assignable to type 'import("/node_modules/@fortawesome/fontawesome-common-types/index").IconName'.
      Type '"acquisitions-incorporated"' is not assignable to type 'IconName'.

24        library.addIcons(faEye);

This is how it is implemented.

It is a version mismatch issue https://github.com/FortAwesome/angular-fontawesome/issues/125
