When you install it there are multiple warnings. Please update the dependencies

npm WARN deprecated request@2.88.2: request has been deprecated, see request/request#3142
npm WARN deprecated core-js@2.6.12: core-js@<3.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.
npm WARN deprecated nomnom@1.5.2: Package no longer supported. Contact support@npmjs.com for more info.
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
