I have the following version

Angular CLI: 7.3.4
Node: 10.19.0
OS: linux x64
Angular: 7.2.7
... animations, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, platform-server, router
... service-worker

Package                           Version

webpack                           4.29.0

I installed V6.4.1 and everything worked as expected when I run npm start but when I want to build the app npm run build I get the following error:

ERROR in ./node_modules/ng2-pdf-viewer/fesm5/ng2-pdf-viewer.js
Module build failed (from ./node_modules/@angular-devkit/build-optimizer/src/build-optimizer/webpack-loader.js):
TypeError: Cannot read property 'kind' of undefined

Please advice,

Most likely due to the typescript version, 6.4.1 was built with "typescript": "~3.6.5",

[yabasha]

Do you suggest update typescript? And to which version?

[VadimDez]

Since you're using 6.4.1 try upgrading to at least "typescript": "~3.6.5" and see if you can build your project successfully.

[yabasha]

do you suggest other version of ng2-pdf-viewer that will work with Angular 7.2.7, because when I tried to update typescript version it generated ERROR in The Angular Compiler requires TypeScript >=3.1.1 and <3.3.0 but 3.6.5 was found instead
