Cannot redeclare block-scoped variable 'ngDevMode'.

[igormap42]

After every npm install I'm getting an error:

node_modules/ngx-bootstrap-product-tour/node_modules/@angular/core/src/render3/ng_dev_mode.d.ts(9,11): error TS2451: Cannot redeclare block-scoped variable 'ngDevMode'.

If to delete @angular folder from node_modules/ngx-bootstrap-product-tour/node_modules, it's compiling. But still I need to delete it every time I'm installing smth. Is it possible to fix this error once and forever?

P.S. I'm using angular 5

remove node_modules from the package , it will work fine .

@salmaarsh06 thank you for your interest. The problem is that, as I wrote before, if to delete @angular folder or node_modules (the same) it works, but temporary. Every new call of npm install will retrieve the problem.

yeah , i experienced the same problem , but thats the only solution that worked for me .

any updates on this one? I'd love to try to use this but can't use it if I need to set up a script every time to clear that node_modules folder within the module each time

same problem here

I think the Angular dependencies should be moved to peerDependencies in package.json to solve this.
