### Desired functionality
<!--
My application was working fine when angular 5.2.1 but now many packages are giving errors. It was basically developed in bootstrap 3.3.7 . Now everything has been disturbed. My application design is disturbed. I have removed successfully the bugs in code after upgrade but now dependent packages are creating issues. I want to use angular material, bootstrap latest version and toasty and other packages and wants to be working.

Your response 'll be appreciated.

and when i am trying to build my source then getting typescript errors:

please see it
@angular/compiler-cli@6.0.4 requires typescript@'>=2.7.0 <2.8.0' but 2.9.1 was found instead.
Using this version can result in undefined behaviour and difficult to debug problems.

Please run the following command to install a compatible version of TypeScript.

npm install typescript@'>=2.7.0 <2.8.0'

To disable this warning run "ng config cli.warnings.typescriptMismatch false".

ERROR in ./src/main.ts
Module build failed: Error: Angular Compiler was detected but it was an instance of the wrong class.
This likely means you have several @ngtools/webpack packages installed. You can check this with npm ls @ngtools/webpack, and then remove the extra copies.

The warnings you are seeing are because you have invalid peer dependencies:

npm WARN @angular-devkit/build-webpack@0.7.0-beta.2 requires a peer of webpack@~4.6.0 but none is installed. You must install peer dependencies yourself.
npm WARN @ngtools/webpack@6.1.0-beta.2 requires a peer of typescript@~2.4.0 || ~2.5.0 || ~2.6.0 || ~2.7.0 but none is installed. You must install peer dependencies yourself.
npm WARN @ngtools/webpack@6.0.0-beta.7 requires a peer of typescript@~2.5.0 | ~2.6.0 | ~2.7.0 but none is installed. You must install peer dependencies yourself.
npm WARN @angular/compiler-cli@6.0.4 requires a peer of typescript@>=2.7.2 <2.8 but none is installed. You must install peer dependencies yourself.
npm WARN @ngtools/webpack@6.0.8 requires a peer of typescript@~2.4.0 || ~2.5.0 || ~2.6.0 || ~2.7.0 but none is installed. You must install peer dependencies yourself.
npm WARN karma-jasmine-html-reporter@1.1.0 requires a peer of jasmine@>=3 but none is installed. You must install peer dependencies yourself.
npm WARN ng2-toasty@4.0.3 requires a peer of @angular/core@^2.4.7 || ^4.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN ngx-bootstrap@3.0.0 requires a peer of @angular/forms@6.0.1 but none is installed. You must install peer dependencies yourself.
npm WARN tsickle@0.29.0 requires a peer of typescript@>=2.4.2 <2.9 but none is installed. You must install peer dependencies yourself.

The most important one is that you have TypeScript 2.9.1 in your package.json but all those dependencies need TypeScript 2.7.2.

If you go through the peer dependency messages one by one and install the correct package version (the one they ask for) those warnings will go away.
