ERROR in src/app/app.module.ts(6,10): error TS2305: Module '/node_modules/@angular/material/material"' has no exported member 'MdButtonModule'

Hi Guys ,

Today I have faced this error :

ERROR in src/app/app.module.ts(6,10): error TS2305: Module '"F:/shahbaz/study/angular4/projects/reactiveForm/FormVal/node_modules/@angular/material/material"' has no exported member 'MdButtonModule'.

I got this error just after I installed angular meterial module which was missing.

The full stack trace is as below :

ERROR in src/app/app.module.ts(6,10): error TS2305: Module '"F:/shahbaz/study/angular4/projects/reactiveForm/FormVal/node_modules/@angular/material/material"' has no exported member 'MdButtonModule'.

src/app/app.module.ts(6,26): error TS2305: Module '"F:/shahbaz/study/angular4/projects/reactiveForm/FormVal/node_modules/@angular/material/material"' has no exported member 'MdInputModule'.

src/app/app.module.ts(6,41): error TS2305: Module '"F:/shahbaz/study/angular4/projects/reactiveForm/FormVal/node_modules/@angular/material/material"' has no exported member 'MdCardModule'.

The solution is to replace modules which are deprecated in angular material with new ones.

MdButtonModule MdInputModule MdCardModule should be replaced with MatButtonModule MatInputModule MatCardModule 

Module not found: Error: Can't resolve 'hammerjs'

Hi Guys ,

Today I have faced this error :

Module not found: Error: Can't resolve 'hammerjs'

I faced this error since i didn't installed material module. Here's the solution if you face the same  issue.
Go to the command prompt and type the following command:

npm install --save hammerjs

Once installed ng serve,it should work.

Generally we get Module not found error means a module is missing . So we need to install the missing module in node js through npm tool.

After the module is installed verify the path ../node_modules there should be a folder created like this.

\hammerjs

The app should be restarted .
