Hi @Santhosh_Kumar_K

Welcome to the CHT Forum!

After installing new dependencies, please make sure that you run `grunt` (or `grunt dev-webapp`) first, which should resolve shared libraries symlinks correctly.

Could you please check the output of the `grunt` command?  
I’m particularly interested in the output of the installation task. You should be able to find it if you look for

```auto
Running "exec:npm-ci-modules" (exec) task

```
