SyntaxError in dependency

[AngelaMariaDespotopoulou]

I believe line2 in provisioners/install-ngx.sh creates a breaking error.

default: /usr/lib/node_modules/generator-ngx-rocket/cli/index.js:250
default: } catch {
default: ^
default:
default: SyntaxError: Unexpected token {
default: at new Script (vm.js:51:7)
default: at createScript (vm.js:136:10)
default: at Object.runInThisContext (vm.js:197:10)
default: at Module._compile (internal/modules/cjs/loader.js:618:28)
default: at Object.Module._extensions..js (internal/modules/cjs/loader.js:665:10)
default: at Module.load (internal/modules/cjs/loader.js:566:32)
default: at tryModuleLoad (internal/modules/cjs/loader.js:506:12)
default: at Function.Module._load (internal/modules/cjs/loader.js:498:3)
default: at Module.require (internal/modules/cjs/loader.js:598:17)
default: at require (internal/modules/cjs/helpers.js:11:18)
default: rm: cannot remove 'package.json': No such file or directory

Something like this

sudo npm install -g generator-ngx-rocket@6.2.1

bypasses the particular error but the application still does not appear on localhost:8080.

In all probability dependencies need some revising.
