Can't run a simple Ionic app after generating it with yo jhipster-ionic

[CRivasGomez]

Hi! 👋

I always encounter this problem while running a fresh new generated Ionic app.

Overview of the issue - if an error is being thrown a stack trace helps

After generating my Ionic app as specified in the README.md it can't run it without error.
It says:

Typescript Error
Subsequent variable declarations must have the same type. Variable 'process' must be of type '{ env: { [key: string]: string; }; }', but here has type 'Process'.
node_modules/@types/node/index.d.ts

Motivation for or Use Case - explain why this is a bug for you

I can't generate runnable Ionic apps from JHipster generated runnable apps.

Reproduce the error - an unambiguous set of steps to reproduce the error. If you have a JavaScript error, maybe you can provide a live example with JSFiddle?

mkdir -p myapp/backend
cd myapp/backend
jhipster
(...)
cd ..
yo jhipster-ionic
(...)
cd ionic4j
ionic serve

Related issues - has a similar issue been reported before?

No.

Suggest a Fix - if you can't fix the bug yourself, perhaps you can point to what might be causing the problem (line of code or commit)

The screenshot shows a suspicious part of code inside node_modules/@types/node/index.d.ts.

JHipster Version(s) - is it a regression?
4.14.5

JHipster configuration, a .yo-rc.json file generated in the root folder - this will help us to replicate the scenario, you can remove the rememberMe key.

@CRivasGomez Can you try removing src/declarations.d.ts from your project as suggested and see if that fixes it?

Hey!

I resolved it by restarting my machine. Now is working as is supposed to do.

This is very strange because I have been dealing with this problem for 2 days before opening this issue and in that period of time I have rebooted my machine at least 2 times and tried again to generate all the projects multiple times.

I'am trying to reproduce the error but I can't.

Anyways, thanks for your time @mraible 👍
