ionic project failed to build after installing ngx-mqtt

[dev008webO]

I've just setup a new ionic app and after installing ngx-mqtt with npm install [email protected] --save it stopped building the project and says
typescript: node_modules/@types/node/index.d.ts
Subsequent variable declarations must have the same type. Variable 'process' must be of type '{ env: { [key: string]: string; }; }', but here has type 'Process'. L47: declare function setImmediate(callback: (...args: any[]) => void, ...args: any[]): any; L48: declare function clearImmediate(immediateId: any): void;.

Here is my package.json.

Would you be so kind and follow the issue template!?
[EDIT] This especially means I want a repository with your reproduction of your issue.

Here is the repo i've created. https://github.com/dev008webO/ionic-mqtt-demo.git. i've just made a new ionic project and installed ngx-mqtt by npm install [email protected] --save. and it giving this error at time of ionic serve.

The ionic project hast the same error in their examples, so I think this might be something on their side.
ionic-team/ionic-cli#3541
I'll keep this issue open, but won't work on it, since I wan't to wait how the referenced one develops.

[sclausen]

@dwieeb has a plausible explanation where this error may come from and I think we just have to wait until he resolves this issue.

@dev008webO do the recent comments in the issue mentioned above help you?

It worked. Try the solution of @dwieeb from https://github.com/ionic-team/ionic-cli/issues/3541. Just deleted src/declarations.d.ts file from project. and it worked. Thank you so much @sclausen
