Ngrx effects on lower version of typescript doesn't work

问题

I have an Ionic 3 App where I use ngrx/store and ngrx/effects. But each time I try to run the app it sais this error below:

TypeScript Error A computed property name in a type literal must directly refer to a built- in symbol. ...: Cannot find name 'any'.

which refers to this folder in my node modules node_modules/@ngrx/effects/src/on_run_effect.d.ts

to this block of code below:

export declare function isOnRunEffects(sourceInstance: {
    [onRunEffectsKey]?: onRunEffectsFn;
}): sourceInstance is OnRunEffects;

This can be fix by installing higher version of typescript but as of now currently I am using 2.6.1 but when I upgrade it to a higher version of typescript my app doesn't work on production and even the console.log methods are not working.

here is my ionic info below:

Ionic:

   ionic (Ionic CLI)  : 4.0.0-rc.13 (/home/clifford/.npm-global/lib/node_modules/ionic)
   Ionic Framework    : ionic-angular 3.9.2
   @ionic/app-scripts : 3.2.0

Cordova:

   cordova (Cordova CLI) : 8.0.0
   Cordova Platforms     : browser 5.0.4

System:

   Android SDK Tools : 26.1.1
   NodeJS            : v6.12.2 (/usr/local/bin/node)
   npm               : 4.6.1
   OS                : Linux 4.13

Environment:

   ANDROID_HOME : /home/clifford/Android/Sdk

Appreciate if someone could help. Thanks in advance.

May be you are using latest version which is internally uses typescript 3.1.x. Please try to downgrade to the specific version (5.2.0) for typescript 2.6.x. and check it.

npm install @ngrx/store@5.2.0 @ngrx/effects@5.2.0 --save
