The error message "Cannot redeclare block-scoped variable 'tz'" is shown when trying to use Ionic 2 along with angular-moment-timezone

Today, I installed angular-moment-timezone in my Ionic project and everything was working fine. However, after removing the node_modules folder and then running npm i, I started getting errors whenever I tried to run ionic serve. These are the errors I am seeing:

Typescript Error

Cannot redeclare block-scoped variable 'tz'.
node_modules/@types/moment-timezone/index.d.ts

undefined
undefined

Typescript Error

Cannot redeclare block-scoped variable 'tz'.
node_modules/angular-moment-timezone/node_modules/@types/moment-timezone/index.d.ts

undefined
undefined

I have searched for a solution but haven't been able to find one yet. Has anyone else encountered the same issue?

Answer №1

The presence of @types/moment-timezone in our dependencies is the cause of the error we are experiencing.

An issue arises stating "cannot redeclare block-scoped variable 'tz' moment-timezone"

Starting from version 0.5.30, d.ts files will now be located within moment-timezone itself. To resolve this, you can safely remove it by running:

npm uninstall @types/moment-timezone
