postinstall script crashes consumer application

[bennycode]

Describe the bug
I published an application on npm which uses caporal as dependency. When installing my application as a global node package, I am getting the following error:

C:\Users\bennyn>npm i -g swaxios
C:\Users\bennyn\AppData\Roaming\npm\swaxios -> > C:\Users\bennyn\AppData\Roaming\npm\node_modules\swaxios\dist\cli.js
[email protected] postinstall C:\Users\bennyn\AppData\Roaming\npm\node_modules\swaxios\node_modules\core-js
node -e "try { require('./scripts/postinstall'); } catch (e) { /* empty */ }"
