Question

I created an angular project in visual studio code(version 1.81.1). but when I try to run the program using "ng serve" command give below error.(Node version : 20.6.0,npm version : 10.0.0)

Cannot redefine property: File

Execution policies set as below

Can give any reason for the issue?

Answer 1

There is an issue with node 20.6 that breaks babel. The fix for node has landed but not been released yet.

• issue for node
• issue for Babel

Downgrading to any previous version of Node (below 20.6) will fix the issue.

Babel has introduced a workaround in 7.22.17 with #15947 with allow Angular to run with 20.6.
