Does this stop you from using Cursor

Yes - Cursor is unusable

It can break many electron app i guess

unset ELECTRON_RUN_AS_NODE fixes the problem. But I guess this is a bug for Cursor.

[Moumouls (Antoine Cormouls)]

Yes unset works bug, cursor should not inject this kind of var

[Moumouls (Antoine Cormouls)]

Bigger problem here NODE_ENV is also manipulated by cursor shell with “production” to true, so now our agent cant run tests properly by default

@condor @deanrie opened since one week now and it’s a major regression
