Hi. I’m getting this message when I try to build. I have no any warnings. How I can fix this error?

I also fixed the npm warning but the error continue to appear. Also how I can set EXPO_DEBUG=true? where?

first be on the latest version of exp, npm i -g exp,

What command are you running exactly?

To set an environment variable, type in shell: export EXPO_DEBUG=true

Yes. I use the latest version of exp (47.4.4).
Now I enabled the debug and got this message:

I solved my issue with rollback to an old exp version. you can do it by npm install exp@45.0.2 -g

That stinks, we aren’t logging enough information to easily diagnose the error. We’ll change that code to add more details about the problem and keep investigating. In the meantime you can continue using 45.0.2. Do you have a build id we could look at?

@dooboolab, just in case your situation is different, could you also repeat the steps edgar gave?

  • Run npm install -g exp to be sure you’re on the latest version.
  • Tell us exactly what command you’re running.
  • Run export EXPO_DEBUG=true and try that command again.
