Cannot find module 'source-map-support"

[expoexpert125]

I tried running “expo diagnostics” and I’m getting this error. Originally, I had same error with expo build:web.

Anyone know why?

internal/modules/cjs/loader.js:883
throw err;

Try running npm install or yarn depending on which one you’re using to manage your dependencies.

If that doesn’t help, try removing node_modules and repeat the npm install or yarn.

If that still doesn’t work, maybe try removing package-lock.json/yarn.lock and repeat the above.
