@simonpeterdebbarma this could be because of node version - I will look into this in detail. In the meantime you can probably try upgrading your node. I have node - 10.4.2 and npm - 6.4.1 locally.

[wildeink]

Having the same issue even with an up-to-date node & npm.

[simondebbarma]

@tyroprogrammer The issue persists with an up-to-date node and npm.

[tyroprogrammer]

@simonpeterdebbarma, @wildeink - have you tried deleting node_modules and installing it again? In the root directory:

rm -rf node_modules
npm cache clean
npm install

[wildeink]

An updated version of eslint seems to be causing the failed build (for me). Adding SKIP_PREFLIGHT_CHECK=true to my .env file in the root allowed the app to build/start with npm and yarn.

[tyroprogrammer]

Hope what @wildeink suggested worked! Closing this issue for now.
