This problem occurs doing a fresh install, following installation instructions.

Be great if someone can answer this ticket with a fix or work around.

Thanks.

davidfavor commented 7 years ago

@sakonachhoeurng, likely the following will fix your JSON error.

npm install json -g

sakonachhoeurng commented 7 years ago

@davidfavor I still got that error the same.

davidfavor commented 7 years ago

Error still persists.

Be great if someone can provide suggestions towards a fix.

davidfavor commented 7 years ago

@sakonachhoeurng , jsDom version change to the oldest version.

calebolin commented 6 years ago

I'm having this issue too. Has this project been abandoned?

davidfavor commented 6 years ago

This project seems dead.

Many issues have no developer response.
