Node : v12.11.0
Npm: 6.11.3
Python: 2.7.16

Try to downgrade your Node version.
I've had the same issue after I upgraded from v12.8 => v12.11
After the downgrade it works again

I downgrade Node version from 12.11.10 to the last stable version 10.16.3 LTS and it worked for me.
Thanks @NyauIf

yes i am also facing this issues. actually Node.js Recommended For Most Users is version 10.16.3 LTS.
Using below choco command will install Latest version of 12.11.0.
choco install -y nodejs.install python2 jdk8

I downgrade Node version from 12.11.0 to 10.16.3 LTS and it worked for me.

Just downgrade the Node version it will work fine.
Best way to use https://github.com/nvm-sh/nvm
it helps to change the node version as required,

[friederbluemle]

Same problem here. The following fixed it:

choco uninstall nodejs
choco install nodejs-lts

[ricardo-morgilli]

I downgrade Node version:
choco install -y nodejs.install --version 10.16.3 --force

[rohanpadwalkar]

downgrading Node version worked for me.

Thanks everyone for help.

They should be working on compatibility with node 12 though, the 10.16.3 LTS node is going to be replaced by Node 12 in Oct. 22, 2019.

This issue should be reopened - following the documentation correctly leads to this failure, which means this is an open problem
