Installation fails on youtube-dl - Installation dependencies?

Hello,

I’m installing the most recent version of node an npm via these instructions: https://websiteforstudents.com/install-the-latest-node-js-and-nmp-packages-on-ubuntu-16-04-18-04-lts/

When i run npm install -g udacimak I get the following error:

> youtube-dl@1.12.2 postinstall /usr/lib/node_modules/udacimak/node_modules/youtube-dl
> node ./scripts/download.js

/usr/lib/node_modules/udacimak/node_modules/mkdirp/index.js:90
                    throw err0;
                    ^

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

I’m new to node and npm but know linux and other languages pretty well. I’m clearly missing something here.

Is there a specific way i need to install youtube-dl? I’m on ubuntu 16.04

Have you tried sudo npm i -g udacimak?

If that doesn’t work, try installing yarn and install via yarn instead and let me know if it works?

npm i -g yarn
# then
yarn global add udacimak

This works for me. sudo npm install -g udacimak --unsafe-perm=true --allow-root
